Can a schedule window run overnight, past midnight?
Yes. A window can start in the evening and end the next morning, for example 9 pm to 6 am. Skie treats it as one continuous window, so night mode or a bedtime lock does not need two separate entries or any workaround at midnight.
Many real rules cross midnight. Hostel lights-out, a child's bedtime, a night shift handover. Skie lets a window's end time fall before its start time and understands that as running through the night into the next day.
You choose the days the window starts on. A window starting on a school night at 9 pm and ending at 6 am covers the hours until morning. If weekends differ, add a separate window with its own days and times. Because order matters, put the more specific window ahead of the broader one, as the first matching window wins.
Overnight windows depend on a correct clock. Date and time are locked to automatic, with automatic time zone forced on, so changing the clock to escape the window is not possible from Settings. If a tablet has been offline, it still uses its cached schedule against the device clock, and syncs as soon as the network returns.
A common use is hostel night mode, where only calls and a clock are allowed after lights-out, with the rest hidden. Another is a company that wants delivery phones to switch to a narrow app set outside shift hours. A practical tip: check the boundary times on a pilot device, watching what happens at the exact start and end, before you roll the schedule out to every tablet.
