Frequently asked
How is the age worked out?+
Using real calendar lengths - actual month lengths and leap years - rather than assuming every month has thirty days. That is why the result can differ from a simple day-count divided by 365.
What else does it show?+
Totals in weeks, days and hours, the weekday you were born on, and how long is left until your next birthday.
Can I use it for something other than a birthday?+
Yes. It measures the gap between any two dates, so it works for anniversaries, notice periods, project durations or how old a document is.
