The Unofficial Tumblr Calendar

For this calendar at least, a Tumblr Holiday must:

Have a specific, single date (not a week or a month)

If it is from a fandom, must escape containment regularly

Must be actively celebrated on Tumblr with popular or frequent posts

Must not be a common holiday elsewhere (We don't do Christmas or Christmas Eve, but we do Christmas Adam)

Must not be generated by a corporate account (be it Denny's weirdness or Toyotathon)

If possible, should be represented by an accessible post with alt text or a description of images

Exceptions to these rules will be made if they tickle my fancy for Reasons.

When you submit, please consider adding links to specific posts!

And when you post your own, tag it #makeaterriblecomicday2026!

All this week, from 6/20/26 through 6/29/26, it's Palindrome Date time!

And the first day of the week, 6/20/2026, is an even better/more complete palindrome!

Why not use the day to reflect?

One week 'til Make a Terrible Comic Day!

This one's a self-indulgent one, my friends.

My birthday, June 2nd, is officially Bad Art Release day. On that day, you make and or post art that you don't think should be posted.

Grab some Dollar Store crayons, doodle a bunny. That sketch you've been noodling with for like 200 hours and you just can't get it right? Post it anyway.

Got some incredibly self-indulgent recordings of you singing your favorite song? Throw that shit on soundcloud.

Doesn't matter what it is. Doesn't matter if it's ready for prime time or safe for work. The journey is the destination, baby. If you were having fun and or trying to say something, it counts.

Please create bad art, or release the art you think is bad into the world. This is your permission to post ANYTHING, to spend time making ANYTHING, to try something new or let go of something old.
