Gregorian Calendar:The Gregorian calendar is a blessing in human’s life. Invented in 1582, the system adopted a leap year cycle different than the one employed by the Julian calendar. The new calendar was considered an improvement on the earlier Julian model. In the Gregorian calendar, four years make up a cycle, with an extra or “leap” day added to the fourth year to keep the dates and months synchronized with the solar cycle.
