History behind why Easter is celebrated on different dates every year

Nyeri Catholic Archbishop Antony Muheria carries a cross as led other faithful in a religious procession to Our Lady of Constanta Cathedral in Nyeri during a past event..Easter holidays are always celebrated over weekends but the exact date changes every year because it is linked to the Jewish holiday of Passover, which is based on the lunar calendar.

According to Christian minister, Mary Fairchild, the lunar calendar is based on the phases of the moon, and it’s about 11 days shorter than the solar calendar we use for our everyday lives.complex system was developed in the early days of Christianity.


It’s based on a formula that takes into account the phases of the moon and the Spring Equinox.

The Spring Equinox is the day when the length of day and night are equal, and it marks the beginning of spring in the northern hemisphere.

The formula used to determine the date of Easter was established at the Council of Nicaea in 325 AD.

The council decided that Easter should be celebrated on the first Sunday after the first full moon occurring on or after the Spring Equinox. This means that Easter can fall on any Sunday between March 22 and April 25.


This system is known as the Gregorian calendar, and it’s used by most countries around the world.

However, some Christians in Greece, Cyprus and Romania use the Julian calendar, which is older and less accurate than the Gregorian calendar.

This means that they celebrate Easter on a different date than the majority of Christians.

While majority will start Easter celebrations with Good Friday on April 7, they will begin on April 14.
