The line
(date-day quando)99
looks pretty suspicious; with the 99 there, the first branch of the
enclosing 'if' expression returns 8 values but the second branch returns
7 values.

This one got me stumped for a while. I don't remember a case like
this ever occurring in the past, so I'm thinking that maybe this is a
regression?
In DrRacket, with debugging and stacktrace enabled in all the buffers
involved, when I run the file strano.rkt, I get this error:
Welcome to DrRacket, version 5.3.3.3--2013-02-16(1ddacff/a) [3m].

And the region of source highlighted is the let*-values expression
starting at line 28 in strano.rkt.
However, the error is not there: it's in the function
equation-of-time-alt at line 272 in astronomia.rkt, and DrRacket gave
me no hint of where the error actually happened.
If this is what DrRacket always did, I'm surprised I had not stumped
over this before. If it's a novelty, then I don't like it. 8^)
(I'm attaching the two files mentioned, for reference. They are not
compilable alone, because there are other components missing, one of
these being a foreign library. I can supply all of the missing
sources, if requested. I can also supply the library as a win64 dll
(and can compile it for win32 too))
Cheers
