How the answers are worked out
Every calculator here works on whole calendar dates, read from your own device, so the answers match the calendar on your wall rather than a server’s time zone. Months are counted as calendar months, leap years are handled by the calendar itself, and each page shows the rule it used, with a worked example. Holiday dates come from the published rules of each country. Read more about our method.
