Age Calculator FAQs
How is age calculated?
Age is calculated by counting the number of full years, months, and days between the birth date and the selected date. The calculation accounts for leap years and varying month lengths.
Why do months have different numbers of days?
Our calendar months have varying lengths (28-31 days) due to historical reasons. The age calculator accurately handles these differences in its calculations.
What about leap years?
The calculator automatically accounts for leap years (years divisible by 4, except century years not divisible by 400) in all calculations.
Can I calculate age at a future date?
Yes! Simply enter a future date in the "Age at Specific Date" field to calculate how old you will be on that date.
How accurate is the calculator?
The calculator is highly accurate and accounts for all calendar variations including leap years and different month lengths. It provides exact age down to the second.
