About Bonus Birthday

Annual birthdays are lovely, but they skip over some genuinely astonishing round numbers. Ten thousand days of life. A billion seconds. Half a million hours. These are real moments in a life — and most of us never know they are coming.

Bonus Birthday exists to fix that. Enter your date of birth and we will show you every bonus birthday still ahead of you, calculate the exact date for each one, and help you celebrate with a free downloadable card, a calendar reminder, and a share that is entirely under your control.

What we believe

• • Milestones should be calculated, not approximated.
• • Your date of birth is yours — it stays in your browser.
• • Celebrating should be easy, free and cheerful.
• • A good excuse for cake is never wasted.

What we do not do

• • We do not store your date of birth or name.
• • We do not predict lifespan or count down the time you have left.
• • We do not require an account.
