There 8 days in a week, 32 days in a month and 11 months in a year. The 12th 'month' is only 13 days long and 14 days long on a leap year.
It isn't very inventive, but it works for the Qatama.
This chart showing how the Qatam calendar corresponds to the Gregorian (non-leap year), note the use of colors to show weeks.
Each week has a color and named accordingly, i.e. red-week = galam koga.
