Sunrise chart for Chicago, 2007

It's time to update the sunrise chart. (You can get one for your own location at http://www.wx-now.com/Sunrise/SunriseChart.aspx.)

Notice that in 2007, Daylight Saving Time lasts a lot longer than in years past: from the second Sunday in March through the first Sunday in November. This actually makes the autumn a little darker, as you can see from the chart.
