Frequently asked questions
Does it account for leap years?
Yes. The calculation uses real calendar dates, so leap years and varying month lengths are handled correctly.
Can I calculate age on a future or past date?
Yes. Set the "age at" date to any date — future or past — to find how old someone is or was on that specific day.
How is the time until the next birthday counted?
The tool finds the next upcoming birthday from the target date and shows the exact number of days remaining, accounting for leap years.
