Related to Passover (the Jewish holiday) or Easter (the Christian holiday).
From Latin 'paschalis', from Hebrew 'Pesach' (Passover). The word entered English through ecclesiastical Latin and has referred to the Christian Easter celebration since the early Middle Ages.
The word 'Paschal' connects two separate religions because historically the Christian Easter was calculated to occur near Passover, so they shared the same lunar calendar calculations despite being different holidays.
