Frequently Asked Questions
What's a good message for someone turning 100?
Something that honors the scale of the milestone — a century of life — rather than a standard birthday line works best for an occasion this rare.
What's traditionally done to celebrate a 100th birthday?
Many families organize a larger gathering than usual, and some request a formal birthday greeting from a head of state or local official, a tradition in several countries.
Is it okay to keep the message short for such a big milestone?
Yes — a short, sincere message can carry just as much weight as a long one, especially when paired with time spent together in person.
