How to find true north vs magnetic north? Online information says magnetic north moves around as much as 2.5 degrees. Lots of information online about true north 1 place save 5 degrees off magnetic, another place says 10 to 12 degrees, another place 10 to 25 degree, another place 15 to 30, another place says true north is 45 degrees from magnetic north. Another place says true north lines up perfect with the north star all calculations are taken from the north star. What I am trying to do is find out, when is the SUN is exactly straight up at my house. I used a compass to find magnetic north then hammer a steak in the ground when the suns shadow lines up with magnetic north sun it straight up with magnetic north but not with true north. Magnetic north shows sun is straight up a 1:12 pm at my house. Seems to me I read someone where magnet north vs true north is about 23 degrees but with a fluctuation of 2.5 degrees what does that really mean. Another place I read magnet north vs true north is at maximum angle at the north pole the closer you get to the equator the lower the angle. There is so much BS online these days no one knows what to believe. If I knew sun rise and sun set I could calculate the 1/2 point and know when sun is straight up. I do know sun rise was 5:03 am June 22 but never could find out what sun set was. I know from watching the sun it sets about 8:30 pm. Convert 8:30 to a 24 hr clock = 20:30. 5.03 + 20.30 = 25.33 / 2 = 13.34 convert back to 12 hr clock = 1.34 pm I have no clue how accurate this is. 1.34 pm is more accurate than 1:12 pm. My zip code is 37129 there may be a place to look up information by zip code for, sun rise, sun set, high noon but I have not found it?
