actually you did not edited the code properly.
you removed many things which were necessary for the clock. I am giving you one example...
In your code above there is a mistake..
CODE:
done:
mov sec,#00h ;For more information about the RTC DS1307
mov min,#0h ;Please refer to the datasheet
mov hour,#51h ;21h for 24 hour format
mov days,#01h
mov date,#1h
mov month,#1h

Project Update!
Hello friends,
the new and improved, update of "AT89C4051 as RTC" is available for download. instead of 16x2 LCD i am using 20x4 LCD and with the help of CGRAM area in LCD (type HD44780) i created digits from 0 to 9. which are double the size of the original clock. so clock looks much better and is more impressive.. few more bugs have been fixed.

so give it a try... go to download section and DOWNL...[more]
