Like today: I wanted to verify the sunrise/sunset times in the year that most of the narrative takes place, and Google sent me to this website by the US Naval Observatory's Astronomical Applications Department, "Sun or Moon Rise/Set Table for One Year". You punch in the year and details for the place you want, and the website generates the sunrise/sunset/moonrise/moonset times for that entire year.
I didn't actually need that much mathematical and geographical accuracy for the scene I'm writing, but it's still pretty cool.
