There are twelve months in the Achaean year. These are:
Sarapin (mid-winter) Daedalan (late winter) Aeguary (early spring) Miraman (mid-spring) Scarlatan (late spring) Ero (early summer) Valnuary (mid-summer) Lupar (late summer) Phaestian (early autumn) Chronos (mid-autumn) Glacian (late autumn) Mayan (early winter)
Each month is made up of 25 Achaean days, which are roughly equal to one real-life hour.
