## What is D?

Count the days since and until your special dates in one big number. See what weekday your next milestone falls on, and keep a day on your Lock Screen widget. The interface follows your system language in Korean or English.

• Choose from six kinds of dates: relationship, baby, birthday, wedding, upcoming, or custom.
• Choose whether the first day counts as day one. Existing counting settings stay the same until you change them.
• See milestones suited to each kind, including 100 days, months, anniversaries, birthdays, and past milestones.
• Search all days, filter by kind, pin a date, drag your personal order, and preview the next 30 days.
• Repeat Korean lunar birthdays using offline solar-date conversion for 1900–2050, with a choice of leap-month rules.
• Use small and medium home screen widgets and lock screen widgets. Choose a different day for each widget (iOS 17 or later).
• Set reminders in your local time. Choose date and milestone reminders and their hour. The nearest 60 reminders are refilled when you open the app.
• Celebrate milestones and share square or portrait image cards. Hide the name before sharing; notes are always excluded.
• Calculate the days between dates or a date N days away, then add the result directly.
• Export and restore JSON backups, use dark mode, and follow your system language in Korean or English.

No ads, tracking, or account. Your dates stay on your device. Fonts and Korean lunar data are bundled with the app.

What's New:
A new large-number home and next-day preview, with milestones by kind, Korean lunar recurrence, widget day selection, image cards, and a date calculator. Ads and tracking have been removed while existing dates, backups, and counting settings are preserved. The app icon has also been refreshed.
