21st birthday ideas
Twenty-one: the last big age milestone of growing up. Traditions, party ideas, gifts, toasts and card messages for turning 21.
What turning 21 means
Turning 21 feels like the final step into full adulthood in the US. It is the legal drinking age in every state, so for many people it marks the first time they can order a drink at a restaurant or toast with real champagne. Friends often plan a big night out, while families see it as a sign their child is ready to stand on their own. The best 21st parties focus on the people, not just the drinks.
