I was checking the sunrise to sunset sun angle for solar panels. I found very interesting the sun angle stays steady for a week during the solstice (Summer/Winter). During the days between the sun angle increases and or decrease every day or every couple days. On the 18th is drops to 27.5 for the Cincinnati area and stays at 27.5 through 25th. That is 8 days. This does not fit a round globe mathematics. On the 25th to 26th the sun angle starts to increase.

My 2nd question is why doesn't the calendar new year start in the 1st day the daylight time increases on the 21st or the 25th when the sun starts in the rise angle. So 21st or 25th day should be January 1st. Why is January 1st later? This same thing happens the third week of June. Why doesn't the calendar follow the sun dates?
