This paper presents the design and simulation of Microcontroller based Electronic Calendar using Circuit design suite- MULTISIM. Paper calendar has been in existence and is used manually to keep date of each week of the month every year. The emergence of electronic calendar has taken precedence over the paper type. Every electronic device is now integrated with the electronic calendar to enable the user to keep time and date anywhere at any time. This report would enable user to understand the foundational design of the electronic calendar through simulation. 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. Digit numbers that represent time, date, month, and year were written in assembly language and tested. The simulated system displays accurate time of the day, day of the week, its date, month and year. 8051 Microcontroller controls every unit and the result is shown to the user through seven segments display.
