Holy Thursday, Good Friday, Holy Saturday and Easter Sunday are dates that change every year and there is a historical reason for this.
For Catholics, Holy Week is the most important celebration of the liturgical calendar because the resurrection of Jesus is remembered. In fact, during the first three centuries of the faith it was the only festival that was celebrated.
The origin of the date is due to the fact that the death of Christ occurred near the Jewish Passover. The Gospels refer to this celebration in the biblical passage of the Last Supper, when Jesus meets with his disciples to celebrate the feast in which the Jews remembered his departure from Egypt.
The Jews, according to their rules, must renew this celebration every year on the 15th day of the month of Nisan, which begins with the first new moon of spring: that is, the first full moon of spring, regardless of the day of the week that falls. .
Over time, and although some regions in the world resisted, the Church began to unify the date of Easter. Since the First Ecumenical Council of Nicaea in the year 325, Holy Week has been celebrated on the first Sunday of the full moon after the vernal equinox in the northern hemisphere and the autumnal equinox in the southern hemisphere (around March 21).
At first, it was taken into account that it did not coincide with the celebration of Jewish Passover, but over time this custom was lost, at least in the West.
Most of the time Holy Week falls during the first or second week of April.
