1.20.1992:

In a 2012 Tumblr post, comedian Donovan Strain used the song’s lyrics to determine that the titular “Good Day” likely occurred on January 20, 1992.[10] Strain wrote that this date was “the only day where Yo! MTV Raps was on air, it was a clear and smogless day in Los Angeles, beepers or pagers were commercially sold, Lakers beat the SuperSonics, and Ice Cube had no filming commitments”.

It was a good day unless you’re a lemmitor who hates good music and needs to downvote everything
