Calendar, so called from the Roman Kalends, is a method of distributing time into certain periods adapted to the purposes of civil life, as hours, days, weeks, months, years etc. The development of calendars marks an important contribution to the organization of knowledge because they make it possible to organize phenomena in time in an univocal way.



The Gregorian calendar (1582) is the de facto international standard, and is used almost everywhere in the world for civil purposes.
