THL Observances Calendar
This is a list of observances relevant to, invented by, or patterns of dates noticed by, THL.
It's broken up into rigid dates, and circumstantial dates.
Rigid dates are always November 11 regardless of the day of the week.
Circumstantial dates will vary based on some variety of proximity or calculation, such as the first Monday of each month.
Observing either of the Rigid dates or Circumstantial dates, or both, are options available.
As a point of trivia, the Monthly Addition Day was the first day which sparked the idea of having the THL Observances Calendar.
Year-Circumstantial
- Monthly Addition Day
- When the month and the date add up to the last 2 numbers of the year.
- Ex. 1+23=24 for January 23, 2024, or May 26, 2031. Not possible to celebrate after December 31, 2043, until January 1, 2102. Whenever you first realize you've added anything up on this day (including counting by any increment), simply whisper, “cha-ching.” Only needs to be said once for the whole day, to observe it.
