If you want to calculate your exact age or determine the time difference between two dates—whether from the past or future—this calculator is perfect for you. It provides results in years, months, weeks, days, minutes, hours, and even seconds.
Whether you’re using it for fun or practical purposes, it’s a quick and handy tool for getting precise time calculations.
Age And Date Difference Calculator
How This Calculator Works
This is a simple date difference calculator. Since age is essentially the difference between two dates, we combined both functions into a single universal tool. Whether you want to calculate your age or the time gap between two dates, this calculator does it all.
Getting Started
The calculator has two main inputs:
- Start Date
- End Date
If you’re calculating your age, the Start Date should be your birthdate. For the End Date, you can select today’s date (there’s even a shortcut to choose it automatically).
How to Use
You have two ways to enter dates:

- Type the date manually in MM/DD/YYYY format.
- Click the calendar icon to pick a date from the calendar.
Repeat the process for the End Date.
This is helpful not just for age calculation, but also for practical needs. For example, job applications sometimes ask, “How old are you as of the application deadline?” If the last date is May 31st, simply enter that as the end date, and you’ll get your exact age.
Multiple Time Formats
The calculator gives you results in various formats for convenience:
Example: From 01/13/2025
to 04/30/2025
- → 0 year(s), 3 month(s), and 17 day(s)
- → Or 3 month(s) 17 day(s)
- → Or 15 week(s) 2 day(s)
- → Or 107 day(s)
- → Or 2,568 hour(s)
- → Or 154,080 minute(s)
- → Or 9,244,800 second(s)
Whether for fun or practical use, this tool helps you quickly find precise time differences in multiple formats.
