First up is a graph of minutes of daylight per day versus time of year.

Delft gets over 1,000 minutes of daylight per day in the middle of the summer. Or, rather, the cloud-layer over Delft gets this daylight. Boston and Cedar Rapids only have small differences in daylight per day.
I was wondering how much less daylight Delft gets per year than Iowa, and to my surprise, Delft gets more daylight!


The second graph is a zoom of the previous graph. As you can see, Delft gets roughly one more day of daylight each year than Cedar Rapids and Boston.
I am looking forward to the days following the Equinox here. One thousand minutes of daylight. Sounds like a novel.
