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.
Dashboard is built for a large 16:9 screen — the whole school day laid out as one bar (each period sized to its own length, gaps for lunch/passing time included, a line marking right now), a live countdown to whatever's next, and a few at-a-glance stats below it.
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, #dashboard, or #progress
to the URL to land on that view directly (handy for a bookmarked
start page).
