So I remembered the first year Biden became a "POTUS", we were all watching if he was going to give a SoU (and yes, technically in 2021 he gave a speech to a joint session of Congress, not a SoU). He ended up giving one on April 28.

Since he is doing his SoU again in March, I went back 40 years and searched when each SoU was given.

Every SoU prior to Biden has always been Jan or Feb (at least for past 40 years). 2 of Biden's has been in March, and one in April.

What is going on here?
