How Many Sleeps Until Avengers: Doomsday?
Avengers: Doomsday falls on Friday, December 18, 2026.
Avengers: Doomsday falls on Friday, December 18, 2026, which is 56 sleeps away. A sleep count is the number of nights still to come rather than the number of days, which is why it is the version adults reach for when the person asking is a child â and why it stays intuitive long after the day count stops meaning much.

How a sleep count works
The convention: one sleep means one night still to go. On the morning before, the answer is one. On the morning of the day itself, it is zero â you have run out of nights to sleep through. Because it tracks nights rather than 24-hour periods, the figure can read one higher than the day count for an event that lands in the morning.
