How does pd.date_range() fit in with axs[].set_xticks() ?

So when you call pandas.daterange() you are getting back an array of things that look like 64 bit integers, not strings. Do you want a bunch of really big integers appearing as tick labels?

Definitely not. I'm happy with the way this turns out. I just didn't quite understand how it's working. This helps. Thanks!
