The issue is a great deal of the rest of the world don't do this, so you need to decide whether to apply best-guess heuristics to parse it or decide that it's a typo ("ah there's not 22 months, so maybe it's the 22nd of February or someone fat-fingered the 2nd of February...?").

In this case you can lookup Slack outages to disambiguate it, but the frustration here - and I share it - is directed at the stubborn refusal to use a standard format that the reest of the world has agreed upon.
