I'm working on site that let's you check when a manned space station was last directly over your house.

It's a reference to https://xkcd.com/2883/, which I've always liked and was suprised there was no tool to check when you last had astronauts over for dinner.

Looking up the location of the ISS at a specific time is easy. Looking up the closest passes of the ISS to a specific location for the last 30 years on-demand is more complicated.
