my birthday often falls the week of thanksgiving, so i usually just take the day off as a "extending the long weekend" if i don't already get it off. since i moved to the west coast ~3 years ago and most of my friends and family are back in new york, every year on my birthday in the morning i make sure to:
1. respond to every single birthday text i got, and if possible hop on a quick call with as many people as i can. basically just a gratitude practice of "hey as i've gotten older i've not only developed meaningful relationships, i've also held onto a lot of meaningful relationships."
2. eat breakfast out; i think my birthday breakfast for the last two years has been Oddfellows Café + Bar (oddfellowscafe.com), but taking the time to have an extra special solo (or with my partner) breakfast keeps the scaries at bay for at least a couple hours
3. going shopping for a birthday gift for myself in person so i have something to open when i get home.
after that it's pretty much just about having a couple extra things to do during my day like trying a new restaurant / going to a favorite for lunch, running a "fun" errand like dropping off film to get scanned, and then meeting local friends for either dinner out and / or cake and games back at my apartment, etc.
having something where i can look back and feel like i did something is all i'm looking for; i think through my late teens / early twenties i put a lot of emphasis on wanting my my birthday to feel "special" which meant it was doomed to not be "special" enough. since pivoting to having fun my birthday has felt a lot more special since it's just different from the monotony of a normal day, and there wasn't any extra pressure on it
