| titletext = If you live in the Northern hemisphere, anyway. In the southern hemisphere, due to the coriolis effect, babies are born nine months BEFORE they're conceived.&lt;br /&gt;
}}&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{w|Horoscopes}} purport to predict someone's personality or future, based on the position of planets and stars at the time of their birth and at present. Horoscopes commonly group people into twelve groups based on {{w|zodiac signs}}. The Zodiac signs are based on twelve constellations that are the backdrop for the path of the sun, moon and planets through the night sky. One's zodiac sign is determined by the position of the sun on their birthday, with each sign representing a specific 30.4 day period.&lt;br /&gt;
&lt;br /&gt;
Today, horoscopes are known to have {{w|Astrology and science|no basis in science}}, which is why the comic jokes about the fact that its horoscopes at least ''may'' be true. Actual horoscopes are typically so vague that they could be true for almost anyone regardless of their sign. Note that this horoscope is tailored for an audience in the {{w|United States}}, as most cultural references are centered on &amp;quot;Western&amp;quot; culture, and several won't even work in Europe, for example. With the principle understood, it is easy to apply local traditions for more accuracy in non-Western cultures, however.&lt;br /&gt;
&lt;br /&gt;
Since the 12 category zodiac signs in horoscopes are based on birthday dates, [[Randall]] can do some informed guess about the context of someone's {{w|Fertilisation|conception}} (i.e., what was happening nine months before they were born, apart from the {{w|Sexual intercourse|obvious}}), depending on the sign. For example, {{w|Virgo (astrology)|Virgo}} are born between August 23 and September 22, so based on a 9-month gestational period, they were likely {{w|Fertilisation|conceived}} shortly before Christmas, leading to the guess &amp;quot;You may have been conceived while a Christmas song played&amp;quot;. Randall also phrases his &amp;quot;predictions&amp;quot; as possibilities (&amp;quot;you may have&amp;quot;) rather than declarations, acknowledging that unlike actual horoscopes, his don't necessarily apply to everyone. See detailed description in the [[#Table of Astrological signs|table]] below.&lt;br /&gt;
&lt;br /&gt;
The title text refers to the {{w|Coriolis effect}} which applies to a body that is moving relative to an object that is spinning. Since the Earth is rotating, a force (the Coriolis force) causes moving objects to be deflected to the right in the {{w|northern hemisphere}} and to the left in the {{w|southern hemisphere}}. This effect is the reason that {{w|Coriolis_effect#Meteorology|weather systems}} (most clearly seen for {{w|hurricanes}}) spiral in one direction in the northern hemisphere and in the opposite direction in the southern hemisphere.&lt;br /&gt;
&lt;br /&gt;
There is also a common {{w|Coriolis_effect#Draining_in_bathtubs_and_toilets|misconception}} that the Coriolis force in respect of the Earth affects objects on a much smaller scale, such as the direction water will spiral down a drain in the two hemispheres (see also [[843: Misconceptions]]). In reality, the relative rotational speed of the Earth (one rotation per day) is insufficient to effect anything but large-scale, relatively slow movement, such as weather patterns. (Randall plays on the misconception to make a joke involving reversing the flow of time. So whereas babies are born nine months '''after''' conception in the northern hemisphere (clockwise) the Coriolis effect is the reason why babies are being born nine months '''before''' in the southern hemisphere (counterclockwise).  Note that unlike these horoscopes, which are declared to have an &amp;quot;actual basis in fact&amp;quot;, there is no known fact that could cause a birth to happen nine months before that birth's conception.&lt;br /&gt;

