There is a calculator that can help you determine when civil twilight
is based on the date and your location.

I use the one year version, print it out and keep a laminated copy in my
flight bag. Very handy: <http://aa.usno.navy.mil/data/docs/RS_OneYear.html>

I also keep the rise/set times for The Moon as an aid when doing night
currency. I like to do the currency both when The Moon is full as well as
when it's not there.
