Calculate your exact age — down to the day
An age calculator does more than count birthdays. It works out the precise gap between your date of birth and any reference date in completed years, months and days, and converts that span into weeks, days and hours.
Australians use age figures every day — for superannuation preservation rules, age-pension eligibility, ATAR/HSC year groups, drivers' licence stages, and visa and insurance underwriting. A small miscount can shift you across an eligibility threshold.
Calendar-aware age difference
years = floor((asOf − dob) in years, calendar-adjusted) months = remaining whole months after years days = remaining days after months total_days = (asOf − dob) in days, leap-year aware
We walk the calendar (not 365.25-day approximations), so February 29, end-of-month rollovers and leap years are exact.
Born 15 June 1995, age on 7 May 2026
- From 15 Jun 1995 to 15 Jun 2025 → 30 completed years.
- From 15 Jun 2025 to 15 Apr 2026 → 10 completed months.
- From 15 Apr 2026 to 7 May 2026 → 22 days.
- Total span = 11,284 days = 1,612 weeks + 0 days.
| Threshold | Why the day counts |
|---|---|
| Super preservation age | Born after 1 Jul 1964 → 60. Access depends on the day you were born. |
| Age Pension | Currently 67 — Services Australia uses your DOB to the day. |
| P-plate progression (NSW/VIC) | Minimum hold periods are counted in calendar days. |
| Insurance bands | Premiums often step up on the policy renewal after a birthday. |
| ATAR cohort | Year 12 cohorts use age-on-30-June rules in some states. |
- •Use the 'as of' field for future planning (e.g. age at retirement).
- •For legal documents, always confirm against the original birth certificate.
- •Hours and minutes are useful for newborns — set 'as of' to today for a live counter.