|♈ {{w|Aries (astrology)|Aries}}&lt;br /&gt;
|The&amp;amp;nbsp;Ram&lt;br /&gt;
|March 21 - April 21&lt;br /&gt;
|June 14 - July 14&lt;br /&gt;
|You may have been conceived after a 4th of July fireworks show&lt;br /&gt;
|In the US the {{w|Independence Day (United States)|Independence Day}} is celebrated on the 4th of July, and this is customarily celebrated with huge fireworks.  Fireworks are also often used in movies to depict the culmination of sex (i.e. the orgasm), and hence the potential for conception.&lt;br /&gt;
|-&lt;br /&gt;
|♉ {{w|Taurus (astrology)|Taurus}}&lt;br /&gt;
|The&amp;amp;nbsp;Bull&lt;br /&gt;
|April 20 - May 20 &lt;br /&gt;
|July 13 - August 13&lt;br /&gt;
|You may have been conceived on a hot August day&lt;br /&gt;
|In most of the northern hemisphere there are many hot days in {{w|August}}.  Sometimes hot days increase lust, especially if it's too hot to go out or do anything else.&lt;br /&gt;
|-&lt;br /&gt;
|♊ {{w|Gemini (astrology)|Gemini}}&lt;br /&gt;
|The&amp;amp;nbsp;Twins&lt;br /&gt;
|May 21 - June 21&lt;br /&gt;
|August&amp;amp;nbsp;14 - September&amp;amp;nbsp;14&lt;br /&gt;
|You may have been conceived as the leaves began to change&lt;br /&gt;
|In the northern part of the northern hemisphere the {{w|autumn}} starts at the end of this time period, so the leaves will begin to change color.&lt;br /&gt;
|-&lt;br /&gt;
|♋ {{w|Cancer (astrology)|Cancer}}&lt;br /&gt;
|The&amp;amp;nbsp;Crab&lt;br /&gt;
|June 21 - July 21&lt;br /&gt;
|September 14 - October 14&lt;br /&gt;
|You may have been conceived by people trying on costumes&lt;br /&gt;
|This period ends 10 days before {{w|Halloween}}, so it is not unlikely that the people who conceived you (mom and dad) tried on their new costumes when they made you.  Roleplay, enhanced with costumes, can be a way to spice up a relationship and can lead to sex and procreation.&lt;br /&gt;
|-&lt;br /&gt;
|♌ {{w|Leo (astrology)|Leo}}&lt;br /&gt;
|The&amp;amp;nbsp;Lion&lt;br /&gt;
|July 22 - August 23&lt;br /&gt;
|October 15 - November 16&lt;br /&gt;
|You may have been conceived during thanksgiving&lt;br /&gt;
|{{w|Thanksgiving}} is celebrated in the US on fourth Thursday of November, which for only two out of seven years will lie before the 23rd of November.  However many people are born before 9 months so it is not unlikely for someone born as a Leo to be conceived on this day.&lt;br /&gt;
|-&lt;br /&gt;
|♍ {{w|Virgo (astrology)|Virgo}}&lt;br /&gt;
|The&amp;amp;nbsp;Maiden&lt;br /&gt;
|August&amp;amp;nbsp;23 - September&amp;amp;nbsp;22&lt;br /&gt;
|November 16 - December 15&lt;br /&gt;
|You may have been conceived while a Christmas song played&lt;br /&gt;
|It is very common for {{w|Christmas}} songs to be played in the month before Christmas.&lt;br /&gt;
|-&lt;br /&gt;
|♎ {{w|Libra (astrology)|Libra}}&lt;br /&gt;
|The&amp;amp;nbsp;Scales&lt;br /&gt;
|September 22 - October 23&lt;br /&gt;
|December 15 - January 16&lt;br /&gt;
|You may have been conceived after a new year's eve party&lt;br /&gt;
|Since {{w|New Year's Eve}} always falls on December 31, and since the party goes on into the new year this fits with Libra. As it is very likely that people are together in a way that may lead to conception at this type of parties, there may even be rather more than a 30th part of the people that are Libra that are conceived at such a party.&lt;br /&gt;
|-&lt;br /&gt;
|♏ {{w|Scorpio (astrology)|Scorpio}}&lt;br /&gt;
|The&amp;amp;nbsp;Scorpion&lt;br /&gt;
|October 23 and November 22&lt;br /&gt;
|January 16 - February 15&lt;br /&gt;
|You may have been conceived by people stuck inside after a long winter&lt;br /&gt;
|This period is during the coolest part and towards the end of the {{w|winter}} in the northern hemisphere. People may even be forced to stay at home due to snow. When people have nothing else to do [https://www.google.dk/search?q=babies+9+month+after+snowstorm&amp;amp;ie=utf-8&amp;amp;oe=utf-8&amp;amp;gws_rd=cr&amp;amp;ei=qzkuVcjAE4qsswGevoC4CQ many babies are born 9 months later].&lt;br /&gt;
|-&lt;br /&gt;
|♐ {{w|Sagittarius (astrology)|Sagittarius}}&lt;br /&gt;
|The&amp;amp;nbsp;Archer&lt;br /&gt;
|November 22 - December 21&lt;br /&gt;
|February 15 - March 14&lt;br /&gt;
|You may have been conceived during March madness&lt;br /&gt;
|Although originally the early part of the mating season for the {{w|European Hare}}, in which females fight off male suitors, in a US context this is an American college Basketball tournament [http://www.ncaa.com/march-madness].&lt;br /&gt;
|-&lt;br /&gt;
|♑ {{w|Capricorn (astrology)|Capricorn}}&lt;br /&gt;
|The&amp;amp;nbsp;Goat&lt;br /&gt;
|December 22 - January 19&lt;br /&gt;
|March 15 - April 12&lt;br /&gt;
|You may have been conceived during a sexy Easter Egg hunt&lt;br /&gt;
|{{w|Easter}} falls between {{w|List_of_dates_for_Easter#Earliest_Easter|March 22}} and {{w|List_of_dates_for_Easter#Latest_Easter|April 25}} so most {{w|Egg hunt|Easter Egg hunt}}, sexy or not, will fall in the relevant period to conceive Capricorn children. The goal of an Easter egg hunt can be to find as many eggs in a given time, or find a sequence of eggs, each containing a clue to the next. It is not difficult to think of adult variations on these themes. Most Egg hunts do not involve people who should make them sexy! On the other hand the egg itself, as an Easter symbol, is a symbol of fertility and after the little ones have gone to bed the adults may want to produce more little ones.&lt;br /&gt;
|-&lt;br /&gt;
|♒ {{w|Aquarius (astrology)|Aquarius}}&lt;br /&gt;
|The&amp;amp;nbsp;Water&amp;amp;nbsp;Carrier&lt;br /&gt;
|January 20 - February 18&lt;br /&gt;
|April 13 - May 11&lt;br /&gt;
|You may have been conceived on Mother's day&lt;br /&gt;
|{{w|Mother's Day}} in the USA,and some other countries, is on the second Sunday in May, between the 8th and 14th of May.  The husband of a Mother being celebrated may wish to show his appreciation for her by paying her special private attention, potentially leading to sex and conception.&lt;br /&gt;
|-&lt;br /&gt;
|♓ {{w|Pisces (astrology)|Pisces}}&lt;br /&gt;
|The&amp;amp;nbsp;Fish&lt;br /&gt;
|February 19 - March 20&lt;br /&gt;
|May 12 - June 13&lt;br /&gt;
|You may have been conceived at someone's wedding&lt;br /&gt;
|It may have been your own parent's wedding, as the traditional wedding honeymoon typically includes sex (potentially lots of it).  However, it is also not uncommon that other people meet and even go so far as to risk conceiving a child at someone's {{w|wedding}}, and June is widely reported as the [http://www.statista.com/statistics/241231/percentage-of-us-weddings-by-month/ most popular month for weddings in the United States]. The tradition of a June Bride (late spring and beginning of summer in the northern hemisphere) may be an old one and hence explains the reference for Pisces which lies mainly in June. [https://open.abc.net.au/explore/22074 ABC claim] that in the 15th and 16th century, May would have been the month for an &amp;quot;annual bath&amp;quot;, and moreover {{w|June}} is named for {{w|Juno (mythology)|Juno}}, goddess of marriage and childbirth. &lt;br /&gt;

