I already had a previous question, but that was pasted in vba tags etc. So I'll try again with proper tags and title since I gained a bit of knowledge now, hopefully.
The problem:
I need to find ~1000 dates from a database with plant variety data which probably is behind a login so here is a screenshot 
. Now I could of course fill out this form ~1000 times but there must be a smarter way to do this. If it were an HTML site I would know what to do, and have vba just pull in the results. I have been reading all morning about these javascript pages and ajax libraries but it is above my level. So hopefully someone can help me out a bit. I also used firebug to see what is going on when I press search:
These codes are similar to the last picture posted, make it easier to read. Code left here for copying.

And this is what it looks like in HTML, atleast according to firebug:

Edit:
It uses the GET method and XMLHttpRequest, as can be seen from this screenshot:
I already found how to make python run from excel vba here in this topic I also downloaded beautiful soup but python is not my kind of language, so any help would be greatly appreciated.
