None such within Guide, I must confess. I've been asked to add
such a feature for arbitrary objects, but it's been on my to-do list
for a very long time.

The closest I can suggest is this. Some modest knowledge of C is
required: I've posted most of the 'basic astronomical functions'
source code for Guide at

http://www.projectpluto.com/source.htm#astrocalc

It can be compiled for Windows or Linux. As an example of how the
functions work, there's a 'riseset3' program which does exactly what
you suggest: given a location and a particular month or year, it
outputs a table of sun and moon rise/set times for that month or year.

If you're a programmer, this is exciting because you can revise this
to do exactly what you want. If you aren't... well, I hope somebody
else can make use of it.
