About the Age Calculator
This Age Calculator computes a person's age from their date of birth using client-side logic so no personal data is transmitted. It also supports calculating durations between two dates for planning, record-keeping, and timelines.
Features
- Calculate exact age in years, months and days from a birthdate.
- Compute the difference between two dates to find durations (e.g., project timelines).
- Handles leap years and varying month lengths for accurate results.
Common use-cases
- Determining age for forms, registrations and eligibility checks.
- Calculating durations between events for planning and reporting.
- Quickly checking ages for milestone planning (birthdays, anniversaries).
Tip: The calculator runs entirely in your browser and does not upload dates anywhere — use it confidently for private, local calculations.
