Enter a date of birth and get an exact age — years, months and days, not just a rounded year. Also shows total days, the weekday of birth, and how far away the next birthday is.
How is age in months and days worked out? Count whole years first, then whole months from the last birthday, then the remaining days. Borrowing across months with different lengths (28 to 31 days) is where hand calculations usually go wrong — this calculator handles the calendar exactly.
What day of the week was I born on? Enter your date of birth above and it is shown with your results, along with the date of your next birthday and how many days away it is.
