Age Calculator
Calculate your exact age in years, months, and days from your birth date.
About the Age Calculator
The age calculator computes your exact age in years, months and days from your birth date to today — the precise figure needed for government forms, school admissions, passport applications, examinations and employment records in Pakistan, where age is frequently a formal eligibility criterion.
The calculation correctly handles the calendar's irregularities: the day count borrows from the previous month when today's date is earlier than the birth date, and months borrow from the year in the same way. This is exactly how a careful human calculation would work, but done instantly and without arithmetic slips.
Beyond documents, an exact age matters for health and development: paediatricians track children against age-based growth charts, vaccine schedules depend on precise age, and adult health screenings like diabetes checks have age cut-offs. The day-level precision of this calculator supports those decisions.
The calculator also makes quick work of common questions: how old will a child be when school starts, when will a person reach a particular age, or what was someone's age at a historical event. Enter the birth date and the current date is used automatically, giving the exact age at this moment.
For legal purposes in Pakistan — CNIC applications, retirement calculations, or age-of-majority questions — the date of birth recorded on official documents is the reference. Use those documents' dates to avoid discrepancies between records and this calculation.

Frequently Asked Questions
How is my exact age calculated?
The calculator compares today's date with your birth date and breaks the difference into full years, remaining months and remaining days, correctly handling shorter months.
How is exact age calculated?
The calculator subtracts the birth date from today's date, borrowing days from months and months from years where needed, so the result is the precise number of full years, months and days.
What age do I need for a CNIC in Pakistan?
The Computerised National Identity Card (CNIC) is issued at age 18. A National Identity Card for Overseas Pakistanis (NICOP) and a Smart National Identity Card follow the same age rule.
Is there a difference between biological and chronological age?
Chronological age is the calendar age this calculator gives. Biological age reflects how your body has aged relative to your health and lifestyle — it can be younger or older than your calendar age.
