Age Calculator: Exact Age in Years, Months and Days

What is it?

The Age Calculator tells you your exact age in years, months and days. It also shows your age in total months, weeks and days, the weekday you were born, and how many days are left to your next birthday.

Who is it for?

Students and job seekers checking age limits for exams and recruitments, parents for school admissions, and anyone filling forms that ask for exact age.

How to use it

Enter the Date of birth. Age on this date is today by default; change it to check age on a past or future date. The answer appears as you type; there is no Calculate button. Tap Copy result to copy it, or Share on WhatsApp to send it.

Age on a cut-off date

Exams and job forms (UPSC, SSC, state recruitments, school admissions) set age limits “as on” a date, such as 1 August. Enter that date in Age on this date. Read the notice carefully: some count age as completed years only, and age relaxations for categories are added separately.

How months are counted

  • Months are counted calendar month to calendar month, so 31 January to 28 February is 0 months 28 days.
  • People born on 29 February have a birthday on 1 March in non-leap years in this calculator; some countries legally use 28 February.

Good to know

Use the date on your birth certificate or Class 10 certificate, which most offices treat as your official date of birth.

Errors and how to fix them

  • “The second date must be after the date of birth”: check the year in Age on this date.
  • “Choose a date”: a date box is empty.
