100th birthday ideas

A full century, and a celebration for the history books. Traditions, party ideas, gifts, toasts and card messages for turning 100.

What turning 100 means

Turning 100 makes someone a centenarian, and it is one of the most moving birthdays a family can celebrate. A full century means living through a hundred years of change, and every guest at the party is part of that story. In Japan, the 100th is called hyakuju. In the UK, the King sends a message, and in the US the White House will send a greeting if you request it ahead of time. It is a day to honor a whole life.
