It is likely that the first celebration of the Christian commemoration of Holy Thursday in the San Fernando Valley took place in the Spring of 1798. Father Fermin Lasuen established the Mission San Fernando Rey de España in September of 1797, and the first Maudy Thursday would have been in the following year.
Holy Thursday marks the last Seder dinner of Jesus with his disciples. It is most famously depicted in the painting of the Last Supper by Leonardo da Vinci. An enormous painting of the Last Supper can be seen at Forest Lawn Cemetery in Glendale. When the first Passover was celebrated by Jews in the San Fernando Valley is not known. During the Spanish era celebrating Passover would have been a very dangerous thing.
