Thanks for the compliments, but as you can see in the header of the
program,
it is only an Euphoria translation of a C program by someone else. The
program
can of course be changed in such a way that it only says 'new moon' when
the
moon_age is 0, etc.

How did you calculate this by 'brute force'? Is there an algorithm
different from the
one used in moon_age?
