Ah and even moon-rise and moon-set! But it doesn't seem to tell you for any day except today!

But errr... isn't the Weather Underground a domestic terrorism and bombing group?

Contrary to what the others posted, the name is only a reference. The weather service is not a continuation of the earlier group.

It was acquired by The Weather Channel (later The Weather Company) which was later acquired by IBM.

They pivoted to weather data services

It used to be a terrorism and bombing group, but then they pivoted into running a network of amateur weather stations.

(Since the bombing group was underground we can of course never know for sure exactly which members were part of the pivot)
