Housecleaning: Wednesday of Holy Week has been a traditional day in many countries for housecleaning -- from the Jewish custom of cleaning before Passover.
=====================
Tenebrae (Latin for "shadows" or "darkness") is a Christian religious service celebrated in the Holy Week within Western Christianity, on the evening before or early morning of Maundy Thursday, Good Friday, and Holy Saturday. Tenebrae is distinctive for its gradual extinguishing of candles while a series of readings and psalms are chanted or recited.
These services traditional sing all of Jeremiah's Lamentations which have been set to music by a number of composers.
