Advent is a penitential season that starts four weeks before Christmas in Catholic and Orthodox-christian churches. As in lent (before Easter) we pray, fast and give alms to prepare our hearts for the "coming" (advent) of Christ (from the Latin "adveniat regnum"--coming of Christ's kingdom.) The first Sunday of Advent in 2013 is December 1. Here are free printable advent calendars (secular and religious) Free Printable Advent Calendar Crafts for Kids
