Here is a proposed release schedule for 0.21.0, the next major release of Bitcoin Core. Like for previous major releases I've aimed for a release 6 months after the last (#17432).

2020-10-01 ✔️

• Open Transifex translations for 0.21
• Soft translation string freeze (no large or unnecessary string changes until release)
• Finalize and close translations for 0.19

2020-10-15 ✔️

• Feature freeze (bug fixes only until release)
• Translation string freeze (no more source language changes until release)

2020-11-01 ✔️

• Split off 0.21 branch from master
• Start RC cycle, tag and release 0.21.0rc1
• Start merging for 0.22 on master branch

2021-01-14 ✔️

• Release 0.21.0 final

If any specific dates or timeframes are a problem for you, let me know.
