Easily check with the app when you need to calculate how much is left or how much has passed until D-Day, such as couples, weddings, anniversaries, baby births, diets, exams, and lunar birthdays.

If you set an anniversary, you will be notified at a glance through the notification bar at the top😄

■ Try using the anniversary D-day calculator app like this.

● D-day repetitive calculation function
- Calculate anniversaries that repeat every year, such as a couple's first year, wedding anniversary, birthday, lunar birthday, memorial service, etc.

(For anniversaries that repeat every year, if D-Day passes, the date is automatically calculated as next year's anniversary. In the case of the lunar calendar, the date is displayed by converting the lunar calendar to the solar calendar of the corresponding year.)

● Calculate remaining D-day
- Count the days remaining until important days such as D-100 days after birth
👍 If the anniversary is just a few days away or is on the day of D-Day, click on the D-Day list and share it with your friends.

● Calculate past days
: Calculate past dates, such as marriage D+1000 days, diet +30 days, etc.
👍When calculating the period past an anniversary, such as 365 days of love or 100 days of a baby, please use the function that calculates +1 day from the anniversary.

■ We provide the following functions to calculate and manage anniversaries.

● Top bar & lock screen D-day provided
- We will also inform you of D-Day on the top bar and lock screen so that you do not miss the anniversary you have set.

● Share anniversary & D-day schedule
- You can share the days remaining until your anniversary with your acquaintances or spouse.

■ These features will be added in the future.

● D-day sequence management function
- We plan to provide an order editing function so that you can check important anniversaries first.

● Ability to decorate cover photos for each D-day to make it easier to remember.
Register a baby ultrasound photo as a cover photo when counting the D-day for childbirth, a cover photo showing students studying hard for the CSAT count, and a happy photo of just the two of you as a cover photo when counting the D-day of a couple's anniversary.

● D-Day widget
We will send you a notification in advance so that you do not forget or expose it to the registered D-Day widget.
* Widgets or notifications are optional, and notifications are provided before the date approaches, such as 1 day before the D-day.
