Each day block carries three data points — date, auspiciousness symbol, and weekday — so the blocks keep their full height. The band renders at the resolution that frames the current span; the selection is dimmed-in (surroundings fade, dates stay readable) and underlined. Four states below. Drag any band to test another span.

A single day selected. The span is under a month, so the band frames the month.

A week selected — still under a month, so the month view holds it.

A full month selected. Over a month, so the band steps out to the quarter.

A quarter selected. Over a quarter, so the band opens to the full year — compact blocks keep all twelve months in view.
