D-Day: Countdown & Widget

About D-Day: Countdown & Widget

How many days until the day that matters? D-Day is a simple countdown counter for exams,
birthdays, anniversaries, and every big date. Count down the days that are coming, count up
the days since something started, and let yearly dates renew themselves automatically.

What you can do
• Countdown — see the days left until any date, like D-30 or D-1
• Days since (count-up) — track how long since you started, met, or quit
• Yearly repeat — birthdays and anniversaries roll over to this year on their own
• Quick add — one-tap templates for Exam, Discharge, Birthday, Anniversary, and Wedding
• Home-screen widget — pin a D-day (or show the nearest one) right on your home screen
• Share — send a D-day to a friend in a tap
• Light & dark themes, plus in-app language switch (English, Korean, Japanese, Chinese)
• No sign-up, works fully offline

Great for
• Students counting down to an exam or test
• Anyone waiting on a big date — a trip, a due date, a move
• Couples tracking anniversaries like 100 days or the first year
• Never missing a birthday or wedding anniversary again
