The real daylight saving

A friend on social media posted a graph of how quickly or slowly the amount of daylight changes per week. Unfortunately the graph was for London, and pretty ugly, so I decided to make one for Chicago that was a bit more spare:

Here in Week 6, we get 15 more minutes of daylight than we got last week. For most of March, we'll get 17 minutes more per week before things slow down a bit, then reverse. The weeks of both solstices have zero change.

The friend wondered in her post what it would look like in the southern hemisphere. So, voilà Sydney:

And just for giggles, I graphed Fairbanks, too:

Neat, huh?
