One pet peeve about dates

This is probably just my ADHD talking and I know people only do it because they wanna be thorough. But there's just this thing that irks me.

So you're watching a YouTube video and some important person comes up. Like a scientist that discovered something. The presented tells us their birthday, because it may be important in relation to their discovery.

But why do I need to hear the whole date? Isn't year enough, or month at most? Especially if the presenter says the date slowly, with reverence, I almost tune out by the time the year comes up, or I try to remember the whole date and fail anyway.

Just tell us the actual important part of the date, please. Or don't even mention it if it's not relevant.
