It’s super annoying, but even though they’re all airing at the same time, Picard, Lower Decks, and Prodigy all take place at slightly different times. At least they’re consistent with TNG stardates, where 41000 is 2364, and each 1000 stardates equals one Earth year, so you can get a year from a captain’s log entry. From Memory Alpha:

Lower Decks: 2380-2382

Prodigy: 2383–2385

Picard: 2399-2341 (Ignoring flashbacks)

I miss the TNG / DS9 / VOY era, when shows airing concurrently all take place at the same time.
