Frequently Asked Questions
How does the age calculator handle leap years?
Our age calculator automatically accounts for leap years when calculating your exact age. February 29th birthdays are handled correctly for both leap and non-leap years.
Can I calculate my age on a future date?
Yes! Simply change the 'Today's Date' field to any future date to see what your age will be on that specific day.
Why is my age in months/days showing differently than expected?
Our calculator uses chronological calculation - if you're 5 days into a new month since your birthday, it shows those 5 days. Months with different lengths (28-31 days) are handled precisely.
Can I use this for official age verification?
While our calculator is accurate, official age verification should use government-issued documents. This tool is great for quick reference and personal use.
