How it works
The countdown uses today’s date in your device’s time zone. Future dates show D−N, past dates show D+N, and today shows D-Day. This is a calendar-day countdown, not a timer measured in hours.
How to use
- Choose the date of your event.
- Check the displayed local date.
- Read the days remaining or elapsed.
