Day Count is a focused countdown and count-up tool for birthdays, anniversaries, trips, exams, payments, holidays, and personal milestones.
Enter an event and target date to see a compact summary with days remaining or elapsed, full weeks, extra days, the effective target date, and its weekday. Quick presets for Anniversary, Birthday, Trip, Exam, and Payment fill in the name, category, and repeat choice with one tap. Annual events automatically advance to their next occurrence, including safe handling for leap-day dates.
Save complete scenarios—including the event name, date, category, reminder timing, annual repeat, pin state, and notes. Tap Load at any time to restore the full form and recalculate the result instantly.
Choose an optional reminder for the event day, or 1, 7, or 30 days beforehand; notifications arrive at 9 AM local time. Saved reminders are restored after restarts and time or timezone changes. Pin important scenarios, add notes for context, and switch between light, dark, or system theme. The interface is available in English, Simplified Chinese, and Traditional Chinese, with a two-column layout on tablets. Scenario data is stored locally on your device.
