Each square is one class period. Squares fill in from the bottom up as the period happens — empty means upcoming, solid grey means done, and the current period fills live in accent color.
Progress shows completion bars for the academic year, current semester, quarter, week, and today.
Continuous is every period of the year in one grid, no gaps between days. Hover a square to see its date and where it falls in the semester/year, and to light up the rest of that day's periods.
Weekly lays the same data out as one row per week, Mon–Fri as columns, so short weeks (holidays, breaks) show up as visibly empty columns. Hover an empty column to see why there's no school, and hover a period to light up its 7-period rotation cycle across days.
Current Period is just the one live progress bar, full-size — handy if all you want is a glance at how much of the period is left.
Use the ⚙ settings panel to switch light/dark and accent color,
and to filter the grid down to just the periods you teach. Each tab
is linkable — add #continuous, #weekly,
#current, or #progress to the URL to land
on that view directly (handy for a bookmarked start page).
