The name is from the Chaldean Akkadian and Sumerian for "[[barley]]", originally marking two festivals celebrating the beginning of each of the two half-years of the Sumerian calendar, marking the sowing of barley in autumn and the cutting of barley in spring. In [[Babylonian religion]] it came to be dedicated to [[Marduk]]'s victory over [[Tiamat]].
Following the first new moon after the vernal equinox in late March, the Chaldean Babylonians of Mesopotamia would honor the rebirth of the natural world with a multi-day festival called Akitu. This early New Year’s celebration dates back to around 5700 B.C., and is believed to have been deeply intertwined with religion and mythology. During the Akitu, statues of the gods were paraded through the city streets, and rites were enacted to symbolize their victory over the forces of chaos. Through these rituals the Babylonians believed the world was symbolically cleansed and recreated by the gods in preparation for the new year and the return of spring.
