Lifetime Calculator
Our Lifetime Calculator helps you calculate exactly how long you’ve been alive — in years, months, weeks, days, hours, minutes, and even seconds.

What Is a Lifetime Calculator?
A lifetime calculator (also called an age calculator) measures the total time between your date of birth and today’s date.
Unlike simple age tools that only show years, this calculator provides a complete time breakdown including:

- ✅ Total Weeks
- ✅ Total Days
- ✅ Total Hours
- ✅ Total Minutes
- ✅ Total Seconds
It updates based on the exact current date and time.

How the Lifetime Calculator Works
The calculator:
- Takes your selected birthdate
- Compares it with the current date and time
- Calculates the total time difference
- Converts that difference into multiple units
Time Conversions Used:
- 1 minute = 60 seconds
- 1 hour = 60 minutes
- 1 day = 24 hours
- 1 week = 7 days
- Months calculated based on calendar difference
- Years adjusted for month/day differences
If a future birthdate is entered, the tool will display an error.
Example Calculation
If someone was born on:

- Weeks: Total weeks lived
- Days: Total days alive
- Hours: Total hours lived
