- Read the results.
Your age, down to the day
Put in a date of birth and you get the exact age in years, months and days. Plus a few fun numbers, like how many days, hours and minutes old that is.
It also shows the day of the week someone was born, their zodiac sign, and a countdown to the next birthday. You can set an "as of" date too, which helps for forms that ask your age on a specific date.
