In the calendar used by the ancient cultures of the Lagendeda River, the new year started on the fall equinox. This was when the land was recovering from the dry heat of the summer, and farmers were beginning to plough their fields in time for the autumn rains.
In Muipidan, the day was known as mesündede ne-thendede [ˈme.zʏˌⁿde.də nɛˈtʰɛ.ⁿdɛ.də], which just means “beginning of the year”. The word mesündede is literally “the spring” (the kind that emits water), but it’s often used to mean the source or beginning of something.
In Kharulian, the day was called ighwilwi mwéefanat [iˈɣʷi.ɫi ˈmˠeː.ɸa.nat], which means “the night’s overtaking”. They pictured the day and night battling for control of the sky, and the fall equinox was when the night gained the upper hand.
