Something that annoys me about Harry Potter
It would have taken JK like 1 minute to check dates for continuity. GoF is set in 1994, and the Goblet of Fire drew names on 31st October 1994, which was a Monday. But Harry "woke up on Sunday" and "remembered the events on the night before" the day after it drew his name. I am sure there are other instances of this throughout the series, but I noticed it listening the the audiobooks again.
