It’s sometimes called Maundy Thursday,
also known as Sheer Thursday (as in to purge yourself of sin), Covenant Thursday, Great and Holy Thursday, and Thursday of Mysteries. Remember to wash your feet (or hands, for that matter,) or the feet of someone else, if you are so inclined.
Among the other things going on remember: don’t go to a dinner party with 12 other people –
This evening begins the Easter Triduum, (aka Holy Triduum, Paschal Triduum, or The Three Days,) the period of three days that begins with the liturgy on the evening of Holy Thursday and ends with Easter Vigil on Holy Saturday.
And so it goes
