Google. Research how digital clocks work. Look for digital watch circuits and datasheets for rtc chips.
When you know how a hardware digital clock works you can look at how to simulate one in software.

The ready made clock chips available, usually use mains frequency as refernce and thus the accuracy highly depends on the same. But you can get dead accuracy with rtc interfaced with a microcontroller. But In the DS1307 as it uses external cylinderical crystal, the accuracy may not be guaranteed. But using a DS12887 module accurate time can (...)

use a timer interrupt(set it at 5) for 12hrs..
it will simply flip the previous state..if it was on at 5am then it will gt switched off at 5pm..and so on..
u may use real time clock and then then check the data and make the further program ....
I agree with beyondH.

First read I2C protocol and datasheet of PIC16F877 its all about there then after understanding the concept of I2C it will become easy for you to write codes for digital clock.
For a short time you can use I2C libraries also which has fully working codes.
Interfacing is quite easy see the link.
