If I ask my favorite search engine "when will Ubuntu 21.04 be released?" it returns an accurate answer and source for that answer. Also, the release numbering quite famously follows a YY.MM format -- 04 refers to April. – user535733 Feb 20 '21 at 16:40

21.04 means the 2021-April release.
As all standard Ubuntu releases use the year.month format, it's easy to know when a release came out, and when future releases will come out.
eg.
- 18.04 means the 2018-April release.
- 20.04 means the 2020-April release.
- 20.10 means the 2020-October release.
so
- 21.04 will be the 2021-April release (it's referred to as hirsute or hirsute hippo until release time when it will become 21.04 as all Ubuntu development releases are)
Specialist Releases use year format
Ubuntu also have specialist releases that use the year format, eg. Ubuntu Core 18 meaning the 2018 release, Ubuntu Core 20 meaning the 2020 release, but these are snap only and intended for device, appliance and cloud use, so not general server or desktop intended purposes.
Releases are April & October with one exception
With one minor exception, Ubuntu releases are usually the April and October of each year. The first LTS was in 2006-June, ie. late and it was thus called Ubuntu 6.06 LTS (the only non-April LTS release).
Predicting date of future releases even if no schedule exists
Releases are always on a Thursday, scheduled to not be the last thursday of the month (3rd usually) as it provides a week to push the schedule back if necessary and keep it in the month.
For 21.04/hirsute hippo, the schedule can be found at
https://discourse.ubuntu.com/t/hirsute-hippo-release-schedule/18539
Knowing when a release reaches End-of-Support easier too
Knowing when a release reaches end-of-life is also made easier. Non LTS (long-term-support) releases have 9 months of supported life, so you can add 9 to the month (20.10 + 9 = 21.07 EOL) and know when you need to release-upgrade to the next release. Ubuntu LTS releases have 5 years of standard support, where as flavors have only 3 years. Standard support for LTS releases can be extended via ESM.

In the predicting the date, if the month has 5 thursdays, it's usually the 4th thursday. I could have worded that differently (2nd last thursday of month), but I felt 3rd thursday was better as most months have 4 thursdays... Better to always check the schedule anyway (20.04.2 release date got moved at least twice) so I didn't provide the date by choice. – guiverc Feb 20 '21 at 22:44

Upvoting because this is true of course but I'm of the mindset there should be a release when something is new (and stable!) not a release just because the calendar demands something. – WinEunuuchs2Unix Feb 21 '21 at 01:01

@WinEunuuchs2Unix Yeah I love Debian too :) (the stable applies there, the 'new' maybe not so much, they're somewhat calendar based too) – guiverc Feb 21 '21 at 01:02
