Each Western and Orthodox church has a period of preparation prior to Christmas, known as Advent or Nativity Fast, with liturgical colours of violet-purple-blue and redgold.
Many Christians in each church attend a service the evening prior to Christmas, known as Christmas Eve or Eve of the Nativity, which can include an all-night vigil.
Differences between Western and Eastern churches include a greater focus on fasting prior to Christmas in the Eastern Churches, particularly on the Eve of the Nativity.
Western churches have distinct traditions during Advent, including Advent calendars, Advent wreaths, carol services, nativity plays and a Christingle service.
Western churches celebrate Christmas on 25 December (Gregorian calendar), while Orthodox churches celebrate on 07 January following the Julian calendar.
Holy week is celebrated beginning the sixth Sunday of Lent, remembering Jesus’ celebratory entry into Jerusalem when palm branches were laid down on the path before him by his followers.
Holy Week includes remembering the last supper on Thursday (Maundy Thursday/Holy and Great Thursday), remembering the events of Jesus’ torture and crucifixion (Good Friday/Holy and Great Friday) and culminating in a joyful celebration of the resurrection on Easter Sunday morning.
Differences between Western and Eastern churches include Lent beginning on Ash Wednesday in the West (ashes made from previous years’ palms placed on foreheads) and Clean Monday in the East (spiritual cleansing; fasting).
During Lent, Laetare (rejoicing) and Mothering Sundays are celebrated in Western churches, while Orthodox churches have a commemoration of St Gregory Palamas and Mary.
