How is the date of Easter determined?

Why is Easter date determined this way?

• ''The first Sunday after the full moon after the Spring equinox.'' April 5th this year. I just looked into it and that's what it is this year. Why exactly is it determined this way?

• Answer:

  The approximate dates for Easter are outlined in the Bible, and was originally celebrated around the time of the Jewish passover, as that is when the Crucifixion is said to have taken place. In 325 the Council of Nicea decided on a more precise method of calculation, which combined the two methods that were in practice at that time - calculating it based on moon phases and having a specific set date. From that point forward, the date of Easter would be on a day following the first full moon, after the Spring Equinox, though it took quite a bit longer for Sunday to become the generally accepted day across all communities. It is important to note, that though there have been references made to Easter being associated with the Goddess Eostre (primarily due to Bede), it is likely this may have been an error on his part (or at least had no basis in provable fact). Details are rather sketchy on her existence and it is possible that she was simply associated with the dawn, and new beginnings, rather than Spring itself. Also, historically "Eostre-month" was a month long celebration, rather than any one particular day. * http://theinformedpagan.org/2012/04/03/the-origins-of-easter/ *
