Will my order take the whole weekend to process?

I just ordered the iPhone XS and I'm really excited to get it in, but I ordered it late Friday night and I chose Express delivery so I could get the phone and case on the same day, since the case was gonna come a day later and I'm stupidly clumsy. So, I was really curious, I know Apple doesn't ship on weekends, but will it process my order over the weekend? After a quick Google Search the only thing I was able to find on this topic was that Apple starts processing orders 45 minutes after they receive them... so will my order be processed so I can get my new phone on time?
