The great Seattle festival will take place May 17-June 10, 2018. Early deadline is October 6 and late deadline is January 5. Note films must be WA state premieres. Submission fees used to be waived for WA state filmmakers, but it is unclear if this is still the case. More info here.

Anifilm is an awesome international animation festival in the beautiful old town of Trebon, a few hours south of Prague in the Czech Republic. It occurs in May each year. The deadline for film submission is January 15th, 2018!
They also host the Visegrad Animation Forum, a pitching event for European short films and TV series, that is very interesting to observe. I wrote up a review of Anifilm on the Edge of Frame blog last year, read it for more details.
