Age calculator
Enter a date of birth and this reads back the age in calendar years, months and days, plus a running total in seconds. Left on "now", the reading keeps ticking; set a fixed reference date instead and it becomes a one-off calculation as of that moment.
Worth noticing
- The calendar figure ("27 years, 4 months, 12 days") accounts for actual month lengths and leap years — it is not an average, so it will not drift the way dividing total days by 30.4 would.
- A birth date after the reference date is refused rather than shown as a negative age.
