The Christmas or Yule (Jól in Icelandic) celebration in Iceland starts four Sundays before Christmas proper, which begins on December 24 (Advent) and ends thirteen days later on January 6. Traditionally, one candle is lit each Sunday until four candles are lit on the 24th. At 6:00 pm Church bells ring to start the Christmas celebration. The religiously observant and/or traditional Icelanders will attend mass at this time while the secular Icelanders will begin their holiday meal immediately. After the meal is finished, they open gifts and spend the evening together. In Iceland people over the Yule holidays most often eat smoked lamb, ptarmigan and turkey. Pork is also very popular.
