Erastide is a celebration of the day on which the Seven Gods created the world. Greetings ("Joyous Erastide") and gifts are exchanged, and feasts are held. It is a nearly-universal holiday, celebrated in almost all of the major cultures of the world of the Belgariad.

Erastide also marks the beginning of a new year.

Sendarians also invoke blessings from all the gods.
