Fans make calendars featuring their favorite sources that can contain either fanart or just be designed with screencaps. Some also contain poetry or even longer fanfic. They may be distributed online (e.g. as pdf file), though in the past they were more often printed by zine publishers, sometimes also associated with a zine series, such as the case with the Interphase (calendar).
Unlike official merchandise calendars, they don't necessarily start on a New Year.
Another fannish calendar is the online Advent Calendar.
