Age calculator
How the age is counted
- Whole calendar days are counted between the birth date and the date you are measuring to.
- Years, months and days follow real month lengths. From 1 January to 31 January is thirty days rather than a month; from 1 January to 1 February is one month.
- The arithmetic runs in your device's own time zone, not in Coordinated Universal Time.
- A birth time is only needed for the countdown to the next birthday and the heartbeat estimate; the age itself is a matter of dates.

What on this page is an estimate, and what is not
- The heartbeat count assumes about 72 beats a minute at rest, which is a population average rather than your own pulse.
- Zodiac signs and birthstones are Western lists, not a Pakistani standard or any authority on either subject.
- Weeks, days, hours and minutes are measured from elapsed time while years, months and days come from the calendar, so the two sets are not expected to reconcile exactly.
- A 29 February birthday is counted as falling on 1 March in a year without a leap day.
Questions people ask about this figure
Why was the answer once a day short?
The calculation used to read the day from UTC, and Pakistan's day begins five hours later. That made the result one day short through every Pakistani morning, and one year short on a birthday. It now reads your local calendar, and a test holds that behaviour in place.
Do leap years count?
Yes. Days are counted, and 29 February is a day, so it is included.
Can this settle a legal age question?
No. Legal age follows the date printed on your official documents, not a website's arithmetic.
Age is worked out in your device's time zone; confirm a legal age against your official documents.
