Easter is named after the goddess of fertility, Oestre, whose festival used to fall on the Spring equinox. Passover is a different holiday celebrated by a different religion and is still called its original name which is Pesach (meaning: the mouth speaks).
Jesus observed Passover, as he was Jewish. Easter did not exist then. It was his resurrection that created Easter.
I think Easter is the following Sunday after Passover.

The passover; the feast of Easter.

The orthodox Easter is celebrated on different dates as Easter in Australia because the orthodox religion follows the Jewish. This is the Sunday after the Jewish Passover and when the hours in the day are equal to the hours of the night called the "Equlbruim". The Sunday ( a week after the Jewish Passover) is called Palm Sunday for the Orthodox Christians. The Orthodox Christians use this tradition because that is the way it hs been instructed in the Bible.
Passover, lenten, paschal, quadragesimal...
Easter is observed around the same time as Passover.
The Passover is still the Passover, or Pesach, to the Jews. In the Christian calendar, Good Friday which is observed two days before Easter Sunday, falls at the same time as the Jewish Passover.
"Paschal" is derived from the Latin word "Paschalis," which refers to Easter or the Passover. It is often used in relation to the Passover feast or Easter celebration in Christian liturgy.
In 2010, Easter Sunday was the 6th day of Passover. Those often seem to occur close to one another. Wonder why that is.
