Hello Frank,
The drawing works fine for estimate of the dec. But abouts the dates?
20 mar 0° and 21 jun 23,5° are familiair. But I thought how to memorize the dates between?
12 april, 5 may, 28 may? Then I realized they are 23 days further in date.
Well 23,5° can inform me the dates are 23 days seperated.
Just an idea to remember it.
