Hi! Sorry for the confusion, the daily missions that are part of the Monthly event changes every week. What I recommend is to use the weeks that focus on certain things to make the best out of it. For example, some weeks would focus on Plot Instance, which I find a great way to make use of stacking and collecting awakening materials (never have enough of them). While the Elite Instance is great for Ninja Fragments, we all need more of those as well =P

I do realize that sometimes you might not have enough stamina, which is where the Hot Springs can come in! I myself find myself sometimes using stamina points because I really want those seal and summoning scrolls as redemption from the monthly event xD

Hope that helps, just pm me if there is anything I didn't explain very well =p
