Shaded non-working days on the chart

Days nobody works are shaded behind the bars, so a bar running through a weekend is visibly wrong.

What it is

Vertical shaded bands drawn under the grid and bars for every non-working day in the company pattern. Consecutive off days (Sat+Sun) merge into one band so no seam shows. Only drawn at day/week zoom.

Also called: weekend shading · grey bands on the schedule · days nobody works

How it works
  1. 1offBands walks the visible day range, opening a run at the first non-working day and closing it at the first working day or the range end
  2. 2Bands come from the COMPANY pattern, because one background can only tell one story
  3. 3A Saturday crew simply has bars crossing the band, which reads correctly as 'this crew is working when others aren't'
  4. 4Suppressed below 8 pixels-per-day — at quarter or year zoom a weekend is a sliver and seven bands per inch is noise
Why we built it

Fixing the date arithmetic left builders taking the schedule on faith — the maths was right, but nothing on screen proved it, and a builder burned once by a plan that ran through weekends does not trust the next one. Weekends and days off are shaded down the board, so a bar crossing a shaded band is visibly wrong. The schedule can be checked at a glance instead of audited stage by stage.

The problem
  • Impossible schedules looking exactly like possible ones
Sound familiar?
What you get
Wrong dates are visible instead of needing an audit
No visual noise at wide zoom levels
