Overwatch Season 21 End Date: When Does Season 21 End?

The end of Overwatch's season 21 is quickly approaching. Players are running out of time to change their SR for the season.
Season 21 started at the beginning of March, which also marked the beginning of the weekly hero bans. The way that the hero bans work has changed throughout the season. Most recently, the hero bans have changed to only apply to high ranked games.
"Every week when players log into Overwatch, it should feel fresh and different."

Overwatch Season 21 End Date: When Does Season 21 End?
Overwatch competitive season 21 is scheduled to end about May 7, based on the length of previous seasons. There is currently no official end time, but it will likely be sometime in the afternoon.
The bad news is that the currently banned heroes, Reinhardt, Reaper, Ashe, and Brigitte, will remain banned until the end of the season. The good news is that the bans for this week are only in Master and Grandmaster games.
