It switches over after the event is over for *everyone*, so even though you have completed the event, there are some people who started the event a couple days late, so it doesn't end for them at the same time. I wish that we had a timer or something that told us when the event is completely over as I never remember from event to event. I think you can wait up to 2 days to start the event, so if it started on a Thursday at 11:00 PDT, the latest someone could start would be Saturday at 11:00 PDT, is that correct? And if it finished on Saturday at 6:00 PDT, then does that mean it was over for everyone on Monday at 6:00 PDT? Some clarification would be very helpful as this question (why haven't I started receiving the promised drops yet?) comes up Every. Single. Time.
