+## Date Field Display Format (Discovered during 07-01 testing)
+
+**Issue:** The deadline date field displays in raw YYYYMMDD format instead of a user-friendly German format
+
+**Current Behavior:**
+- Date field on job edit form displays as "20260130" (raw format)
+- Not user-friendly, difficult to read at a glance
+- Inconsistent with German date conventions
+
+**Expected Behavior:**
+- Date should display in German format: "30.01.2026" (DD.MM.YYYY)
+- Both in the date input field and when pre-populated
+- Should be consistent across all forms (submission, edit, deactivation)
+
+**Location:**
+- Provider Dashboard edit form (`/anbieter-dashboard/?action=edit_job&job_id=XXX`)
+- Specifically the "Bewerbungsfrist" (deadline) field
+
+**Impact:** Low - Cosmetic issue, doesn't affect functionality
+**Priority:** Low
+**Phase Discovered:** 07-01 (Provider flow testing)
+
+**Fix Required:**
+1. Check Formidable form date field settings for proper format
+2. Ensure date format is set to German locale (DD.MM.YYYY)
+3. Update form field configuration or add custom formatting
+4. Test date display on both submission and edit forms
