I'm not sure I asked the correct question. I am trying to learn when our sun is at solar 12 noon on my yard, does the sun light travel a perfect path across earth, 50% before solar 12 noon and 50% after solar 12 noon.
I built a large sun dial in my yard 3 ft tall 6 ft long. I used a compass to line it up magnetic north south. Should I have used True north to line up sun dial instead of magnetic north?
The numbers that I have do not match up with online information of where solar 12 noon is at my house???

Dec 21 30.5° 29.15°
Jan 21 38.4 33.32
Feb 21 43.4 42.63
March 21 54.0 52.73
April 21 65.4 62.83
Sun dial says solar 12 noon is 11:55 am CT at my house. Daylight saving time 12.55pm
Online info was solar 12 noon at 11:55 am but this month of April solar 12 noon is 11:45 am. How is that possible or is that an error.
NEXT: Online research shows if a farmer plants a 1000 acre field with north south rows and another identical 1000 acre field with east west rows, the north south crop will be a $30,000. more profit than the east west row crop. Research says east west rows never has full direct sun on the north side of the plants.
I have a home garden. I am trying to be accurate as possible. Can I rely 100% on my sun dial to tell me sun really is solar 12 noon at 11:55 am? Is it correct for crops to line up with magnetic north south OR should crops be lined up with True north.???
Should I use magnetic north of True north for my sun dial?
