Here is a proposed release schedule for 22.0, the next major release of Bitcoin Core. Like for previous major releases I've aimed for a release 6 months after the last (#18947).

It is based on the projected release date for 0.21.0, so it is possible these move forward if there is slippage.

There was a rename from 0.22.0 to 22.0; see #20223.
