The moon is a whole new family of calculations, perhaps best left to the rabbi, imam or Pope!
Interestingly, there is such a class for PHP: Moon Phase

I guess you can get very close with UNIX time, a sine function and the right floating point factor, but if your calc puts Ramadan, Lent, Rosh Hashanah a month off because it varies by observation longitude and such and occasionally comes very close to falling either way . . . . Linux

Your utility assumes a 32-bit time type, and has lots of bugs on 64-bit platforms where the 2038 limit no longer applies; but is so complicated I'm not sure where to begin fixing it. I've fixed it to the point where it outputs random times instead of segfaulting..

I agree -- it's very frustrating to work with bash after enjoying the features of Kshell.

If anybody is interested in keeping up with Kshell or AST (a set of software tools from AT&T Labs Research) you can join one of the mailing lists listed on this page:

AT&T Research AST and UWIN mailing groups

I think this is a worthwhile mailing list to belong to.
