Frequently Asked Questions About Chronological Age & Birthdays

The calculator computes exact chronological age by comparing the start date (Date of Birth) with the target date (or real-time clock). It accurately accounts for varying month lengths (28, 29, 30, or 31 days) and leap years, borrowing days from the previous month where necessary to display standard legal years, months, and days.
