Valarie Brown is feeling Confused

I need help understanding feast days and appointed times, especially when to observe. I have come across teachings where the moon is used to calculate and another where the moon and the sun is used to calculate. The only feast my family and myself has kept so far is the Passover and even with that I found that a couple assemblies, I follow through YouTube, had observe Passover a week prior and others were observing a week later. It's a bit confusing.
Family, does anyone have any suggestions where newbies can go and be taught at the foundation level?
