Today is the feast of the Dominican Saint Hyacinth...

Although until Pius X it was celebrated yesterday (Introibo, CE, Wiki). The Dominicans' proper version of the Pauline Kalendar appears to retain the feast but it isn't kept in the general one so far as I can tell. 

It is also the feast of Saint Clara of the Cross (13th century), of Saint Elias (10th century), and of Saint Carloman (8th century).

V. Et álibi aliórum plurimórum sanctórum Mártyrum et Confessórum, atque sanctárum Vírginum. R. Deo grátias.
