Age calculator – how many years, months and days you count

Knowing your exact age is not always as obvious as it sounds: the years are counted easily, but exactly how many months and days have passed since you were born? Our age calculator works it out in an instant. You simply enter your date of birth to get your age in years, months and days, plus the total number of days you have lived. It is an accurate, free service without registration, made for every visitor.

When is calculating your age useful?

Knowing the exact age is practical in many situations, and not only out of curiosity:

  • filling in forms and documents that require an exact age;
  • knowing how many days or months old a baby is;
  • checking whether the minimum age for an action or activity has been reached;
  • preparing a birthday or a special anniversary;
  • calculating the age difference between two people;
  • keeping track of personal milestones, such as the number of days lived.

The calculator takes leap years and months of different lengths into account, so the result is always accurate, no matter how distant the date of birth is.

How do you use the age calculator?

Operation is very simple, both with the mouse and by entering the date:

  1. Enter your date of birth in the relevant field – manually or via the calendar.
  2. Click the «Calculate!» button.
  3. You see the age in years, months and days, plus the total number of days you have lived.
  4. You can change the date and recalculate as many times as you like.

Use is fast and free, without installation and with online access. If you want to know which day of the week you were born on, use the day of the week calculator; and to count the days between two dates, the number of days between dates.
