Frequently Asked Questions
Does it account for leap years correctly?
Yes - the calculation uses precise calendar-date math, so leap years are automatically factored into the years/months/days result.
Can I calculate someone's age as of a future or past date, not just today?
Yes - set the "as of" date to any date you need, useful for checking age eligibility as of an application deadline or event date.
What's the difference between the years/months/days result and the total days count?
The years/months/days breakdown is the calendar-style answer (e.g. "25 years, 3 months, 10 days"), while the total days figure is the same span expressed as one raw number, useful for milestone tracking.
