Problem:
It can be a little confusing knowing when an event will end (how long we have to recruit event girls). The difference in time zones mean that the date can be different from what's given in the announcement (the date may be the 25th in the announcement, but that means the 24th for most of the United States).
Solution:
Similar to the timers for harem income, activities, and arena, create an event timer on the homepage / town screen. A good spot for this timer might be at the top right beneath the navigation button.
Additionally, it'd be nice to have timers for when the market is refreshing, our next booster is expiring, the weekly tower of fame competitions end, and the next free spin for Pachinko.
Edit: And, using the same timer to show when the next event will BEGIN, would also be much appreciated.
