Calendar

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.

It appears to be a lunar or lunisolar calendar. It is unknown whether it's a fixed calendar or if there is a leap day, week, or month.

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.

When Tiffania enrolled in the Tristanian Academy of Magic, it was the year 6243.

Summer vacation at the Tristanian Academy of Magic is 2.5 months, or 80 days long.
