Frequently Asked Questions
How is the exact age calculated?
Age is calculated from the exact birthdate to the current moment (or a custom target date). Months are counted calendar-accurately, accounting for different month lengths and leap years.
What is 'Unix epoch age'?
Unix epoch age is the number of seconds elapsed since your birthdate — the same unit used in Unix timestamps. Useful for querying databases or APIs that store timestamps as Unix time.
