The Sun

 

The length of daylight grows nearly 90 minutes during April.  By month’s end, the sun is in the sky for almost 14 hours in the Chicago area.  Now rising north of east and setting north of west, the sun’s daily arc across the sky grows longer each day with about 3 minutes added each day.  The blue area on the chart above shows the daylight during the month compared to the bell-shaped curve that indicates the length of daylight for the entire year.
