Reformed, or Corrected, KALENDAR, is that which, setting aside all apparatus of golden numbers, epacts, and dominical letters, determines the equinox, with the paschal full-moon, and the moveable feasts depending thereon, by astronomical computation, according to the Rudolphine Tables.
This kalendar was introduced among the Protestant states of Germany in the year 1700, when 11 days were at once thrown out of the month of February; so that in 1700, February had but 18 days: by this means, the corrected style agrees with the Gregorian. This alteration in the form of the year, they admitted for a time; in expectation that, the real quantity of the tropical year being at length more accurately determined by observation, the Romanists would agree with them on some more convenient intercalation.
