Gregorian Calender

The time calculation which is used by western cultures and accepted worldwide today is the 365-days calendar known as the Gregorian calendar. It expresses its own incorrectness by adding one day every four years in February, the so called leap year, in order to correct and re-adjust the deviations that develop in that time period. Nowadays mankind uses the calendar no longer as a fundamental basis for mediating time qualities, but considerably for counting and dividing.
