When is the Mass for The Holy Innocents?

Please tell me when The Feast of the Holy Innocents.
I lost a baby and really want to know when the mass is that honors lost children.

December 28

The Latin Church instituted the feast of the Holy Innocents at a date now unknown, not before the end of the fourth and not later than the end of the fifth century. It is, with the feasts of St. Stephen and St. John, first found in the Leonine Sacramentary, dating from about 485. To the Philocalian Calendar of 354 it is unknown. The Latins keep it on 28 December, the Greeks on 29 December, the Syrians and Chaldeans on 27 December.

As mentioned in the previous posts the Feast of the Holy Innocents is Tuesday December 28. In NYC at the Church of the Holy Innocents all the unborn children are remembered at the Shrine of the Unborn. You may enter your child’s name to be entered in the Book which rests at the Shrine.
Holy Innocent Martyrs, pray for us and for the unborn
