Radunitsa Radunitsa - the Second Tuesday after Easter, alternately May 1 This was originally called Nav Dien (Day of the Dead). Feasts are held in the cemeteries. Offerings of eggs, beer, vodka and other food are left for the dead. The name of the festival may derive from the god Rod. The majority of scientists agree that the origin of word “Radunitsa” is “rada” (“glad”) or “radzittsa” (“to be glad”). Belarusians ask their ancestors to help them get a good harvest on this day. In spite of the holiday’s close connection with Christianity, it has a pagan origin http://www.belradio.fm/en/468/reports/17243/ Day of the Holy Spirit Pentecost Kataklysmos Tuesday of St. Thomas Week (the second week after Easter), originally a pagan holiday celebrating ancestors (9) http://clover.slavic.pitt.edu/~tales/saints.html
the 9th day after Easter, is the holy day of Radunitsa, when the Orthodox Christians traditionally visit the graves of their relatives and hold requiem services.
      By commemorating the deceased the Orthodox convey their faith in eternity of the soul and universal resurrection.
      As a matter of fact the custom dates back long before Russia`s conversion into Christianity. Radunitsa is initially a pagan holiday of the Eastern Slavs. The name is akin to the word `radost`, i.e. `joy`. After the Christening the Slavs started celebrating it on the first Sunday after the Easter, or on the following Monday or Tuesday.
      There is an old custom to bring food (mainly pancakes as the sun symbol) and wine to the graves, lament over the graves, sing, and dance and play on this day.