==Explanation==&lt;br /&gt;
{{w|Horoscopes}} purport to predict someone's personality or future, based on the position of planets and stars at the time of their birth and at present. Horoscopes commonly group people into twelve groups based on {{w|zodiac signs}}. The Zodiac signs are based on twelve constellations that are the backdrop for the path of the sun, moon and planets through the night sky. One's zodiac sign is determined by the position of the sun on their birthday, with each sign representing a specific 30.4 day period.&lt;br /&gt;

Today, horoscopes are known to have little basis in science, which is why the comic jokes about the fact that its horoscopes at least ''may'' be true. Actual horoscopes are typically so vague that they could be true for almost anyone regardless of their sign. Note that this horoscope is tailored for an audience in the {{w|United States}}, as most cultural references are centered on &amp;quot;Western&amp;quot; culture, and several won't even work in Europe, for example. With the principle understood, it is easy to apply local traditions for more accuracy in non-Western cultures, however.&lt;br /&gt;
&lt;br /&gt;
Since the 12 category zodiac signs in horoscopes are based on birthday dates, [[Randall]] can do some informed guess about the context of someone's {{w|Fertilisation|conception}} (i.e., what was happening nine months before they were born, apart from the {{w|Sexual intercourse|obvious}}), depending on the sign. For example, {{w|Virgo (astrology)|Virgo}} are born between August 23 and September 22, so based on a 9-month gestational period, they were likely {{w|Fertilisation|conceived}} shortly before Christmas, leading to the guess &amp;quot;You may have been conceived while a Christmas song played&amp;quot;.

