&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|first drafts}}&lt;br /&gt;
An {{w|Advent calendar}} is usually a means of celebrating the days before Christmas. Each day on the calendar is represented by a &amp;quot;door&amp;quot; (a flap of card), behind which is usually a picture related to the Christian nativity, a picture of commercial Christmas (eg a present), a small chocolate, or a small gift. This comic satirizes the concept by proposing such a calendar that would have one gift for each day one is anticipated to live. Such a calendar would be very morbid and existential. This is especially disturbing when given as a gift because it implies someone has put extensive thought into when the recipient will die.&lt;br /&gt;
&lt;br /&gt;
In [[Cueball|Cueball's]] case, assuming each square in the calendar represents one day, the wall he is facing is the entire present he received and the boxes just out of view follow the same pattern, the entire wall represents 16,800 days (a large grid of 12x20 smaller grids of 10x7 boxes: 12×20×10×7 = 16,800).  Commencing from 14 September, the sender of the gift assumes the recipient will live until 12 September 2061 i.e. just under 46 more years (10×7&amp;amp;times;12×20/365.25 = 45.99589). &lt;br /&gt;
&lt;br /&gt;
Assuming that Cueball is a male from the US, and according to American Official Social Security [http://www.ssa.gov/oact/STATS/table4c6.html Actuarial Life Table] for males, he is probably 31.9 years old [http://www.wolframalpha.com/input/?i=32*x+%2B+y+%3D+45.9%3B+31*x+%2B+y+%3D+46.83%3B+z*x+%2B+y+%3D+45.99589]. This would make [[Cueball]] almost the same age as [[Randall]], who was born October 17, 1984 making him 30.9 years old when he wrote this comic.&lt;br /&gt;
&lt;br /&gt;
The title text refers back to a standard advent calendar by saying that the Christmases are specially marked; on a traditional Advent calendar, only the 1st to the 24th of December have doors, however in recent times, Advent calendars often also include an additional door for the day after Advent, Christmas Day. Given that there are 46 Christmases on the calender, it may at first seem odd that it states that there are only a few dozen of these, when there are almost 4 dozens (48). However, this may be a reference to [[1070: Words for Small Sets]], which states that &amp;quot;a few&amp;quot; is between 2-5. The title text then gives Cueball between 24 and 60 Christmases left, so 46 years is within this range.&lt;br /&gt;
&lt;br /&gt;
A completely different advent calendar was mentioned in [[994: Advent Calendar]].&lt;br /&gt;
&lt;br /&gt;
Similar calendars have been mentioned in the blog ''Wait But Why'' in the 2014 post [http://waitbutwhy.com/2014/05/life-weeks.html Your Life in Weeks], and in equally geeky webcomic ''Abstruse Goose'', in the 2008 post [http://abstrusegoose.com/51 936 Little Blobs].&lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
[[File: Flipped.jpg|right|A flipped version of the comic]]&lt;br /&gt;
This comic is a continuation of [[1563: Synonym Movies]] with a new set of movie series.  As with the previous comic, the titles aren't always synonymous with the original (Indiana Jones as Professor Whip).&lt;br /&gt;
&lt;br /&gt;
This set includes Wandboy (Harry Potter), Puncher (Rocky), Tropical Boaters (Pirates of the Caribbean), and Professor Whip (Indiana Jones).&lt;br /&gt;
&lt;br /&gt;
The Wandboy series contains:&lt;br /&gt;
Wandboy and the Magic Rock (Harry Potter and the Sorcerer's Stone (or Philosopher's Stone in the UK))&lt;br /&gt;
Wandboy and the Hidden Room (Harry Potter and the Chamber of Secrets)&lt;br /&gt;
Wandboy and the Fugitive (Harry Potter and the Prisoner of Azkaban)&lt;br /&gt;
Wandboy and the Burning Cup (Harry Potter and the Goblet of Fire)&lt;br /&gt;
Wandboy and the Firebird Club (Harry Potter and the Order of the Phoenix)&lt;br /&gt;
Wandboy and the Book Owner (Harry Potter and the Half-Blood Prince)&lt;br /&gt;
Wandboy and the Magic Stuff (1/2) (Harry Potter and the Deathly Hallows Part 1)&lt;br /&gt;
Wandboy and the Magic Stuff (2/2) (Harry Potter and the Deathly Hallows Part 2)&lt;br /&gt;
&lt;br /&gt;
The Puncher series contains:&lt;br /&gt;
Puncher (Rocky)&lt;br /&gt;
Puncher II (Rocky II)&lt;br /&gt;
Puncher III (Rocky III)&lt;br /&gt;
Puncher IV (Rocky IV)&lt;br /&gt;
Puncher V (Rocky V)&lt;br /&gt;
Puncher Lastname (Rocky Balboa)&lt;br /&gt;
&lt;br /&gt;
The Tropical Boaters series contains:&lt;br /&gt;
Tropical Boaters: Spooky Boat (Pirates of the Caribbean: The Curse of the Black Pearl)&lt;br /&gt;
Tropical Boaters: Angry Wormface (Pirates of the Caribbean: Dead Man's Chest)&lt;br /&gt;
Tropical Boaters: Boats Everywhere (Pirates of the Caribbean: At World's End)&lt;br /&gt;
Tropical Boaters: Vitamin Water (Pirates of the Caribbean: On Stranger Tides)&lt;br /&gt;
&lt;br /&gt;
The Professor Whip series contains:&lt;br /&gt;
Professor Whip and the Box of God (Indiana Jones and the Raiders of the Lost Ark)&lt;br /&gt;
Professor Whip and the Scary Church (Indiana Jones and the Temple of Doom)&lt;br /&gt;
Professor Whip Looks for a Cup (Indiana Jones and the Last Crusade)&lt;br /&gt;
Professor Whip is in Another Movie (Indiana Jones and the Kingdom of the Crystal Skull)&lt;br /&gt;
&lt;br /&gt;
The &amp;quot;is in Another Movie&amp;quot; title differs from the other titles in that it does not reference the plot of the movie.  The more dismissive reference may be due to Indiana Jones and the Kingdom of the Crystal Skull being poorly received by fans of the series.&lt;br /&gt;
&lt;br /&gt;
The title text is a reference to the TV series A Game of Thrones, based on the book series A Song of Ice and Fire.&lt;br /&gt;
The Hot and Cold music series contains:&lt;br /&gt;
Fun With Chairs (A Game of Thrones)&lt;br /&gt;
Royal Rumble (A Clash of Kings)&lt;br /&gt;
Knife Blizzard (A Storm of Swords)&lt;br /&gt;
Breakfast for Birds (A Feast for Crows)&lt;br /&gt;
Samba Serpents (A Dance with Dragons)&lt;br /&gt;
&lt;br /&gt;
