The low-key success of week-number calendars points to what I think was the big reason the Comté calendar never took off: Months are, unless you're working in a maritime environment, an unnecessary intermediary unit of measure, and for most are only valuable for their legacy cultural references. Redefining them should have been a non-starter.

A week-number calendar is great because it's simpler than trying to retrofit a year-month-day structure, yet still allows legacy Gregorian months to be seamlessly overlaid on it. The Intel PDF is a great example of this.
