Most people come to Greece in the summer, especially August, when Greece is crowded and less personal, and the penetrating sun bleaches hot afternoons. Walkers, nature lovers, and devotees of classical and Byzantine Greece would do better to come in the spring and fall, both being cooler and less tourist-riddled.
Spring's islands burst with thousands of varieties of wildflowers, and sprightly crimson poppies dapple stern marble blocks, but the sea is cold. Autumn days are short. This is when zesty olives are gathered, bulging grapes are pressed, and verdant fields plowed.
New Year's Day, Epiphany (January 6), Clean Monday, first day of Lent, Feast of the Annunciation and Independence Day (March 25); Easter holidays (in May); Labor Day (May 1); Pentecost, Assumption of the Holy Virgin (August 15); Ochi Day (October 28); Christmas Day, Boxing Day (December 26).
Only on Orthodox Easter and August 15 do you find most establishments closed.
Rooms are hard to get around Easter and August 15 (especially the latter). Traveling around this time, however, offers a compelling glimpse into Greek culture.
The Euro is the official currency. Airports, banks, hotels, and rail stations can exchange currencies. Many local restaurants do not accept credit or debit cards so make sure to have some cash on hand when out and about.
