Sunrise and Sunset

I like to keep track of when the sun is going to rise and set. I like to know how many hours of sun (or lack of it since I do live in Rochester ;-P) we are expected. We gain 2-3 minutes of sunlight every day from Dec 21 to Jun 21. Here's some links to sites that list this info for our area.
