Easter did not cleanly replace one single holiday. Historically, it is a Christian holiday centered on Jesus’ resurrection , while some later traditions and folklore connected it to older spring/fertility customs and the Anglo-Saxon spring goddess Eostre.

Quick answer

If you mean the common claim online, people usually say Easter “replaced” a pagan spring festival associated with Eostre , but that idea is debated and not universally accepted by historians.

What’s more certain

  • Easter’s Christian observance is tied to Passover and the resurrection of Jesus , not to a single pagan holiday.
  • The timing of Easter was standardized in early Christianity, with the date set around the first Sunday after the first full moon on or after the spring equinox.
  • Some modern Easter symbols, like eggs and bunnies, are often explained through broader spring symbolism , not as proof that Easter directly replaced one specific ancient holiday.

Bottom line

So the safest answer is: Easter is a Christian holiday, and the idea that it replaced a pagan festival of Eostre is a later theory, not a settled fact.
