Frequently asked questions
How is the exact age calculated?
Whole months since birth are counted first, then the remaining days. The result follows the calendar: February has 28 or 29 days.
What if I was born on 29 February?
In years without a 29 February, the birthday is counted on 28 February, the last day of the month.
What is my 10,000th day?
The day you will have lived 10,000 days, at about 27 years and 4½ months. The page gives the next milestone: 5,000, 10,000, 15,000 days…
Is my date of birth stored?
No: the calculation runs on your device. It is kept on it only if you tick the box.
