Questions
How is exact age calculated?
Whole years and months are counted on the calendar first, then the remaining days. Someone born on January 31 is one month old on the last day of February.
What about leap-day birthdays?
For people born on February 29, the birthday countdown uses February 28 in non-leap years.
Can I calculate age on a specific date?
Yes. Change "Age on this date" to any past or future date, for example to check an age limit on an application deadline.
