	Also the statement that at 12am the sun isn't always at the zenith is a strong understatement; 12am is midnight and the sun would be closer to the nadir point than to the zenith point.

-: In old times, the hour was detected by observation of the position of the sun, or when the first three stars appeared in the night sky. During the first six hours of the day, the sun is seen in the eastern sky. At the sixth hour, the sun is always at its zenith in the sky, meaning, it is either directly overhead, or parallel (depending on the hemisphere). Those persons living in the Northern Hemisphere, the sun at noon time will appear overhead slightly towards the south, whereas for those living in the Southern Hemisphere, the sun at noon time will appear overhead slightly towards the north. From the 6th and a half hour to the 12th hour, the sun inclines towards the west, until it sets. The conclusion of a day at the end of twilight may slightly vary in minutes from place to place, depending on the elevation and the terrain. Typically, nightfall ushers in more quickly in the low-lying valleys, than it does on a high mountaintop.
-: The conventional Jewish way of calibrating the time of day is to reckon the "first hour" of the day with the rise of dawn (Hebrew: עמוד השחר‬), that is to say, approximately 72 minutes before sunrise, and the end of the day commencing shortly after sunset when the first three medium-size stars have appeared in the night sky. From the moment of sunset when the sun is no longer visible until the appearance of the first three medium-size stars is a unit of time called evening twilight (Hebrew: בין השמשות‬). In the Talmud, twilight is estimated at being the time that it takes a person to walk three quarters of a biblical mile (i.e. 1,500 cubits, insofar that a biblical mile is equal to 2,000 cubits). According to Maran's Shulhan Arukh, a man traverses a biblical mile in 18 minutes, meaning, one is able to walk three quarters of a mile in 13½ minutes. According to Maimonides, a man walks a biblical mile in 24 minutes, meaning, three quarters of a mile is done in 18 minutes. In Jewish law, the short period of dusk or twilight (from the moment the sun has disappeared over the horizon until the appearance of the first three stars) is a space of time whose designation is doubtful, partly considered day and partly considered night. When the first medium-size star appears in the night sky, it is still considered day; when the second star appears, it is an ambiguous case. When the third star appears, it is the beginning of the first hour of the night. Between the break of dawn and the first three medium-size stars that appear in the night sky there are always 12 hours.

-: In the Modern Age of astral science and of precise astronomical calculations, it is now possible to determine the length of the ever-changing hour by simple mathematics. To determine the length of each relative hour, one needs but simply know two variables: (a) the precise time of sunrise, and (b) the precise time of sunset. Since the actual day begins approximately 72 minutes before sunrise, and ends 13½ minutes after the sun has already set and can no longer be seen over the horizon (according to Maran), or 18 minutes (according to Maimonides), by collecting the total number of minutes in any given day and dividing the total number of minutes by 12, the dividend that one is left with is the number of minutes to each hour. In summer months, when the days are long, the length of each hour during daytime can be as much as 77 minutes or more, whereas the length of each hour during nighttime can be less than 42 minutes.

 :I wouldn't mind redefining the division of a day.  My problem would be with redefining the second, which would necessarily be a consequence of switching to metric time, and thus also the three base and nineteen derived SI units that depend on the current definition of s.

 :The length of a day isn't even constant.  If you had even divisions, the length of those divisions would be changing constantly.  "'It's been done that way for ages' is no excuse" is irrelevant reasoning.  A consistent system of time is needed (because good luck updating every computer constantly), and any one consistent method is as good as another because they can all be converted to each other (much like feet and meters can be).  The one that's been in use the longest tends to have the most support.  It's similar to how people don't have much of a reason to change keyboard layouts even though QWERTY or AZERTY or whatever regional preference may not actually be the most efficient.  [[Special:Contributions/172.69.210.34|172.69.210.34]] 23:52, 24 September 2018 (UTC)
