TWO AGES.ONE MASSIVENUMBER.

You're 38. Your mate's 42. Together you're 80.2 years old — and that total climbs every single day. We work out the exact date it hits 100. It won't be either of your birthdays. It'll be a random Tuesday that belongs to the two of you.

✦ WHO'S CELEBRATING? ✦

Two people minimum, four maximum. Names only show up in your results — nothing is saved or sent anywhere.

★ CHASING A NUMBER? optional

★ LOCKED IN: 100 YEARS

Takes about half a second. Then start planning.

✦ EVERY MILESTONE AHEAD ✦

These are the exact days your combined total crosses each number.

SO… HOW DO YOU CELEBRATE A NUMBER LIKE THAT?

Here's what people actually do with theirs.

✦ HOW IT WORKS ✦

THREE TAPS TO YOUR
NEXT BIG EXCUSE

1

DROP IN THE BIRTHDAYS

You and a mate, you and your partner, the whole family. Two to four people — no account, no email, nothing to install.

2

WE DO THE MATHS

Your age isn't a whole number — right now you're 38.4 years old, not 38. We add everyone's exact age together and solve for the precise day the total crosses 100 (or 150, or 250). It lands on an ordinary day that isn't anybody's birthday.

3

CLAIM THE DATE

Copy it, stick it in the calendar, send it round the group chat. Nobody else on earth shares that date — it only exists because of your two birthdays.

YOUR NEXT
MILESTONE IS
ALREADY BOOKED

You just don't know the date yet. Takes ten seconds to find out.
