Because of digital integrated circuit development and wide application of quartz crystal oscillators, the digital clock has become more accurate than the old-fashioned clocks. The digitalization of the clocks has brought great convenience to people, and also greatly expanded the original clock function. Calendar has plenty of advantages such as easy to read, displayed with intuition, low cost and so on. The calendar meet the nowadays development trend of electronic instrumentation, and has a broad market prospect. The design is based on FPGA chip with a high degree of system integration and precision. This design uses Verilog HDL, so it can be flexible and easy to update in the future. The first step of design process is analysis system and determine the systems main function. Then we should draw flow charts of each module and data channels of the system. Finally write the code for each module. This thesis will introduce eight modules of the calendar system individually. Including electronic calendar center control module, Timing and adjustment module,dynamic time display selection module, LED display module, the stopwatch module, date and adjustment module, alarm module and frequency module. The chapter of systems analysis including the overall design of the profile and the description of each module. The chapter of system implementation has a separate section for each module system flowchart and functional bloc
