A programmable electronic real-time load controller includes: a plurality of load control circuits, each being adapted to be interconnected with a load; a hardware clock; and, a programmed data processor for responding to real-time information from the hardware clock to effect control of the status of each load control circuit in accordance with a predetermined time schedule that has been entered into the data processor. The data processor includes: a CPU; a program memory; an event memory; and a plurality of ports which permit a plurality of devices, including a keyboard, a plurality of displays, and the hardware clock, to interchange information with the data processor. The event memory includes a plurality of event memory locations for storing one or more control events and corresponding event times for each load. The CPU is operative: to enter control events and corresponding event times, upon actuation of the keyboard, into the event memory; to obtain real-time information from the hardware clock; to address and search the event memory locations to effect comparison, for each load, of the event times therein with the real-time information; and, to control the status of each load control circuit in accordance with that one of the control events whose corresponding event time occurs at or immediately preceding the time represented by the real-time information.
