Advent
Advent, (from Latin adventus, “coming”), in the Christian church calendar, the period of preparation for the celebration of the birth of Jesus Christ at Christmas and also of preparation for the Second Coming of Christ. In Western churches, Advent begins on the Sunday nearest to November 30 (St. Andrew’s Day) and is the beginning of the liturgical year. In many Eastern churches, the Nativity Fast is a similar period of penance and preparation that occurs during the 40 days before Christmas. The date when the season was first observed is uncertain. Bishop Perpetuus of Tours (461–490) established a fast before Christmas that began on November 11 (St. Martin’s Day), and the Council of Tours (567) mentioned an Advent season.
The liturgical meaning of the Advent season referred to the dual “coming” of Jesus. In Roman Catholicism the traditional liturgical color for Advent is violet; many Protestant denominations have adopted blue or purple. The third Sunday of Advent, known as Gaudete Sunday, is commonly marked by the use of rose-colored vestments and candles.
Many churches and Christian homes mark the four Sundays of the season with an Advent wreath, which consists of four candles—typically three violet and one rose-colored—surrounded by greenery or other decorations. The first candle is lit the first Sunday of Advent, often with a prayer or devotion, and the following week the first and second candles are lit, and so on. The tradition, which began in the 19th century but had roots in the 16th, originally involved a fir wreath with 24 candles (the 24 days before Christmas, starting December 1), but the awkwardness of having so many candles on the wreath reduced the number to four. The candles are often said to symbolize hope, peace, joy, and love, respectively.
An analogous, and often secular, custom is the Advent calendar, which provides 24 openings, one to be opened each day beginning December 1. According to tradition, the calendar was created in the 19th century by a Munich housewife who tired of having to answer endlessly when Christmas would come. The first commercial calendars were printed in Germany in 1851, and often reveal a chocolate or other treat behind each door.
