Frequently Asked Questions
How is the age calculated?
Age is the difference between the birth date and today, adjusted so that partial months and days are counted correctly, including leap years.
How do you handle 29 February birthdays?
In years without a 29 February, the birthday is treated as 28 February for the purpose of counting down to the next birthday.
Is my date of birth stored anywhere?
No. The calculation runs in your browser and nothing is sent to a server.
