This tuesday is the 29th of Touba which is the feast of the Annunciation, Nativity and Resurrection. It is also Jonah's fast. Lazarus Saturday is teh same day as the feast of the Annunciation this year.
Which rites would we follow in cases like these. What if the calendar shifted one day and Palm Sunday and the Annunciation where on the same day? They are two different feasts with different tunes and hymns yet they are equal in that they are both Major Feasts.
