Sunset, sunrise, twilight calculations in LC?

[FlexibleLearning.com]

Yes. I have done this. It is not a trivial exercise. It requires a lot of
complex solar geometry calculations as well as Julian calcs.

Go to http://www.esrl.noaa.gov/gmd/grad/solcalc, pick the "Solar
Calculator", extract the javascript in the web page, then translate it to LC
for use in your own work.

You may be some time... I was! :)
