The system is divided into different units and all work in hand to ensure its accuracy and efficiency. An oscillator that clocks the 8051 is externally interfaced and operates at 10.2MHz. The control unit of this system is 8051 Microcontroller through which every other unit is controlled. Machine, Latch, decoder, seven segment display, LEDs, Transistor,Ī Microcontroller based Electronic Calendar (MBEC) is a system that provides accurate time, day and date of each day in a week for many years to the user. Keywords- 8051 Microcontroller, EPROM, Assembler, Programming 8051 Microcontroller controls every unit and the result is shown to the user through seven segments display. The simulated system displays accurate time of the day, day of the week, its date, month and year.

Digit numbers that represent time, date, month, and year were written in assembly language and tested. The system design was achieved by dividing it into five modules namely power supply, 8051 control system, select and set, day and date, digital clock display. This report would enable user to understand the foundational design of the electronic calendar through simulation. Every electronic device is now integrated with the electronic calendar to enable the user to keep time and date anywhere at any time. The emergence of electronic calendar has taken precedence over the paper type. Paper calendar has been in existence and is used manually to keep date of each week of the month every year. # Department of Electronic & Computer Engineering, University of Port Harcourt, Rivers State, Nigeria * Department of Computer Engineering, Enugu State University of Science & Technology, Enugu State, NigeriaĪbstract - This paper presents the design and simulation of Microcontroller based Electronic Calendar using Circuit design suite- MULTISIM.