(Randall plays on the misconception to make a joke involving reversing the flow of time. So whereas babies are born nine months '''after''' conception in the northern hemisphere (clockwise) the Coriolis effect is the reason why babies are being born nine months '''before''' in the southern hemisphere (counterclockwise).  Note that unlike these horoscopes, which are declared to have an &amp;quot;actual basis in fact&amp;quot;, there is no known fact that could cause a birth to happen nine months before that birth's conception.&lt;br /&gt;

|This period ends 10 days before {{w|Halloween}}, so it is not unlikely that the people who conceived you (mom and dad) tried on their new costumes when they made you.  Roleplay, enhanced with costumes, can be a way to spice up a relationship and can lead to sex and procreation.&lt;br /&gt;

|July 22 - August 23&lt;br /&gt;
|October 15 - November 16&lt;br /&gt;
|You may have been conceived during thanksgiving&lt;br /&gt;
|{{w|Thanksgiving}} is celebrated in the US on fourth Thursday of November, which for only two out of seven years will lie before the 23rd of November.  However many people are born before 9 months so it is not unlikely for someone born as a Leo to be conceived on this day.&lt;br /&gt;
|-&lt;br /&gt;
|♍ {{w|Virgo (astrology)|Virgo}}&lt;br /&gt;
|The&amp;amp;nbsp;Maiden&lt;br /&gt;

|It is very common for {{w|Christmas}} songs to be played in the month before Christmas.&lt;br /&gt;

|December 15 - January 16&lt;br /&gt;
|You may have been conceived after a new year's eve party&lt;br /&gt;
|Since {{w|New Year's Eve}} always falls on December 31, and since the party goes on into the new year this fits with Libra. As it is very likely that people are together in a way that may lead to conception at this type of parties, there may even be rather more than a 30th part of the people that are Libra that are conceived at such a party.&lt;br /&gt;

|{{w|Easter}} falls between {{w|List_of_dates_for_Easter#Earliest_Easter|March 22}} and {{w|List_of_dates_for_Easter#Latest_Easter|April 25}} so most {{w|Egg hunt|Easter Egg hunt}}, sexy or not, will fall in the relevant period to conceive Capricorn children. The goal of an Easter egg hunt can be to find as many eggs in a given time, or find a sequence of eggs, each containing a clue to the next. It is not difficult to think of adult variations on these themes. Most Egg hunts do not involve people who should make them sexy! On the other hand the egg itself, as an Easter symbol, is a symbol of fertility and after the little ones have gone to bed the adults may want to produce more little ones.&lt;br /&gt;

|{{w|Mother's Day}} in the USA,and some other countries, is on the second Sunday in May, between the 8th and 14th of May.

|It may have been your own parent's wedding, as the traditional wedding honeymoon typically includes sex (potentially lots of it).  However, it is also not uncommon that other people meet and even go so far as to risk conceiving a child at someone's {{w|wedding}}, and June is widely reported as the most popular month for weddings in the United States[http://www.statista.com/statistics/241231/percentage-of-us-weddings-by-month/]. The tradition of a June Bride (late spring and beginning of summer in the northern hemisphere) may be an old one and hence explains the reference for Pisces which lies mainly in June. [https://open.abc.net.au/explore/22074 ABC claim] that in the 15th and 16th century, May would have been the month for an &amp;quot;annual bath&amp;quot;, and moreover {{w|June}} is named for {{w|Juno (mythology)|Juno}}, goddess of marriage and childbirth. &lt;br /&gt;

