The greatest holiday of the year is New Year's, which is literally celebrated all night. First you eat a big dinner before midnight and then another after midnight. In this manner you eat "to the old year" and then "to the new year." New Year's is celebrated in family apartments, but people also go out for walks late in the night.
Christmas is also celebrated, not on December 25th but on January 7th, the Orthodox Christmas. Some other holidays include International Women's Day (March 8), in which all women are given gifts and they do not have to work at all. For the most part, those three are the biggest holidays. Of course there are others -- like Men's Day, Workers' Day, and Remembrance Day.
