I've been working on similar, but stripped down (no words for days of week or months, only numeral). The twist is that I am trying to do it as an include file (LOAD) so that it can be a building block for a larger project. My goal is not to display but rather to have the date/ time data for a time-stamp on other data that is saved in EEPROM or Hitt Data logger.
Have you thought about porting this to the LCD AppMod for cheap and small deployment?
Parallax Item code 29121. The mod is only $15 and gives you a 2x8 screen plus four buttons.
Just thinking... Since you have the DS1302 & the light sensor, you could add an EEPROM and every minute around dawn and dusk record the time & light levels. Then you could transfer those data to Excel and get good info for setting the light level you want for the ON and OFF settings.
Also, I'm interested in figuring out how long of a cable (probably CAT5) I can run from my board to a LCD AppMod. I'd like to be able to check on data from my desk rather then the board location. I intend to try a very low baud rate and maybe sending twice with a comparison check. I also might have the SX serial output control a transistor with a higher voltage for the cable.

the LCD AppMod may work for my final project
I want to control an outside light. It comes on when it gets dark (photo sensor)
but can be set to go off later so it is not on all night.

So many ideas...
