If you're talking about sprint planning that sounds like you must have one month sprints and you should probably cut that down to something shorter. I've found 2 weeks to be the most effective. If you don't have one months sprints and still have a 8 hour meeting than your scrum master is not doing their job. Also, I would hope that you at least come out of the meeting with point values on all your stories for the next sprint and a defined sprint backlog. With each story having clear definable completion criteria and clear consensus around what the goal of the story is. If you are, that doesn't sound like a waste of time. If you aren't... back to your scrum master and their job. If you're talking about the actually daily scrum meeting... get out of there as fast as you can. I've seem meetings go a few minutes long but that is 7 hours and 45 minutes too long. We get upset when our meetings are longer than 8 minutes for a 10 person team.
