This paper describes the development of microcontrollerbased intelligent electronic calendar, the calendar to realtime display of the calendar year, month, day, minutes, seconds, and the corresponding lunar date, also be measured in real time to take the ambient temperature, use the remote control its remote operation. The hardware part of this system on AT89C52, AT89C2051 microcontroller, clock chip, temperature sensors and other ponents, the paper gives a detailed hardware design and related circuit。 The software part consists mainly of the Gregorian calendarlunar calendar algorithm design module, display module, the time to read, the temperature detection module, infrared transmit and receive modules, etc., are given in the software program of a software program flowchart and functional modules list, and finally the overall system design and implementation, simulation and debugging process, given the next step in the improvement program.
