How to Calculate Age Accurately
Calculating age correctly is important for legal documents, healthcare, job applications, and educational records. Age is typically calculated as the number of full years between a person’s date of birth and the current date.
The basic formula is:
Age = Current Year − Birth Year
However, this only gives a rough estimate. For an accurate result, you must check whether the birthday has already occurred in the current year.
📆 Accurate Method
Compare the full birth date (day, month, year) with the current date:
- If the birthday has passed this year → subtract years directly.
- If not yet passed → subtract one more year.
📱 Use a Tool for Precision
Calculating manually can be error-prone, especially for leap years or edge cases like February 29. Our Age Calculator gives exact results including:
