Since ancient times, calendars have been a vital part of civilization. Calendars divided time over extended periods and arranged them in a definite order, making them convenient for regulating daily life, religious holidays, and for historical and scientific purposes (“Calendar”). Throughout history, however, people aimed to improve previous calendar systems, and many times, these reasons were political. Politics affected both the motivation for calendar reform and the implementation of these new systems. Authority figures were primarily responsible for edits to the calendar. When the calendar fell out of sync with natural events like solstices and equinoxes, reform was the answer. The solution the Romans had was to have an extra …show more content…

An example can be seen in the Gregorian reform in Europe. In Christian Europe, the greatest concern surrounding the calendar was to properly identify feast days, especially Easter (Feffer). In the early centuries of Christianity, different sects chose to celebrate Easter on different days, based in part on conflicting testimony from the four Gospel texts. Justifying the selection of a particular date for Easter was thus of great importance in helping to support the ultimate authority of each church (Feffer). When it became clear to religious figures that their calendar calculations were inaccurate and the equinox was clearly falling some days earlier, it was feared that Easter was being celebrated on the "wrong" date, and thus calendar reform was needed (Dowd). While concern for astronomical accuracy might have been significant to some, the overwhelming concern for those who proposed reforming the calendar was a religious one and ensuring that Easter, the most important religious festival of the year was celebrated at the proper time. Indeed, the place of Easter in the calendar determined the position of the rest of the church’s movable feast days (“Calendar”). When religious authorities felt like they were inaccurate, they dedicated themselves to resolving this conflict …show more content…

However, since authorities were the ones creating change to the calendar, others’ acceptance of these changes was charged with implications. The most significant example of this backlash can be seen with the Gregorian reform, which was initiated by the pope via a papal bull. This was an issue for Protestants, as accepting the papal bull would appear to be recognizing the authority of the Catholic church, and even Roman Catholic countries took care to adopt the new calendar via their own civil acts (Poole). The key issue was not the content of the new calendar but the people related to the new calendar; Protestants had little scientific objections and also wanted to effectively establish the date of Easter (Dowd). The defiance of the pope was clearly of importance to Protestants, however, as they attempted to skirt around the issue. In Germany, scientists advocated for a reform based on the proposal that made the same changes as the Gregorian reform but used the scientist Kepler's Rudolphine Tables, rather than the epacts, to calculate Easter, avoiding using a Roman Catholic method, and thereby denying the authority of the Pope (Dowd). Even in the regions of Bohemia and Augsburg there were even
