How Age is Calculated

Traditional age calculation follows three rules:

Subtract birth year from current year
If birthday hasn’t occurred yet this year, subtract 1
Calculate months/days since last birthday

Our Age Calculator enhances this with:
✔ Automatic leap year adjustment
✔ Precise month length calculations
✔ Time zone compensation
✔ Daylight saving awareness

Example Calculation:
Birthdate: July 20, 1985
Today: October 25, 2023
Age = 38 years, 3 months, 5 days

How Many Days Until...?

Days until your next birthday
Time remaining until retirement
Duration until special anniversaries
Countdown to vacations or events
Try it: “How many days until I turn 40?” Enter your birthdate and compare date as your 40th birthday in our Calculator for an exact countdown.

An Age Calculator helps you determine your precise age in years, months, and days by entering your birth date. This tool provides instant results, whether for legal documents, health tracking, or fun. Simply input your date of birth and the current date, and get your age in seconds!
