The December calendar is coming soon, but in the meantime here is a picture I drew a few years ago for patrons on patreon.com/tanaudel, designed to double as a printable advent calendar, as there are 25 birds to colour in.
There is also a 12-day calendar here, if you’re doing Twelfth Night (or starting late).
Note re support: This picture — and a lot of the art that happens here — is made possible by patrons on Patreon.com. If you’d like to see more and/or if you like supporting the arts, you can do that (and get it and other behind-the-scenes things early) at patreon.com/tanaudel (starts at US$1/month!); there is also a tip jar at paypal.me/tanaudel.
