Frequently Asked Questions
How is exact age calculated?
By finding the difference between two dates in years, months, and days, accounting for varying month lengths and leap years.
Does this account for leap years?
Yes, the calculator accounts for leap years in all calculations.
Can I calculate age between any two dates?
Yes, change the 'As of Date' field to any date.
How are months with different lengths handled?
The calculator uses actual calendar months. If the end date's day is before the start date's day, it borrows from the previous month.
Why might my age calculation differ from other tools?
Different tools may handle edge cases (like Feb 29 birthdays) differently. This calculator uses standard calendar arithmetic.
