In an elegant phenomenon of the world, mechanical applications are replaced by electronic appliance. Especially digital clocks are smart application due to precisely time display and several types of reasons such as much reliable, free maintenance, portable, elegant outlook, inexpensiveness, tiny size and result accuracyy. Every electronics based modern real life application in any filed is now integrated with the digital calendar to enable the user to keep time and date anywhere at any time. It is often incorporated into all kinds of devices such as transports, traffic signal, radios, televisions, standard ovens, computers, laptop, cell phones and wireless peripheral to intellect the device in the way that would be easily enticed by human mind. Regarding the demand of digital clock, this paper presents graceful design of smart digital clock in a particular way that would not only be able to display time, it has an ability to display day of a week with real time. This research shows an embedded system which is constructed through PIC 16F877A microcontroller, DS1307 RTC and 74LS138 decoder IC.
