Which Jewish Tradition Still Influences Christmas Celebrations and How Did the Custom Originate?

The celebration of Christmas begins with Midnight Mass, and the calendar date is December 25.

But every Christian knows that the reverence begins on Christmas Eve.

Christmas Eve comes directly from the Jewish custom of beginning religious rituals with ceremonies starting at sundown.

In other words, the evening before the holy day with candles and prayers lasting until the following sundown, in this case, Christmas Day.
