The Halkeginian calendar, or the calendar of Brimir, consists of 384 days, divided evenly into twelve months of 32 days, which are divided into four eight-day weeks. One of the days of the week is the Day of Void, a holy day of rest.
Since it's not known how long each day is, it is not possible to compare the length of a Halkeginian year to an Earth year. However, Saito never notes much difference. Halkegania appears to use the conventional 12-hour clock to measure time.

Many names are uncertain because they're not given in their original language.
Some discrepancies are: Nyð and Ansuz(?) are both the eighth month; Mann and Lagu are both the fourth day; Tir/Týr and Tîwaz are etymologically same, yet are a month and a week, respectively; Hagall is both a month and a day.
What can be reconstructed are: The fifth and twelfth monthes are Ur/Úr and Wynn, respectively; the first, second, third, and fourth weeks are Frejya, Heimdallr, Eolh, and Tîwaz, respectively; and the seventh day is Éðel(?). Additionally, the eighth month is in the summer; Ior/Yule(?) is in the first half of the week; and the Day of Void is a day of rest.
