The framework of theAbysmal year

Months of the Years

With a collection of weeks to draw on, we can now organize them by month. While we’ve become accustomed to months of about 30 days, other arrangements are possible. theAbysmal Calendar’s months use 3 to 5 weeks of 5 to 13 days. The shorter weeks, i.e. 3 and 4 days, are embedded in 6-, 8-, 9-, and 12-day weeks.

The point at this stage is to arrange the year by even measures.

365 Days

None

364 Days

This particular calendar uses the 7-day week to construct the year, and as such, it harmonizes with the Weekdays.

radial image of the days of the year. The outer circle is made of 13 rectangles. Each rectangle is composed of four by seven circles. Each circle is shaded a colour of greyscale. The colour of the days range from black at bottom through greyscale to white at top. A single black day sits at bottom. The circle inside numbers the months 0 to 12 clockwise from bottom left. The next circle in numbers the quarters 0 to 3, the next circle numbers the semesters 0 and 1. At centre is the number 364.
