With a view to display a Digital Clock through digital circuits using modulo-n (mod-n) counters, a circuit diagram was designed and implemented it through multi simulation software. In the similar manner the time digits were displayed on seven segment displays at 8255 programmable peripheral interface (PPI) ports through 8051 microcontroller, the time digits (hours, minutes and seconds) were connected to the first 8255 PPI and the date digits (Years, months and days) were connected to second 8255 PPI. The detailed circuit diagram was given to understand the construction details of the circuit. The loop in a loop technique of assembly language program was used to display date and time. After displaying a year, month and day on the date displays through main program, it calls 1day subroutine to display time in 24 hours clock. The 1day subroutine calls 1second delay subroutine to change the digits in seconds display. After completion of 24 hours time, the digit will be changed in the days display to indicate the next date. After completion of 31 days in the first month, the main program calls month subroutine to change the digit in the months display. Precautions were taken to change the digits in months display for January 31 days, February 28 days, March 31 days, April 30 days, May 31 days, June 30 days, July 31 days, August 31 days, September 30 days, October 31 days, November 30 days and December 31 days. After completion of a month, there will be a change in years digit and this process will be repeated continuously.
