Feast of St. Basil (Ayios Vassilios). St. Basil is the Greek equivalent of Santa Claus. The holiday is marked by the exchange of gifts and a special cake, vassilopita, made with a coin in it; the person who gets the piece with the coin will have good luck. January 1.
Epiphany (Baptism of Christ). Baptismal fonts and water are blessed. A priest may throw a cross into the harbor and young men will try to recover it; the finder wins a special blessing. Children, who have been kept good during Christmas with threats of the kalikantzari (goblins), are allowed on the 12th day to help chase them away. January 6.
Carnival (Karnavali). Be ready for parades, marching bands, costumes, drinking, dancing, and general loosening of inhibitions, depending on the locale. Some scholars say the name comes from the Latin for "farewell meat," while others hold that it comes from "car naval," the chariots celebrating the ancient sea god Poseidon (Saturn, to the Romans). The city of Patras shows its support of the latter theory with its famous chariot parade and wild Saturnalia, private parties, and public celebrations. Masked revels are widely held in Macedonia. On the island of Skyros, the pagan "goat dance" is performed, reminding us of the primitive Dionysiac nature of the festivities. Crete has its own colorful versions, whereas in the Ionian Islands, festivities are more Italian. In Athens, people bop each other on their heads with plastic hammers. Celebrations last the 3 weeks before the beginning of Lent.
Independence Day and the Feast of the Annunciation. The two holidays are celebrated simultaneously with military parades, especially in Athens. The religious celebration is particularly important on the islands of Tinos and Hydra and in churches or monasteries named Evangelismos (Bringer of Good News) or Evangelistria (the feminine form of the name). March 25.
Sound-and-Light Performances. These begin on the Acropolis in Athens and in the Old Town on Rhodes. Nightly through October.
Feast of St. George (Ayios Yioryios). The feast day of the patron saint of shepherds is an important rural celebration with dancing and feasting. Arachova, near Delphi, is famous for its festivities. The island of Skyros also gives its patron saint a big party on April 23. (If the 23rd comes before Easter, the celebration is postponed until the Mon after Easter.)
Holy Week Celebrations -- Orthodox Easter, a time of extraordinary festivities in Greece, usually falls one or more weeks after Easter in the West; inquire ahead! The Good Friday exodus from Athens is amazing, and you can remain and enjoy the deserted city or, if you're fortunate and have made reservations, because Greeks take up most of the travel facilities, you can be among the celebrants in any town or village. Holy Week is usually marked by solemn services and processions, and serious feasting on roasted lamb, the traditional margaritsa soup, and homemade wine. Dancing takes place, often in traditional costumes. In a unique celebration on Patmos, the Last Supper is reenacted at the Monastery of St. John the Divine. Tip: Tourists must dress appropriately during this special time. Shorts, miniskirts, and sleeveless shirts will not only offend Greeks, but will prohibit your entry to religious sites.
May Day. On this urban holiday, families have picnics in the country and pick wildflowers, which are woven into wreaths and hung from balconies and over doorways. May Day is still celebrated by Greek communists and socialists as a working-class holiday. May 1.
Hippocratic Oath. Ritual recitations of the oath by the citizens of Kos honor their favorite son, Hippocrates. Young girls in ancient dress, playing flutes, accompany a young boy in procession until he stops and recites in Greek the timeless oath of physicians everywhere. May through September.
Feast of St. Constantine (Ayios Konstandinos). The first Orthodox emperor, Constantine, and his mother, St. Helen (Ayia Eleni), are honored, most interestingly, by fire-walking rituals (anastenaria) in four villages in Macedonian Greece: Ayia Eleni, Ayios Petros, Langada, and Meliki. It's a big party night for everyone named Costa and Eleni. (Name days, rather than birthdays, are celebrated in Greece.) The anniversary of the Ionian reunion with Greece is also celebrated, mainly in Corfu. May 21.
