How Old Am I?
What the age calculator shows
Enter a birth date to see the exact age in years, months and days as of today, Sunday, October 4, 2026, along with the total days, weeks and months lived, the weekday of birth and the date of the next birthday.
How age is counted
Age is counted in completed years: you turn a year older on the anniversary of your birth date. The calculator then counts the completed months since the last birthday and the days since the last monthly anniversary.
Born in a certain year
If you only know a birth year, the pages for each year show an approximate age and explain that the exact age depends on whether the birthday has passed yet this year.
