Frequently asked questions
How is the countdown calculated?
We take your birth date, set the year to the current year (or next year if your birthday has already passed), and subtract today's date.
What if my birthday is today?
The card displays "Today!" so you don't miss it.
What age will I be turning?
The result card shows the age you will turn on your next birthday.
Can I use this for someone else?
Yes. Enter any birth date in the past and the calculator returns that person's next birthday.
