Some earth science type questions:

I had thought that days at the equator were exactly 12 hours long all
year round, but charts show varying sunrise and sunset times. How is
that?

When is high noon at 42 degrees north, 76 degrees west?
I came up with 12 + 1/15 = 12 + 4/60 = 12:04pm EST.
Does the latitude come into play at all, or is it just based on
longitude?
