Simple Age Calculator is a free, browser-based tool for finding chronological age from a date of birth and a chosen date. It provides a clear answer without an account, download or complicated setup.
What you can calculate
- Exact age in completed years, months and days
- Age on a past or future date, including an official cutoff date
- Total days and weeks lived
- Time remaining until the next birthday
How it works
Enter a birth date and choose today or another date. The result is calculated in your browser and accounts for calendar month lengths and leap years.
