When does Easter start?

Easter is old. The name was brought to Britain by the Anglo-Saxon settlers, but its celebration of the Vernal Equinox is an essential part of the earliest calendar-worship, dating from the Stone Age at least. The Christian Paschal feast that became attached to Easter, and is called "Passover" in most languages ( Pâques or Pascuas or Πασχα, from a form of the Aramaic pascha), is relatively recent, dating from the 1st Century AD, but it derives of course from the time of the Israelites' Exodus from Egypt.
