Typical reasons to use the age calculator

Know your exact age

Down to the day, not just the year.

Plan an anniversary

Days until the next milestone from a date.

Age eligibility check

18+, retirement, scheme cutoffs.

Days between two dates

Between any two dates — not only birthdays.

Heads up

Common pitfalls

Wrong timezone

Birthdays are date-based, not instant-based. Crossing timezones shouldn’t flip the day — pick the locale of birth.

Mixing ‘months’ and ‘4 weeks’

A month isn’t always 4 weeks. Use months for age, weeks for short intervals.

Age vs birthday logic

You ‘turn’ X on your birthday. Until then, you’re still X − 1 even if months are close.

Leap-day birthdays

Feb 29 birthdays usually celebrate on Feb 28 / Mar 1 in non-leap years. The tool reports calendar-accurate age either way.
