Very stupid question about my drivers license

I turned 21 back in August but my license doesn’t expire until August of 2021, so I haven’t really rushed into going to renew it just because I’ve been so busy with other stuff. Since it doesn’t expire until 2021 I can like.. still use it to go out right. I haven’t been out really since I turned 21 lmao but i was just googling hours of my DMV near where I live and just got into a whole bunch of info saying I must renew it 60 days after turning 21. This is probably a very dumb question.
