Tenebrae (Latin for shaows) is a Christian religious service celebrated by the Western Church on the eves of Maundy Thursday, Good Friday, and Holy Saturday, which are the last three days of Holy Week. The liturgy of Tenebrae is characterized by the gradual extinguishing of candles while a series of readings and psalms are chanted or recited. Tenebrae is observed by the Roman Catholic Church (though not widely), and by some churches within the Anglican Communion. The name may also be used for various Holy Week services among Protestant churches.
