This comic takes the idea of {{w|advent calendar}}s to the extreme. It uses absurd and obscure ways to measure the amount of time until [[Randall]]'s new book [https://xkcd.com/whatif2 ''What if? 2''] is released, with esoteric units and esoteric numbers. See explanation of each day in the [[#Table of the calendar countdown|table below]]. Some concepts that appear multiple times throughout the calendar are:

This comic takes the idea of {{w|advent calendar}}s to the extreme. It uses absurd and obscure ways to measure the amount of time until [[Randall]]'s new book [https://xkcd.com/whatif2 ''What if? 2''] is released, with esoteric units and esoteric numbers.

Some concepts that appear multiple times throughout the calendar are:
  
 
* '''{{w|SI prefixes}}''', which can be applied to the beginning of a unit's name to multiply or divide the unit by powers of 10 or 1,000. This is standard for units like meters and grams, but is rarely applied to measurements of time other than when a unit of less than one second is needed, most commonly in various fields of science and engineering such as physics and electronics.

* The '''{{w|Gettysburg Address}}''', a famous speech delivered by U.S. president Abraham Lincoln in 1863, where he began by referring to the signing of the Declaration of Independence taking place "four score and seven years ago". A score is a dated term for the number 20, so "four score and seven" is equivalent to 87.

* A '''dog year''' is traditionally considered to be one-seventh the length of a normal human year, since a dog's overall lifespan is roughly one-seventh of a typical human's. The comic applies this to other units of time, such as minutes and months, each of which is also one-seventh the length of the standard unit. The number seven (traditionally a "lucky number") is also used in many of the numbers quoted in the calendar.

* Other comparative durations of time that are not normally or usefully applied to day-length multiples. At the top end, there is the age of the universe, at the other there is {{w|Planck units#Planck time|Planck-time}} – with entire durations of periods of human history and the time needed to watch popular TV/film franchises in-between – most of which require a non-trivial multiplier or divisor to bring them to the necessary scale required.

* A '''{{w|baker's dozen}}''' is 13, or one more than a normal dozen. Here, the "baker's" prefix can be applied to any unit by adding an extra one of its constituent parts, like an extra hour added to a day.

These are all interesting numbers because of their mathematical properties, but very impractical to use as arbitrary measurements of time because they have an endless series of non-repeating decimal digits.

The title text refers to the recursive time period on the final day before release, September 12, where the 99 Bottles of Beer song is sung 99 times, but with one less verse every time (so 99 verses the first time, 98 verses the second, 97, 96 ... 2 and 1 the last). If you don't stop when you reach N=0 bottles, the repetition never ends, so that time interval becomes infinite. He then calls it "The Other Song That Never Ends", comparing it to ''{{w|The Song That Never Ends}}''. That song is a repetitive children's song, which is specifically intended to go on forever. The difference is that the Beer song has a natural stopping point at 0, while ''The Song That Never Ends'' is [https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwiEz97RkZT5AhXpk4sKHRs8C2wQyCl6BAgLEAM&url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3Dxz6OGVCdov8&usg=AOvVaw2dI8Q_thXRfS6MUtq1NerU completely repetitive].

Take one down, pass it around, ''N-1'' bottles of beer on the wall." The entire song contains 99 verses. Randall apparently sings this rather slowly at around 72 bpm, taking about 13 seconds per verse. It can be done somewhat faster as [https://www.youtube.com/watch?v=FITjBet3dio shown here], where the 99 verses take less than 17.5 minutes for 10.6 second per verse. Then it would only take two months, or 61 days – 15 days too few.

The title text refers to the recursive time period on Sep 12. If you don't stop when you reach N=0 bottles, the repetition never ends, so that time interval becomes infinite. He likens it to {{w|The Song That Never Ends}}, another repetitive children's song, which is specifically intended to go on forever. The difference is that the Beer song has a natural stopping point at 0, while ''The Song That Never Ends'' is completely repetitive.

:[The comic is a calendar that counts down to a specific date, like a Christmas calendar starting on June 2nd and ending on September 13th (2022). Each day is represented with a large square and there are 12 weeks for a total of 84 days.  The days belonging to a particular month are surrounded by a thicker frame than between days from the same month. The first day of each month plus the very first day has the date given with three letters representing the month and the day number. This is written at the top right corner in a frame. All other days either only have the number for the day in the frame in the corner, or, if there are too much text on the day, no number is written. A single day has the number without the frame around it. The very last day notes what the countdown is for and there are three large stars places around the text, as well as smaller and larger dots, likely representing more stars in the entire field. All other days have text on all white background. The text represents a time that fits the time span from that day until the final day. The calendar begins on a Wednesday, and since the calendar week begins on a Sunday, there are three days missing to the left in the top row, and similarly four days are missing to the right in the bottom row as the last day is a Tuesday. Above the calendar is a large heading with a subheading below:]
