Easter Sunday celebrates the resurrection of Jesus, according to Christian belief. The Easter date depends on the ecclesiastical approximation of the March equinox. In 325CE the Council of Nicaea decided that the Easter date would be the first Sunday after the first full moon occurring on or after the March equinox. Easter is therefore delayed one week if the full moon is on Sunday, which lessens the likelihood of it falling on the same day as the Jewish Passover.
Higan, or Higan-e, is a week of Buddhist services observed in Japan during both the spring and autumn equinoxes when day and night are equal at length.

After the war, when the national holidays were renamed, they became simply spring and autumn equinoxes.
Higan is a one-week period surrounding the spring and autumn equinoxes. It means the “other shore” and refers to the spirits of the dead reaching Nirvana after crossing the river of existence.

Buddhist prayers, rice balls and sushi are offered. This is a time for the Japanese to worship their imperial ancestors and to welcome spring.
