Dave, the same question occurred to me. I had looked at Table 4 in Pub. 249 and said, "Surely I can come up with something more straightforward than this!" only to discover that I really couldn't.
I worked with this a day or two ago, and decided that while possible, it was not really practical. The two complexities I found were related to:
- the equation of time
- leap years
Stars are simply easier.
