  1. You must have JavaScript enabled in your browser for this calculator to work. Requires Netscape 3.0 or Internet Explorer 3.0 or later for correct operation.
  2. All fields are editable. Change Gregorian date to calculate Julian Day Number and day-of-week, or vice versa.
  3. After changing a text box, click outside of the calculator, or press tab, to update all other data. (Don't press return.)
  4. In Auto mode, Gregorian calendar changes from Julian to Gregorian between October 4/15, 1582. For dates after that date, as in England and colonies until 1753, select Julian Only.
