An approach for making shifted schedules from a regular or master schedule of a building automation system. Shifted schedules may be obtained by applying shifts to the scheduled-on and scheduled-off periods of the days in the master schedule. One set of shifts may apply uniformly to all days of the week or several sets of different shifts may apply to various days of the week. Special events with certain scheduled-on and scheduled-off periods and assigned to particular days may override the regular scheduled-on and scheduled-off periods of those days. The shifted schedules may also contain special events with their periods shifted. The master schedule may govern the regular operating hours of a building and the shifted schedules may control, for example, HVAC equipment in particular zones, certain employee areas, parking lot lights, and so on. Changes to the master schedule may be applied as updates to the shifted schedules.
