I would suspect that this happens with St. Sharbel's feast day too. (That's the way they spell it in Portland.)
No. Today is his feast and we celebrated a special liturgy developed around the life of this saint. The Sedro and Mazmooro prayers, as well as the opening and closing hymns, introduce the Christ like qualities of St. Charbel. Quite beautiful!
On Wednesday, we will complete our novena and celebrate another beautiful liturgy developed around St. Ann. Our church has been full of Roman Catholics each night throughout the novena. They love this saint and especially our Novena in her honor.
The only other special liturgy we celebrate is in honor of St. Maron, for whom our Church is named. His feast day is on February 9 and it is a Feast Day of Obligation.
As for the spelling - Charbel vs Sharbel - both are correct. They are transliterations of the Arabic. We see these different spellings quite often with the Maronite hymns that have been written using the Latin alphabet.
If I'm not mistaken, Saint Charbel (Sharbel) appears on the Latin calendar of saints, sometime in December. We follow the Maronite calendar.
