I have a calendar question.......Does anyone here chart the sun to pinpoint the spring equinox? I started to think about this after I saw a post about it.
Should we just take NASA's word for when the equinox happens, or should we actuality chart it for ourselves?
Just some early morning thoughts. I would love some thoughts from others that follow the same calendar.
