When we were kids, we counted down the days to our birthdays, but these days, birthdays have a way of creeping up on us. Unless you’re celebrating a milestone year and someone is throwing you a party, it may seem like a ton of effort to plan things to do on your birthday. And to be honest, some years you really don’t want a party (and don’t want to feel guilted into having one). So if that means you want to take a bath and go to bed early, go for it. If you want to spend a weekend away with your girls, round up the troops and book a hotel.To make your birthday planning a cinch, we’ve rounded up some of the best things to do on your birthday—from going out, to staying in, and everything in between.
