Latest dawn in years

This morning's sunrise in Chicago, at 7:26, will be the latest until 6 November 2021. It is not the latest possible sunrise; that would be the one we'll have at 7:29 on 6 November 2027 (and had on 5 November 2016).

I do not really understand the law passed in 2007 that moved our return to standard time from October to November. Who wants to wake up before dawn? Not me.

Tomorrow the sun rises at 6:28. (I will probably do the same around 8.)
