How tu set hour, day and month in sunpath 1.20?

tutorial version have more input plugs

my 1.2.0 version
I can not find any instructions in this version. As beginner and a non-English speaker, I have encountered so many confusion about different between the version. Maybe the solution is very simple, tanks your answer!

Another question is why there is no sun display?

Hi Simon, please attach your script so we can see what you are doing / not doing.

Edit .

But for first question, use the LB analysis period component and connect it’s hoys output to the hoys input on your component.

Tanks your reply! I have learned a lot after this time of study.
