A reminder fired ahead of an event on a different day showed only the event's time (e.g. "09:30 – 10:00"), making it look like it was happening today. reminderTimeText now prefixes timed events with a relative day: "Tomorrow"/"Yesterday", the short weekday for another day this week, or the exact date for anything further out. The this-week boundary honours the user's "week starts on" setting: the resolved first day of week is threaded through from ReminderNotifier, so e.g. a Sunday reads as next week under a Sunday-start locale. All-day events keep their explicit date (never ambiguous), and cross-midnight timed events keep both explicit dates. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
