Age Calculator

Our age calculator tells you your exact age in years, months, and days based on your date of birth and today's date. It also shows how many days remain until your next birthday. Age calculations are more complex than they appear — months have different lengths, and leap years add an extra day every four years. Our calculator handles all of these edge cases correctly, giving you a precise result regardless of when you were born. You can also calculate the age or duration between any two dates — useful for working out how long you have been in a job, how old a child will be on a specific date, or how many days until an important event.
