Great execution. Interesting to think about the peaks and troughs of global activity.

The Sleep numbers make a big claim: Right after Europe and West Africa have woken up (i.e. now) it says only 350 million people (4.25%) are sleeping. It's 01:08 in Anchorage and 06:08 in Recife. Over 1 billion people live in the Americas between these two time zones. Seems implausible that only a third of them are sleeping?

I think this is just going off sunrise and set +- some estimate. Which does not work as well the farther from the equator you get. It's light for hours up here before you wake, and we sleep like 2-4 hours after sunset.
