The term used in Mexico is "Domingo de Resurrección," which translates as Resurrection Sunday. In the United States, many Christian churches continue to prefer the word Easter due to familiarity; however, Resurrection Sunday has gained favor in some Protestant churches in recent years, to counter the possibly pagan origins of the name "Easter."

It is by far the most important date in Christianity (even among churches which don't follow a liturgical calendar), due to the Resurrection being the event on which Christianity either stands or falls. Also, it is usually the date on which church attendance is the highest, resulting in churches often having additional services to handle the crowds (which also gives rise to the term "Easter and Christmas Christians" to define people who only attend on those days). Because Jesus rose from the dead at sunrise on Sunday morning, "sunrise services" are observed in some churches as well as in community gatherings.
Origin of the name "Easter"
The term "Easter" is likely derived from Eastre or Isthar, who was the pagan goddess of fertility for whom the Festival of Ishtar was celebrated each spring. Others suggest that the word comes from the Anglo-Saxon word for "passover". In biblical times the Jewish Passover, which commemorates the sparing of the Hebrew firstborns, was celebrated at roughly the same time as the vernal equinox or this "Easter" festival. The theory of pagan origin surmises that while the Gospel was being spread to the pagans, the celebration of Isthar/Eastre and the celebration of the resurrection became combined and the Christians adopted the name that the pagans had used for their festival.
Date of Resurrection Sunday
Unlike Christmas, which falls on a specific calendar date (December 25 in the Roman Catholic and Protestant traditions; January 8 in the Orthodox ones), Easter/ Resurrection Sunday is considered a "moveable feast" in Christian liturgy, as its date depends on astronomical events.
The First Council of Nicaea in 325 AD set only two rules for its calculation: 1) that the date would be independent of the Hebrew calendar used by the Jews and 2) that it be held on a uniform date throughout all Christian churches.
However, the Council did not specify how the date was to be calculated; the computational process (formally called the comptus) took centuries to formally develop:
- Bede the Venerable would, 400 years after Nicaea, set forth the general rule of the comptus: "The Sunday following the full Moon which falls on or after the equinox will give the lawful Easter."
- Bede's rule would be modified to specifically define two components needed to calculate the date: 1) the term "full moon" would be defined, not as the actual date on which the moon is full, but instead as the 14th day of the lunar month (formally called the "Paschal full moon", taken from Pascha), and 2) the Spring Equinox would be fixed as March 21 (the astronomical March equinox can take place on March 19, 20, or 21).
- The Metonic Cycle, a period of approximately 19 years when the phases of the Moon recur at the same time, would then be used to determine when the Paschal full moon event took place, and from that date the date for Easter/Resurrection Sunday would be derived.
However, Eastern Orthodox churches use the Julian calendar to determine the date of the Paschal full moon, while Western churches use the Gregorian calendar. This results (most years) in differing dates for the two Christian branches. Due to the complexity of the calculations, many websites exist which perform the calculation for both Orthodox and Western churches; one is provided in the External Links below which can also be used to determine the date of Passover.
The next Easter/Resurrection Sunday will be on March 31, 2024.
Use in determining other dates
Many Christian holy days are calculated based on when Easter/Resurrection Sunday is determined:
- Silent Saturday is observed on the day before.
- Good Friday is observed two days before.
- Maundy Thursday is observed three days before.
- Palm Sunday (which is the beginning of Holy Week) is observed the Sunday before.
- Ash Wednesday (the first day of Lent) is observed 46 days before.
- Shrove Tuesday (the day before Lent begins, also known as Mardi Gras) is observed the day before Ash Wednesday.
- The Feast of the Divine Mercy is observed on the Sunday after.
- Pentecost is observed on the seventh Sunday after.
- There are two equinoxes on Earth annually, one in March and one in September; Bede referred to the one in March. The March Equinox is known as the Spring (or Vernal) Equinox in the Northern Hemisphere, and the Autumnal Equinox in the Southern Hemisphere. (An equinox is the instant in time when the plane of the Earth's Equator passes through the geometric center of the Sun's disk, and only occurs in March and September.)
- This is because the Julian calendar adds a leap day every four years without interruption, while the Gregorian calendar modifies that to maintain consistency within the seasons, to skip the leap day in years evenly divisible by 100 (e.g. 1900), except that if the year is evenly divisible by 400 (e.g. 2000) the leap day is retained.
