December holidays & observances

December sits in the part of the year when calendars start to fill up — not just with the well-known holidays, but with the smaller observances that often go unmarked. The list below covers every December-dated occasion in CardVerse, from major faith holidays and national days to lesser-known awareness days and cultural festivals. If you’re planning ahead, this is the page to bookmark.

For non-dated occasions in this season — birthdays, sympathies, friendship cards, get-wells — head to the categories index or the complete alphabetical list.
