+# DatePicker 전체 교체 계획서
+
+> `input type="date"` → `DatePicker` 컴포넌트 교체
+> 작성일: 2026-02-06
+
+## 개요
+- 기존 브라우저 기본 `input type="date"`를 공통 `DatePicker` 컴포넌트로 교체
+- 공휴일/토요일/일요일 색상, 연월 직접 선택, 오늘 버튼 등 통일된 UX 제공
+
+## 교체 패턴
+```tsx
+// Before
+<Input type="date" value={value} onChange={(e) => setValue(e.target.value)} />
+
+// After
+import { DatePicker } from '@/components/ui/date-picker';
+<DatePicker value={value} onChange={setValue} />
+```
