Hàlsun

Hàlsun pronounced: Hal-sun

Hàlsun is the .25 day or half day that occurs at the end of each Martian Month. It is called Hàlsun (based on the phrase “half-sun”) and is celebrated as a holiday where Martians sleep for the half day, then awaken and party hard till the sun comes up again.

There are 57.25 days in a Martian month and the calendar is remotely based on the old Earth Gregorian Calendar.

Seasons: 4

Months in a year: 12

Earth days in a Martian Year: 687 (Martian days are called Sols)

Sols in a month: 57.25

Sols in a week: 12

Hours in a Sol: 26 - technically a solar day lasts about 24 hours, 39 minutes, and 35 seconds on Mars, which can be rounded up to 25 hours a day. This was the original Sol time per day prior to Mars’s colonization. However, the Emperor decided that there will be 26 hours in a day. Leron wanted the clocks to go from 1-13 because it looks cooler and it meant the Mars clocks would be different than the Earth clocks. That and he and his Martians get 1 hour 21 min and 25 seconds a day to sleep or to do whatever. When the Martian clocks strike the 13th hour, time “stops” for the hour and 21 minutes, before the clocks reset and tic again.
