18th birthday ideas
Officially an adult: first votes, big plans and a world of choices. Traditions, party ideas, gifts, toasts and card messages for turning 18.
What turning 18 means
Turning 18 is the birthday most people think of as the start of adulthood. In most states, an 18 year old is a legal adult who can vote, sign a lease or contract, and be called for jury duty. It often lands near high school graduation, so the year is full of goodbyes and fresh starts. Parents usually feel proud and a little teary, while the birthday person feels a door swinging open to a life they get to shape themselves.
