When Is Dune: Part Three?

Dune: Part Three 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 Dune: Part Three

Denis Villeneuve's adaptation of Dune Messiah concludes the trilogy, in theaters and IMAX Friday, December 18, 2026 — with a three-week IMAX exclusivity window over Avengers: Doomsday.

Same day as Avengers: Doomsday. One weekend, two event films, one very full cinema. The live counter above runs to the release/event date worldwide (local time zones may shift availability by hours).

Dune: Part Three opens head-to-head with Avengers: Doomsday on the same day — the showdown fans already call 'Dunesday'. Two premieres, one counter: which side of December 18 are you on?
