When Is Avengers: Doomsday?

Avengers: Doomsday falls on Friday, December 18, 2026 — a Friday. That is 56 days from today. The date is confirmed, so the only thing that moves is the countdown itself.

Why the day of the week moves

A date advances by one weekday each year, because 365 days is 52 weeks plus one day. In a leap year it advances by two, which is why the weekday occasionally jumps. Over the six years in the table above you can watch both patterns: the single-step years and the leap-year double step.

This matters more than it sounds if you are planning around a weekend. An event that lands on a Saturday this year may fall midweek in two years' time, which changes everything from travel to time off.

About Avengers: Doomsday

The MCU's biggest assembly ever — Avengers, X-Men, Fantastic Four and Thunderbolts against Robert Downey Jr.'s Doctor Doom — directed by the Russo brothers, in theaters Friday, December 18, 2026 (165 minutes).

It shares its release date with Dune: Part Three — a box-office showdown the internet has already named 'Dunesday'. The live counter above runs to the release/event date worldwide (local time zones may shift availability by hours).

It's the endgame of the Multiverse Saga's Phase Six — and no, it's not the last Avengers movie: Secret Wars follows in 2027. Bookmark this page and watch the seconds fall toward the biggest premiere night of the year.
