Formula
Age = full years between dates, plus leftover months and days (calendar-accurate, Western counting)
- • Count whole years from DOB to the target date.
- • Subtract those years, then count whole months; the remainder is days.
- • Month-end edge cases follow the common convention: Feb 28 → Mar 31 counts as 1 month + 3 days.
Pro tips
- • Change "Age at the Date of" to compute age at any historical or future date.
- • Total days uses calendar days, so it automatically accounts for leap years.
