FAQ
How is age calculated?
Full years, then leftover months, then days, using local calendar dates — not UTC.
Can I age to a date that is not today?
Yes. Change “On this date”.
What if the birthday has not happened this year?
Years count only completed birthdays. Months and days fill the remainder.
