Find your exact age in years, months, days, and weeks. Discover fun stats like total days lived and days until your next birthday.
An Age Calculator is a simple tool that computes your exact age from your date of birth to today's date. Unlike a simple subtraction of years, a precise age calculator accounts for leap years, varying month lengths, and whether your birthday has occurred yet in the current year.
Our Age Calculator goes beyond just years — it tells you your age in years, months, and days with complete accuracy. It also provides additional statistics such as your total age in days, weeks, and total months, as well as the number of days remaining until your next birthday.
The calculation follows a precise three-step process:
For example, if you were born on March 15, 1990, and today is April 25, 2025: You are 35 years, 1 month, and 10 days old. Total days = 12,824.
Leap years occur every 4 years (with some exceptions for century years). A leap year has 366 days instead of 365. Our calculator automatically accounts for leap years when computing total days, ensuring maximum accuracy. If you were born on February 29 (a leap day), the calculator correctly handles the next birthday as either February 28 or March 1 depending on the year.
Our age calculator is highly accurate. It correctly handles leap years, varying month lengths (28, 29, 30, or 31 days), and precisely calculates years, months, and remaining days. The calculation is based on the current date at the time you run it in your browser.
This calculator computes age from your date of birth up to today's date. For calculating the age between two specific dates (not necessarily today), you would enter the earlier date as the "date of birth." The result will tell you the exact duration between the two dates.
If you were born on February 29, our calculator handles this edge case gracefully. In non-leap years, your birthday is effectively counted as March 1 for next birthday calculations. The total days and age calculation remain accurate regardless of birth date.
The calculator finds the date of your next birthday in the current year. If that date has already passed, it moves to next year. Then it counts the exact number of days between today and that upcoming birthday date.
Yes — the calculator uses your device's local date, which reflects your current time zone. If it's past midnight in your location, today's date is used. For maximum accuracy, ensure your device's date and time settings are correct.
