Rotating days, drop schedules and A/B blocks.

Draw your rotation once. nOS checks each class only against classes that meet the same day.

How a rotating day works in nOS

  • Each day is its own slot.

    A Day 2 class is checked only against Day 2. A teacher free on B day is really free.

  • The dropped block is free.

    In a drop schedule, the missing block’s teacher and room are free that day.

  • Name your days.

    Cycles run up to 20 days, named Day A to F, 1 to 6, or Gold and Blue.

Pick your schedule type.

School setup offers same every day, A/B days, 4×4 block, rotating or drop, modified block and flex mods. Bell times can differ by day.

Questions about rotating schedules

Which schedule types does nOS support?

Same every day, A/B alternating days, 4×4 block, a rotating cycle, a drop schedule or flex mods, with starting points like modified block and waterfall.

Can nOS handle a seven-, eight- or ten-day rotation?

Yes. A cycle can run up to 20 days and keeps the day names you give it.

Can one block meet twice in a day?

Yes. Put the same block in two slots of a day, and every class in it meets at both times. A lab or help block only some students return to is a block of its own.

How much does it cost?

nOS is priced per enrolled student per year, and the rate steps down as a school grows. There is no setup fee. See the price for your school.
