Questions
How is age calculated?
Full years first, then full months, then the remaining days, the same way you would count on a calendar. Someone born on 31 January turns one month older on the last day of February.
Does "days between" include both dates?
No, it counts the days from the first date up to the second, so Monday to Tuesday is 1 day. Tick "Include the end date" to count both.
What counts as a working day?
Monday to Friday. Public holidays differ by country, so they are not subtracted.
