About this tool
This page opens the age calculator with the millennium year 2000 already entered — set your day and month of birth to get your exact age instantly. People born in 2000 turn 26 on their birthday in 2026; before it they are still 25. In 2027 they turn 27.
Being born in 2000 makes the math feel easy — your age always matches the calendar year's last two digits after your birthday — but the exact count still depends on the day. 2000 was also a rare leap year (divisible by 400), so February 29 babies from that year have a real birthday only every four years; this calculator handles that correctly.
Fill in the day and month above for your age in years, months and days, the total days you have lived (around 9,500 by your mid-twenties), and a countdown to your next birthday. Your data never leaves the browser.
Example. A birth date of 1 January 2000 read on 21 September 2026 is 26 years, 8 months and 20 days, with 102 days left until turning 27.
Limit. The year must be from 1000 through the current year, and a 29 February birthday is placed on 28 February in a non-leap year.
