-- [] 주문 내역과 날짜를 비교해서, `혜택 내역`을 생산한다.
+- [x] 주문 내역과 날짜를 비교해서, `혜택 내역`을 생산한다.
     - [] 주문 내역에 날짜에 따른 할인 적용 여부를 적용해서, `할인 금액`을 계산한다.
     - [] 혜택 내역의 금액을 합쳐서, `총 혜택 금액`을 계산한다.
         - [] 주문 내역에 증정 이벤트가 포함되어 있을 시, 증정품의 가격까지 `총 혜택 금액`에 포함시킨다.

+## 추후 확장 및 코드 재사용 시 참고사항
+
+- `global/ApplicationConstant` 클래스의 <br>
+  `CURRENT_PROMOTION_MONTH`는 이벤트가 시행되는 월(month)을 의미합니다.
+  <br><br>
+- `ReservationDay` 클래스는 12월의 날짜 값과 12월 이벤트 도메인 로직을 처리하는 클래스입니다.<br>
+  해당 클래스는 `DayPerMonth`라는 추상 클래스를 상속받으며, 이 클래스는 유효 날짜 검증 로직을 가집니다.<br>
+  예를 들어, 다음 달 1월 이벤트를 위해 코드를 재사용 하신다면, 다음과 같은 순서로 진행하시면 됩니다.<br><br>
+    1. `domain.constant.reservationday.ReservationDayConstant` 클래스에서,<br>
+       `JANUARY_FIRST_DAY`, `JANUARY_LAST_DAY` 값을 추가합니다.<br><br>
+    2. `ReservationDay` 클래스의 `isInAppropriateRange`메서드의 DECEMBER 관련 상수 값을 1에서 생성한 상수 값으로 대체해줍니다.<br><br>
+    3. `ReservationDay` 클래스의 12월 관련 도메인 로직을 제거하고,<br> 1월 이벤트에 맞는 도메인 로직으로 클래스를 구성합니다.<br><br>
+    4. `EventManager` 클래스는 이벤트 관련 도메인 로직을 <br>예약 날짜와 주문 내역을 통해 해결하는 클래스입니다.<br><br>
+    5. `ReservationDay`클래스의 도메인 변경에 따른 `EventManager`도메인 로직을 수정해주시면 됩니다.이 때, `christmas.domain.constant.event` 폴더의
+       이벤트 변수 값을 변경 또는 활용해주시면 됩니다.

+### 1주일 뒤 개발 회의에서 논의하면 좋을 사항
+
+- 평일 할인 날에 아이스크림만 많이 시켜먹는 손님이 오면 매출에 불리할 것 같습니다.<br>
+  이에 대한 대응책이 필요하지 않을까요?<br><br>
+- 30일과 31일은 연말이라 손님이 많이 몰릴 시기인데, 이를 유인할만한 이벤트가 다소 부족한 것 같습니다.<br>
+  연말 이벤트를 추가하는 방안은 어떨까요?<br><br>
+- 증정 이벤트가 샴페인만 제공해주는 것 같아, 아이들과 함께 오는 부모님들에게는 그다지 유인책이 되지 않을 것 같습니다.
+  <br>고객을 유인하기 위해 샴페인을 제공하는 것인데, 오히려 아이들 앞에서 음주 장려(?)를 하는 것 같아 저희 식당을 이용하지 않을 수도 있을 거 같습니다.증정품을 다양화하는 것은 어떻게 생각하시나요?
