holy thursday, Batman!
"Maundy Thursday is the Christian holy day falling on the Thursday before Easter. It commemorates the foot washing and Last Supper of Jesus Christ with the Apostles, as described in the canonical gospels. It is the fifth day of Holy Week, preceded by Holy Wednesday and followed by Good Friday. The name comes from the Latin word mandatum, "commandment", which comes from Jesus' words "I give you a new commandment"."
