Frequently Asked Questions

How is age calculated exactly?

Age is calculated by counting complete years, months, and days between your birth date and the target date, accounting for varying month lengths and leap years.

Can I calculate my age on a future date?

Yes! Enter any future date to see how old you will be on that day. This is useful for planning retirement, milestones, or eligibility dates.

Why does age matter for HR and employment?

Age is important for determining eligibility for pensions, retirement benefits, age-related protections, and minimum age requirements for certain positions.

How does the calculator handle leap years?

The calculator correctly handles leap years. If you were born on February 29, your birthday is typically celebrated on February 28 or March 1 in non-leap years.

What is the difference between chronological and biological age?

Chronological age is the exact time since birth (what this calculator shows). Biological age refers to how old your body seems based on health markers and may differ from chronological age.

Can I calculate age for past dates?

Yes, you can enter any date after your birth date to see how old you were at that time. This is useful for historical records or verifying past ages.
