With the development of society, science and technology, human beings that time from the view of the sun, the electronic clock pendulum clock to now, continuous research and innovation. At the same time in the observation time in order to understand other human related information, such as temperature, week, date, the birth of the electronic calendar, it set the time, date and week in a body, with easy to read, intuitive display functional diversity simple circuit and many other advantages, conform to the trend of the development of electronic instruments. It has broad market prospects. The electronic calendar based on MCU AT89C51 as the control core, through the MCU to control the clock chip DS1302 read the realization of time。 independent keys to achieve the adjustment of time and alarm time. This paper mainly introduces the circuit design and software design of AT89C51 single chip microprocessor and Dsl302 realtime clock chip. It can display the Gregorian calendar year, month, day, week, hour, minutes, seconds, and can be adjusted according to the needs of each bit. Then SCM control LCD display module to display the electronic calendar, gives the hardware circuit design, software design and programming, through the Proteus software, the simulation of hardware circuit and software programming, has certain practical value. Keywords: SCM。 Proteus。由于電子科技的飛速發(fā)展，尤其是大規(guī)模集成電路的發(fā)展，使得人民的生活發(fā)生了重大改變。所以國內(nèi)在電子萬年歷的開發(fā)過程中遇到了瓶頸，必須要制定正確的發(fā)展戰(zhàn)略。 LED 數(shù)字顯示 的電子歷具有方便讀取、走時(shí)精確、顯示清晰等特點(diǎn)，所以在被引入到各個(gè)電子產(chǎn)
