Introducing the Next Birthday Countdown — Days Until Your Big Day

“When’s your birthday again?” is easy to answer. “How many days until your birthday?” is surprisingly easy to get wrong — months are different lengths, leap years sneak in an extra day, and you can be off by a day or two without realising. The new Next Birthday Countdown answers it exactly.

What it does

• Days until your next birthday, counted from today.
• Weeks-and-days and approximate-months breakdowns.
• Turning age and current age.
• Weekday the birthday falls on — handy before you book anything.
• Leap-day safe — 29 February folds to 28 February in common years.

Why it matters

A countdown is really about lead time. Knowing you have 42 days rather than “sometime next month” tells you whether to relax or start planning. To understand the date math behind it — including the leap-day quirk — read our guide to how birthday countdowns work, and check your exact current age with the Age Calculator.

Free, and private

The Next Birthday Countdown is free and runs entirely in your browser — your date of birth is never uploaded or stored. A future Pro upgrade is planned for saving everyone’s birthdays and sending reminders, but the single countdown stays free forever.
