Therianthropy Day is Wednesday, November 5, 2025
Therianthropy Day is on the first full moon of November each year. This year, it will be on Wednesday, November 5, 2025. According to NASA, this will happen to be a supermoon, which means it might be slightly brighter than usual.
Why that date, and what is the history of that holiday?
Therianthropy Day commemorates the first Howl, which was held 31 years ago in November 1994. A Howl is when therians meet up together in person. That was a year after the first therians started to meet up together online in November 1993. Therians first proposed commemorating it as a holiday on that date in 1996, in a conversation thread you can still see here. Based on that history, in 2016, Muninn the Raven proposed observing it as Therianthropy Day, though the first posts and community poll about it attracted little attention. I think the holiday finally really caught on in 2021, when I first saw many therians posting on social media about fun things they were doing for it.
What are therians, anyway?
If therianthropy is a new idea to you, or you want to explain it to others who are unfamiliar with it, this essay is a quick and easy introduction to it. It’s available in several languages, and the project welcomes more translations!

What can we do for Therianthropy Day?
Therians have been celebrating it by wearing gear (for example, a necklace with the therian symbol, a tail, or clothes with pictures of their species), meeting up with their therian friends, and howling at the moon. (If you're meeting in person for the first time, stay safe!)
If you're not so open about your therianthropy, you can indulge in some quiet reflection by yourself with a guided meditation and self care.
Enjoy more than 40 games, zines, and other creations about therianthropy from this hand-curated itch.io collection.
Put on some jams that the Alterhuman Music blog tagged as therian, many composed by self-described therian musicians.
Cook a recipe inspired by what your species of animal side would eat. (Even if you're not a dragon, I recommend this presentation as an introduction to this practice because of the advice about how to adapt the sometimes strange foods that you may find species-affirming so that they'll be safe and delicious!)
Create something about your therianthropy! Draw a comic, write a zine, compose a song, design a game, craft some gear, use whatever creative medium you like. Everyone in our community takes part in creating it, it's all very much about DIY and self-expression.
Are there days for other sorts of alterhumans too?
There are. Alterhuman Day commemorates when Lio of the Crossroads System coined that word on September 26, 2014. Otherkin Day is on July 9, commemorating when the word was coined in 1990, though the word’s origin is a little more complicated than that. Plural Pride Day is the third Saturday of July, and Plural Acceptance Week is that week.
