The Eve of Nativity (December 24) is a strict fast day, called "Paramony" (lit. "preparation"), on which no solid food should be eaten until Sirius is seen in the evening sky (or at the very least, until after the Vesperal Divine Liturgy that day). If Paramony falls on a Saturday or Sunday, the day is not observed as a strict fast, but a meal with wine and oil is allowed after the Divine Liturgy, which would be celebrated in the morning.
