FAQ
- How is the age counted?
- Whole years, then whole months, then the remaining days. If the day of the month hasn't arrived yet, the month count steps back.
- What if the as-of date is before the birthday?
- There's no age to show. The later date has to be the as-of date.
- What about 29 February?
- Age uses calendar months and days. A next birthday that falls in a non-leap year is shown as 28 February.
- Does this include the time of day?
- No. Both dates are treated as calendar days in your local timezone.
