when did greece change to the gregorian calendar
Adoption of the Gregorian calendar Other countries of eastern Europe, most notably Eastern Orthodox countries, adopted the Gregorian calendar in the 1910s or early 1920s. The last country of Eastern Orthodox Europe to adopt the Gregorian calendar for civil purposes was Greece, at the time under military administration following the 11 September 1922 Revolution, with Wednesday 15 February 1923 being followed by Thursday 1 March 1923.[13] The Soviet decree expressly limited the reform to lay (i.e. non-religious) matters, as did the Greek decree. None of these reforms affected the dates of religious holidays. (See below.)
Archaic Greece Archaic Greece was the period in Greek history lasting from the eighth century BC to the second Persian invasion of Greece in 480 BC,[1] following the Greek Dark Ages and succeeded by the Classical period. The period began with a massive increase in the Greek population[2] and a series of significant changes which rendered the Greek world at the end of the eighth century as entirely unrecognisable as compared to its beginning.[3] According to Anthony Snodgrass, the Archaic period in ancient Greece was bounded by two revolutions in the Greek world. It began with a "structural revolution" which "drew the political map of the Greek world" and established the poleis, the distinctively Greek city-states, and ended with the intellectual revolution of the Classical period.[4]
