Calendar

Halkegania uses an 8 day week. One of these days is the Day of Void, a holy day of rest.

Four weeks makes up a 32-day month.

There are 12 months in a year, giving Halkegania a 384 day year.

It is unknown if the length of a day is different than that of an earth day. Saito certainly never noted a difference.

Halkegania uses the conventional 12-hour clock to measure time.

Summer vacation at the Tristan Academy is 2.5 months, or 80 days long.
