Hi Ed,
I ran into a similar problem a while back, so far my astronomy page has been correct, I think, lol.
https://www.pennlake.us/wxastronomy.phpIf you are using WD this is what I figured out a while back -- Perhaps it can help you, I think I just got lucky that day.
It went something like this - WD was using jpeg's and the wx script was using gif's.
Oh so here I found a copy of the post -- hope it helps.
In the wxastronomy.php script, in the Sun and Moon Almanac, if you have not modified the script there are 2 big boxes outlined at the bottom of the page.
The top box has the Julian date - UTC time .... and the bottom shows some seasonal events.
Anyway, the dates in mine have been reading from 2016, so the sunrise -set time and all that was always off and stagnant. So for 2 years or so I have been looking at this and thinking this is not right.
So what I found out last night, was that the script is set to read .gif's and in my case I believe WD is uploading revised .jpg's files and the gif's where never being updated so the wxastronomy.php script was looking and showing the non-updated gif's.
So I went into the wxastronomy script and changed every thing to read .jpg's and all seems to be working, at least for me.
