QUESTIONS
Frequently asked questions
How is age worked out?
First full years, then full months, then the days left over, just as you would count on a calendar. Someone born on January 31 becomes a month older on the last day of February.
Does "days between dates" count both dates?
No. It counts the days from the first date to the second, so Monday to Tuesday is 1 day. Check "Include the end date" to count both.
What counts as a working day?
Monday through Friday. Public holidays vary from country to country, so they are not taken out.
