Why is Easter at a different time each year?

 

Easter is calculated to follow Passover which is based on the lunar calendar.

In 2021, Easter will be on Sunday, April, 4^th.

Catholics and most Protestants use the new Gregorian calendar decreed by Pope Gregory XIII in 1582 to calculate the date of Easter.

The time of Easter is based on the cycles of the moon, the equinox, and seasons and things in nature.

In simple terms Easter occurs on the first Sunday following the first full moon that occurs on or after the day of the vernal equinox (the first day of spring).

In 2021, the vernal equinox was on Wednesday, March 20th. The first full moon after that was on March, 28^th. Thus, Easter will be on Sunday, April, 4^th.

The earliest Easter can be is March 22 as it was last in 1818 and will be next in 2285.

The latest Easter can be is April 25 as it was last in 1943 and will be next in 2038.

What does Corpus Christi mean?

Corpus Christi is one of the biggest festivals of the Catholic Church. At Corpus Christi, Catholics around the world celebrate the “Body of Christ”.

Corpus Christi celebrates the presence of the body and blood of Christ, one of the sacraments of the Eucharist. 

The celebration of Corpus Christi began in 1193, after the initiative of Juliana of Cornellon from Belgium, who claimed to have seen the Virgin Mary asking her to throw a big party to honor the body of Jesus in the Eucharist.

Some years later, in 1264, Pope Urban IV established the feast to the Catholic Church, by the bull Transiturus de Hoc Mundo.
