ScreenTinker 832a9c9bb2 Draw a schedule that runs past midnight ... 10pm to 4am is an ordinary signage schedule and the playback engine has always understood it — schedule-eval treats an end before a start as a wrap. The calendar did not. It computed four minus twenty-two, got negative eighteen hours, and drew an eighteen-pixel sliver at 10pm with nothing at all after midnight. The schedule played correctly while appearing broken. An overnight window is now split into the pieces a week grid can draw: the part before midnight on its own day, the part after it on the next, squared off where they meet so they read as one window rather than two schedules. The tooltip names the whole span, since neither half shows it alone. A Saturday night spill is simply not drawn rather than wrapped round to Sunday, where it would appear to have played six days early. Dragging one is refused. A drag describes a window inside a single day, so applying it to a wrap would clamp it into that day and silently destroy the schedule — the same reason a recurring schedule's day cannot be dragged. Verified in a browser against a real 22:00 to 04:00 schedule: 88px on Tuesday night, 176px on Wednesday morning, alongside an ordinary daytime block.
