This article mainly realizes the time and the date demonstration and the timing function by the software programming, does not have the use special clock chip, the hardware circuit to be succinct, uses the primary device to be few, the cost is low. The hardware part divides into CPU, the pressed key electric circuit, the reset circuit, the display circuit as well as the electrical power system electric circuit. The software part divides into the master routine, the timer interruption subroutine, the demonstration subroutine as well as the timing subroutine.

In this paper, to software programming to realize the time and date when the display and transfer functions, to use a special clock chip, hardware circuit is simple and components used by the less, cost less. Hardware into CPU, keys circuit, reset circuit, show circuit and power supply system circuit. Some software is divided into the main program, regularly interrupted routines, routines and show-time routines.
