Not a big deal but why is there a difference between http://192.168.c.d:8998/index.html and https://rogerthn.se/cumulusutils/

I use a different procedure than CumulusMX (which shows at http://192.168.c.d:8998/index.html ).
Different software.

What the exact differences are? I do not know, it has to do with the position of the sun you actually define as sunset/rise. Same for the moon but as that rotates faster and more complex differences may be larger.

It also may have to do with the time the calculation is made. CumulusMX calculates every hour (if I am well informed, @mcrossley no doubt can be more precise) and every calculation will produce a different estimate.
