> A visit to Mount Athos also involves literal time travel. The monasteries there still go by Byzantine time, in which the day begins at sunset, not midnight, so the time zone changes literally every day. Visitors may have to set their watches back by as much as seven hours as they cross the border. And don't forget to change the date as well. Mount Athos never adopted the new-fangled 16th-century Gregorian calendar; they still use the Julian calendar of the Roman Empire, which lags 13 days behind. It's almost two weeks ago there!
