Where can I go to keep track in advance of key events that affect the stock market?

I'm relatively new to stocks but it's been a huge mess for me lately losing tons of money due to events like Powell's announcement on more hikes and now the recent government shutdown.

I had absolutely ZERO idea any of these events were happening until I read it on the news hours afrer it occured.

So I'd like to plan in advance next time to get ready for such things. How do I do that though? Where do you guys go to get a heads-up timeline of such events and when they will happen?? Events like Fed announcements, key government decisions, company earnings calls etc..?

Is there some website that will summarize when these events will happen?
