An Advent candle is a candle marked with the days of December up to Christmas Eve. It is typically used in a household rather than a church setting: each day in December the candle is burnt down a little more, to the mark for the day, to show the passing of the days leading up to Christmas. As with reusable Advent calendars, some Advent candles start marking the days from 1 December, rather than the exact beginning of Advent. Some households will make a Christmas decoration out of sprigs of evergreen and Christmas ornaments, with the candle at its centre; others will simply put it in a candlestick. It is usually burned at the family evening meal each day.

Blue Christmas in the Western Christian tradition, is a day in the Advent season marking the longest night of the year. On this day, some churches in Western Christian denominations hold a church service that honours people that have lost loved ones and are experiencing grief. These include parishes of Catholicism, Lutheranism, Methodism, Moravianism, and Reformed Christianity. The Holy Eucharist is traditionally a part of the service of worship on this day. This worship service is traditionally held on or around the longest night of the year, which falls on or about December 21, the Winter Solstice. There is an interesting convergence for this day as it is also the traditional feast day for Saint Thomas the Apostle. This linkage invites making some connections between Saint Thomas's struggle to believe in Jesus' resurrection, the long nights just before Christmas, and the struggle with darkness and grief faced by those living with loss.
