For me it was the Apodosis of the Entry of the Theotokos into the Temple, but if I were on the Western Rite, it would have been the Feast of Christ the King.
Now, the Syriac Orthodox celebrated the Annunciation (they do this on the Sunday following the feasts of the Sanctification of the Church) - and this marked the start of Lent (the Roman Rite and its derivatives such as the Sarum Rite, Lutheran Rite and Anglican Rite are unique in having only four Sundays in Advent; all other liturgical rites have a longer Nativity Fast, usually six Sundays long, even the Ambrosian Rite of Milan, which is the ancient rite most closely related to that of Rome (it uses the Roman Canon rather than the highly variable Eucharistic Prayer of the Gallican and Mozarabic Rites, which changes so much that it might as well be multiple prayers). The Copts, who are on the Coptic Calendar, which is aligned with the Julian Calendar, were also one Sunday away from starting the Nativity Fast, and were celebrating the feast of St. Mina, the Holy Martyr and Wonderworker. The Eastern Orthodox on the Julian Calendar were celebrating the 24th Sunday after Pentecost and the feast of several Apostles of the Seventy, but basically, primarily it was Sunday according to tone seven in the Octoechos, more than anything, the closest thing to a Feria you’ll find in the Byzantine Rite. Definitely an occasion in the Slavonic churches for the use of the default gold vestments (which serve a role similar to green in the Western rites). Of course, this is purely a convention; it is not baked into the Typikon, which only specifies light or dark vestments. In the West Syriac Rite, I’m not sure what the Maronite practice is (although their vestments are beautiful, similiar to Eastern Orthodox vestments), but the Syriac Orthodox will often use multiple liturgical colors, and if two clergy are concelebrating, they will color-coordinate but not color-match, so one might be wearing a blue chasuable and the other a violet chasuble.*
* Technically, these are Phaynos; related to the Byzantine vestments; and some use Copes, sourced from Western vestment houses; the Church of the East also uses copes from Western vestment houses; conversely, if you’re able to track them down, the manufacturers of Syriac vestments in India produce the Phaynos for around $250, and the quality is exceptional - and business has not been good for many of them, for various reasons, so along with vestment makers in the Ukraine, its a good way to ethically source vestments by supporting a struggling community. For Anglican purposes, a Syriac Phayno would make an excellent Cope; also Syriac stoles would be usable, mainly by deacons over a plain white alb. The standard design features bunches of grapes in gold embroidery on a colored background.
). The congregation made the decision at the last minute to have communion, which I cannot celebrate for them. I had to consult with the lay worship leader and the person who was going to preside at communion to hand write a couple of adjustments to the bulletin they give me so we were all on the same page.