| titletext = If you live in the Northern hemisphere, anyway. In the southern hemisphere, due to the coriolis effect, babies are born nine months BEFORE they're conceived.&lt;br /&gt;
}}&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{w|Horoscopes}} are supposed to predict someone's personality or future, depending on the position of planets and stars at the time of their birth and presently, especially based on their ({{w|zodiac signs}}). Today, horoscopes are admitted to be {{w|pseudoscience}} which is why the comic jokes about the fact that its horoscopes at least ''may'' be true (at least for someone born in the {{w|United States}}, after a full term pregnancy). &amp;quot;Real&amp;quot; horoscopes are typically so vague that they could be true for anyone regardless of their sign.&lt;br /&gt;
&lt;br /&gt;
Since the 12 category zodiac signs in horoscopes are based on birthday dates, [[Randall]] can do some informed guess about the context of someone's {{w|Fertilisation|conception}} (i.e., what was happening nine months before they were born), depending on the sign. For example, {{w|Virgo (astrology)|Virgo}} are born mostly in September, so they were conceived shortly before Christmas, leading to the guess &amp;quot;You may have been {{w|Fertilisation|conceived}} while a Christmas song played&amp;quot;. So Randall's &amp;quot;predictions&amp;quot; are possible, if not useful. Contrary to popular horoscopes, here there is an actual reason why for instance the horoscope for Virgo is most likely true for Virgos and so on. See detailed description in the [[#Table of Astrological signs|table]] below.&lt;br /&gt;
&lt;br /&gt;
The title text refers to the {{w|Coriolis effect}} which occurs to a body that is moving on an object that is spinning. Since the Earth is rotating this leads to the fact that something that is moving on Earth feels a force (the Coriolis force) which causes the moving object to be deflected to the right in the {{w|northern hemisphere}} and to the left in the {{w|southern hemisphere}}. This effect is the reason that {{w|Coriolis_effect#Meteorology|weather systems}} (most clearly seen for {{w|hurricanes}}) rotates in one direction in the northern hemisphere and in the opposite direction in the southern hemisphere. There is also a common {{w|Coriolis_effect#Draining_in_bathtubs_and_toilets|misconception}} that water will spin down a plug hole in a different direction in the two hemispheres (see also [[843: Misconceptions]]). The Coriolis force can also be experienced on a much smaller scale, for instance if you try to walk on a spinning carousel. &lt;br /&gt;
&lt;br /&gt;
Randall plays on misconceptions regarding this {{w|fictitious force}} to make a joke involving reversing the flow of time. So whereas babies are born nine months '''after''' conception in the northern hemisphere (clockwise) the Coriolis effect is the reason why babies are being born nine months '''before''' in the southern hemisphere (counterclockwise).&lt;br /&gt;
&lt;br /&gt;
In reality, the relevant difference between the northern and southern hemispheres is that the meteorological seasons are a half-year out of phase between the two. This renders some of the &amp;quot;predictions&amp;quot; (such as a hot day in August or people trapped by snow in January-February) invalid for the southern hemisphere.&lt;br /&gt;
&lt;br /&gt;

|You may have been conceived after a 4th of July fireworks show&lt;br /&gt;
|In the US the {{w|Independence Day (United States)|Independence Day}} is celebrated on the 4th of July, and this is customarily celebrated with huge fireworks.&lt;br /&gt;
|-&lt;br /&gt;
|♉{{w|Taurus (astrology)|Taurus}}&lt;br /&gt;

|April 20 - May 20 &lt;br /&gt;
|July 20 - August 20&lt;br /&gt;
|You may have been conceived on a hot August day&lt;br /&gt;
|In most of the northern hemisphere there are many hot days in {{w|August}}.&lt;br /&gt;

|August&amp;amp;nbsp;21 - September&amp;amp;nbsp;21&lt;br /&gt;
|You may have been conceived as the leaves began to change&lt;br /&gt;
|In the northern part of the northern hemisphere the {{w|autumn}} starts at the end of this time period, so the leaves will begin to change color.&lt;br /&gt;
|-&lt;br /&gt;
|♋{{w|Cancer (astrology)|Cancer}}&lt;br /&gt;
|The&amp;amp;nbsp;Crab&lt;br /&gt;
|June 21 - July 21&lt;br /&gt;
|September 21 - October 21&lt;br /&gt;
|You may have been conceived by people trying on costumes&lt;br /&gt;
|This period ends 10 days before {{w|Halloween}}, so it is not unlikely that the people who conceived you (mom and dad) tried on their new costumes when they made you.&lt;br /&gt;
|-&lt;br /&gt;
|♌{{w|Leo (astrology)|Leo}}&lt;br /&gt;
|The&amp;amp;nbsp;Lion&lt;br /&gt;
|July 22 - August 23&lt;br /&gt;
|October 22 - November 23&lt;br /&gt;
|You may have been conceived during thanksgiving&lt;br /&gt;
|{{w|Thanksgiving}} is celebrated in the US on fourth Thursday of November, which for only two out of seven years will lie before the 23rd of November. However many people are born before 9 months so it is not unlikely for someone born as a Leo to be conceived on this day.&lt;br /&gt;
|-&lt;br /&gt;
|♍{{w|Virgo (astrology)|Virgo}}&lt;br /&gt;
|The&amp;amp;nbsp;Maiden&lt;br /&gt;

|December 22 - January 23&lt;br /&gt;
|You may have been conceived after a new year's eve party&lt;br /&gt;
|Since {{w|New Year's Eve}} always falls on December 31, and since the party goes on into the new year this fits with Libra. As it is very likely that people are together in a way that may lead to conception at this type of parties, there may even be rather more than a 30th part of the people that are Libra that are conceived at such a party.&lt;br /&gt;
