Calculate exact age in years, months, and days
What is Age Calculator?
The Age Calculator determines an individual's exact age in years, months, and days based on their Date of Birth (DOB). Unlike simple subtraction of years which can be off by one, this tool accounts for leap years and months with 30/31 days.
📊 Practical Example
"If born on 15 Aug 1999 and checking age on 1 Jan 2025: Manual math is hard because of month differences. The calculator instantly tells you: 25 Years, 4 Months, 17 Days."
⚠️ Common Mistake
Only subtracting the year (e.g., 2025 - 2000 = 25). This is wrong if your birthday hasn't passed yet in the current year. Always calculate age down to the exact day.

Additional Information
Why is it hard to calculate age manually?
Calculating age seems simple (Current Year - Birth Year), but it gets tricky when you need the exact months and days. For example, if today is 15th Jan and you were born on 20th Feb, simply subtracting years gives the wrong 'completed' age.
