The computus Latin for ‘computation’ is a calculation that determines the calendar date of Easter. Determining this date in advance requires a correlation between the lunar months and the solar year , while also accounting for the month, date, and weekday of the calendar.

Easter is one of the festivals which tries to harmonise the solar and lunar calendars. As a general rule, Easter falls on the first Sunday, following the first full moon after 21 March. But not always. Easter is the time when Christians celebrate the Resurrection of Christ. According to the gospels he was killed three days before the Resurrection, around the time of the Jewish Passover. So Christians wanted to have their feast day around the same time as the Jewish festival which was fixed by the first full moon following the vernal equinox — the spring day when night and day are exactly the same length.

The problem comes because a solar year the length of time it takes the earth to move round the sun is days, 5 hours, 49 minutes, and 12 seconds whereas a lunar year is Calculating one against another is seriously complicated.

The calculation of Easter is complicated because it is linked to an inaccurate version of the Hebrew calendar. Jesus was crucified immediately before the Jewish Passover, which is a celebration of the Exodus from Egypt under Moses. Celebration of Passover started on the 15th day of the spring month of Nisan.
