How is age counted?
Age counts completed years. You turn one year older on your birthday. For a birthday on 15 June, someone born in 1995 is 30 on 14 June 2026 and 31 on 15 June 2026.

About the Age Calculator
An exact age is more informative than a rounded year count. It tells you how many days have passed since your last birthday, how long until the next one, and how many total days and weeks you have lived.
The calculator uses UTC calendar dates, so the result does not change with time of day. The share of an 80-year life is a rough reference point for thinking about time, not a prediction of how long you will live.
FAQ
Age Calculator — frequently asked
Why is the age in days a large number?
There are about 365.25 days in a year, so a 30-year-old has lived roughly 11,000 days. Counting days makes it easier to measure short intervals, such as the time until a contract ends.
What about leap years?
Leap days are included in the total days lived because they really passed. In non-leap years, a 29 February birthday is counted on 28 February in this calculator.
Is the 80-year figure a life expectancy?
No. It is a simple reference point used in time-awareness exercises. Life expectancy varies widely by country, sex, health and era, so use official statistics if you need a real figure.
Why do the numbers change each day?
The calculator uses today's date from your device. Days since your last birthday and until the next one update each day, while the birth date stays the same.
Is my birth date stored?
No. The date is used only in your browser and is not saved or sent.
