Birthdays are about more than ticking another year off the calendar.

They’re a reason to reconnect, relax, and try something yourself, whatever your guest list size or budget.

With a little planning and creativity, your summer birthday party can feel as joyful as a favorite holiday.

Whether you’re drawn to the classic backyard BBQ, a chic al fresco dinner, or a themed indoor celebration, summer gives you every reason to say yes.

Pick your favorite idea, send out the invites, and treat yourself to a celebration you (and your friends) will actually want to repeat.

Happy Celebrating!
