The declination of the sun varies between the Tropics of Cancer and Captricorn delending oin the time of year.  This is a measured fact.&lt;br /&gt;
This is the approximate formula for the declination of the sun:&lt;br /&gt;
&lt;br /&gt;
S_dec ~=  23.45° x sine( 360°/365 x (d - 81) )&lt;br /&gt;
Where: d is the day of the year.&lt;br /&gt;
&lt;br /&gt;
So, for December 2024 solstice:&lt;br /&gt;
* January: 31&lt;br /&gt;
* February: 29 → total 60&lt;br /&gt;
* March: 31 → total 91&lt;br /&gt;
* April: 30 → total 121&lt;br /&gt;
* May: 31 → total 152&lt;br /&gt;
* June: 30 → total 182&lt;br /&gt;
* July: 31 → total 213&lt;br /&gt;
* August: 31 → total 244&lt;br /&gt;
* September: 30 → total 274&lt;br /&gt;
* October: 31 → total 305&lt;br /&gt;
* November: 30 → total 335&lt;br /&gt;
* December: 21 days → total 356&lt;br /&gt;
&lt;br /&gt;
Applying the formula:&lt;br /&gt;
* S_dec = 23.45° x sine( 360°/365 x (d - 81) )&lt;br /&gt;
* S_dec = 23.45° x sine( 360°/365 x (356 - 81) )&lt;br /&gt;
* S_dec = 23.45° x sine( 0.98630137° x (275) )&lt;br /&gt;
* S_dec = 23.45° x sine( 271.23287671° )&lt;br /&gt;
* S_dec = 23.45° x -0.9997685&lt;br /&gt;
* S_dec = -23.44457137°&lt;br /&gt;
&lt;br /&gt;
For December 15, 2024: −23.37°&lt;/div&gt;</summary>
