“The exact origins of this religious feast day’s name are unknown. Some sources claim the word Easter is derived from Eostre, a Teutonic goddess of spring and fertility. Other accounts trace Easter to the Latin term hebdomada alba, or white week, an ancient reference to Easter week and the white clothing donned by people who were baptized during that time. Through a translation error, the term later appeared as esostarum in Old High German, which eventually became Easter in English. In Spanish, Easter is known as Pascua; in French, Paques. These words are derived from the Greek and Latin Pascha or Pasch, for Passover. Jesus’ crucifixion and resurrection occurred after he went to Jerusalem to celebrate Passover (or Pesach in Hebrew), the Jewish festival commemorating the ancient Israelites’ exodus from slavery in Egypt. Pascha eventually came to mean Easter.
Easter is really an entire season of the Christian church year, as opposed to a single-day observance."
The article goes on to explain that the Easter season begins with Lent 40 days before Easter and going 50 days after to celebrate the Ascension and Pentecost.
