I will be travelling in February and March to airports that I rarely visit. I usually like the aisle seat but want a window seat if there is something to see. Sometimes I like to look at an airport that I rarely fly to.

Does anyone know of a website where the sunset and sunrise times are given for different months of the year.

If not, care to comment?
