January 8 is the next meetup of the SF Bay Interactive Fiction Meetup. [Edited: originally it was listed as Jan 1, but it’s been moved to avoid holiday clashes.]
[Edited to add:] The next meetup for the Seattle/Tacoma IF group will be on January 9.
Running for a week starting January 1 on itch is the Historically Accurate Game Jam. This isn’t specifically an IF competition, and games of all types are welcome, as long as they’re written in a week and address the chosen time period or event of the jam. If you’ve had a craving to contribute to the tradition of historically-themed IF, though, this might be a place to do it.
