Time off during first 6 months?

I'm currently waiting for the call to start the apprenticeship. I have 3 weddings for some of my closest friends in the next 4-5 months that would be unfortunate if I missed.

Let's say I get called up before these events. Should I expect to just miss them or do you think the hall will show some leniency since they were prior engagements?

At the end of the day, I'm going to prioritize the apprenticeship and miss the weddings if needed.

I'll call the hall after the holidays and get their feedback too, but was curious if anyone else had this situation early on in their apprenticeship.
