First of all thanks to your reply and advice.
Sorry for the mistaken. What i mean is c = a.highbyte + a.lowbyte.

I have looked on the datasheet for the PIC16F84A, the space is 64 bytes for eeprom. I know it is impossible for me to store in the 365 data into the eeprom.
Do you have any suggestion?
How about other places such as program memory or RAM?
I am thinking of using PIC16F876 but it is only 256 bytes only.

I just want to store the time(sunrise time) for 365 day to anything places that available so that i can read it thru the date.
for example: 1 jan 06 the sunrise time is 6:10 am
2 jan 06 the sunrise time is 6:15 am
and so on.

Please advice and thanks you very much.....
