## Description
Manage your precious days at a glance!
D-Day is a simple yet powerful app that automatically calculates the D-Day for anniversaries, goal dates, and special occasions.
■ Key Features
▸ Automatic D-Day Calculation
Future dates are automatically displayed as D-23, the current day as D-Day, and past dates as D+500.
▸ Home Screen Widget
Check your upcoming D-Days directly on the home screen without opening the app.
The larger the widget, the more events are displayed, and items for the current day are highlighted separately.
▸ Accurate Push Notifications
Receive notifications at your desired date and time, ranging from the current day up to 180 days in advance.
You can set up to 10 notifications per D-Day.
Notifications turn on automatically upon new registration, ensuring you don't miss important dates.
▸ Lunar Calendar Support
Displays both Gregorian and Lunar dates simultaneously.
Lunar anniversaries (Lunar New Year, Chuseok, birthdays, etc.) are also automatically converted to the Gregorian calendar. ▸ Quick Date Selection
Since you select the year first and then the month, even birthdays from decades ago can be selected in just a few tries.
▸ Recurring D-Day
Set the date to recur weekly, monthly, annually (Solar), or annually (Lunar).
Once the date passes, it automatically moves to the next cycle, and the notification is rescheduled.
▸ Easy Re-registration
Quickly re-register past anniversaries for 1 week, 1 month, or 1 to 3 years later.
You can also set the date manually.
Re-registration is possible immediately on the actual D-Day.
▸ Share as Image
Create a beautiful card image of your D-Day and share it instantly on messengers or social media.
▸ Backup & Restore
You can export your D-Day as a file and restore it.
It can be transferred seamlessly even if you change phones, and you can revert to an automatic snapshot taken before restoration.
▸ Personalize with Emojis
Quickly find and use 293 types of emojis across 8 categories and via search.
Create an aesthetically pleasing D-Day list that is easily distinguishable at a glance. ▸ Dark Mode · Korean/English
Choose the theme and language that suits your preference.
▸ Sort Function
Sort by nearest or newest to quickly find your desired D-Day.
