+## 13. 시즌별 마케팅 (Seasonal Marketing)
+
+### 13.1 핵심 방향
+
+세무사 사무실은 **1년 중 특정 시기에 특정 고객이 집중**된다. 홈페이지는 이 시기마다 자동으로 전환되어야 한다.
+
+**목표**: 방문자가 접속한 날짜에 맞는 세무 이벤트를 즉시 인지하고 상담 신청으로 전환
+
+**전환 방식**:
+- Hero 섹션 헤드라인과 CTA가 시즌에 맞게 변경됨
+- 마감 D-7일 이내에는 긴박감 메시지 추가 표시
+- 시즌 관련 서비스 카드가 맨 앞으로 이동
+- 최종 CTA도 시즌 문구로 전환
+- 관리자가 별도 공지사항을 등록하면 모든 페이지 최상단에 배너로 노출
+
+### 13.2 연간 세무 캘린더
+
+| 기간 | 이벤트 | Key | 타깃 서비스 |
+|------|--------|-----|-------------|
+| 1/1 ~ 1/25 | 부가가치세 2기 확정신고 | `vat-2nd` | business-tax |
+| 1/15 ~ 2/28 | 연말정산 | `year-end-settlement` | business-tax |
+| 3/1 ~ 3/31 | 법인세 신고 | `corporate-tax` | business-tax |
+| 5/1 ~ 5/31 | **종합소득세 신고** (연중 최대 피크) | `income-tax` | business-tax |
+| 7/1 ~ 7/25 | 부가가치세 1기 확정신고 | `vat-1st` | business-tax |
+| 11/15 ~ 11/30 | 종합부동산세 납부 | `comprehensive-real-estate-tax` | real-estate-tax |
+| 12/1 ~ 12/31 | 연말 증여·절세 플래닝 | `year-end-gift` | family-asset |
+
+캘린더 정의 위치: `TaxBaik.Application/Seasonal/TaxSeasonCalendar.cs`
+
+시즌 추가/수정은 이 파일만 변경하면 된다. DB·마이그레이션 변경 없음.
+
+### 13.3 공지사항 (Announcement)
+
+어드민 `/taxbaik/admin/announcements`에서 관리.
+
+- **유형**: 일반(info, 파란색) / 배너(banner, 주황색) / 긴급(urgent, 빨간색)
+- **게시 기간**: 시작일~종료일 설정 가능. 비우면 즉시~무기한
+- **노출 위치**: 홈페이지 최상단 (공지 배너 스트립)
+- **우선순위**: sort_order 내림차순
+
+공지사항은 시즌 Hero와 독립적으로 동작한다. 동시 표시 가능.
+
+### 13.4 시즌 우선순위 / 광고 규칙 준수
+
+- 허용: "지금 신고 준비하세요", "마감 전 사전 검토", "D-N일 남았습니다"
+- 금지: "100% 절세 보장", "최저가 신고", "무료"
+
