calendar dates. Simply enter the start and end date to
calculate the duration of any event. You can also use this

Britain and the eastern part of what is now the United States.
For best results, use dates after 1752 or verify any data

have many variations, including the ancient Roman calendar
and the Julian calendar.
Leap years
are used to match the calendar year with the astronomical year.
