Frequently asked questions
How is the exact age calculated?
Exact age starts at 0 in the year you are born and increases by one each time your birthday passes. If this year's birthday hasn't come yet, it is one or two years less than the counting age.
What are counting age and year age?
Counting age starts at 1 at birth and adds a year each New Year, while year age is the current year minus the birth year.
Is the date of birth I enter sent to a server?
No. All calculations happen inside your browser, and the values you enter are not sent to any external server.
