Talk:3019: Advent Calendar Advent Calendar

Would this basically be triangle numbers? So on Christmas Eve you would open 300 windows?Tommyds (talk) 16:01, 2 December 2024 (UTC)

Yes and no. It's not 12 days of Christmas (as mentioned in the title text), so only the overall number of gifts are a triangle number; you open 30 windows on Christmas Day. The 12 days ref is key as the song generates more gifts if taken literally even in 12 days -- 78 on the last day, 66 on the previous day, etc, for a total of 364.

If you are allowed to open newly discovered missed windows each day, it’s 50 windows the last day (the 1 “25” top-window, 25 “25” sub-windows, 24 non-“25” sub-windows in the “25” top-window). Any reasonable interpretation I can think of results in a partial sum of that “1 + 25 + 24” (don’t know how you get 30). Ltrlg (talk) 16:58, 2 December 2024 (UTC)

Notice that this year The Advent calendars are correct. Normally, Advent calendars start at the 1st of December even if the Advent starts at a different day. But this year the Advent also starts at the 1st of December. 162.158.172.40 16:55, 2 December 2024 (UTC)

Donald Knuth wrote a paper for April 1984 Communications of the ACM that included an analysis of the complexity of 12 Days of Christmas. It's in the CACM archive https://dl.acm.org/doi/pdf/10.1145/358027.358042.
