In the East Syriac tradition the liturgical year starts with Annunciation season.
But by the 20th century, due to influence of the Western tradition and the secular world, Christmas day (December 25) became the focal point of the season.
In the East Syriac Rite, the Season of Annunciation, like Advent in the Roman Rite, marks the start of the liturgical year, and begins on the Sunday that falls between November 27 and December 3 inclusive.
[1] The season extends past Advent to also include Christmastide.
[2][3] However, the present-day liturgical calendar of the Syro-Malabar Catholic Church (one of the churches that uses the East Syriac Rite) regards "Annunciation" and "Nativity" as separate seasons, with the Season of Annunciation ending prior to Christmas.
