My husband and I have the same birthday (what are the odds?). Usually we put the kids with friends and go out to a nice dinner together, and maybe a movie or show. We have also gone out to dinner with groups of friends, and one year we went to a college football game (for you, maybe baseball, or...?). I think it's really fun to celebrate our birthday together, but my husband jokingly says he never gets to feel like it's "his" special day.
This year, I am going to try and get a side-by-side couples massage at a spa. Maybe that will help my husband feel like it's "his" special day, too, with some pampering.
I'm curious to see what answers you get! I will learn from those, I'm sure.
Happy birthday(s)!
