I have very bad time awareness (as in very often don't remember what day or date it is). What I do is as soon as an event starts, I check the time, convert to my local time, and set up an event in calendar for the date 1 day before event end time. It would notify me that "Event X is ending in 1 day". Maybe you can try this method especially if multiple events are running at the same time?

Sorry to hear that. I was a bit alarmed with the overlap when the Road to 7 dropped and even though it follows the JP schedule, I agree it seemed like bad timing. Unless you've rolled for gacha CEs to clear the shop or if you've already rolled and completed the interludes that were half-off, then it's one or the other or apples.
