✅ Supports recurring holidays (annual)
✅ Department/location-specific holidays
✅ Bulk import from JSON/CSV
✅ Year-based calendar view
✅ Automatic cache refresh

2. Admin Configuration System ⚙️

✅ Centralized configuration management
✅ All planned config areas supported:
- TAT Settings
- User Roles
- Notification Rules
- Document Policy
- Dashboard Layout
- AI Configuration
- Workflow Sharing Policy

📊 Database Schema

New Tables Created:

1. holidays Table:

- holiday_id (UUID, PK)
- holiday_date (DATE, UNIQUE) -- YYYY-MM-DD
- holiday_name (VARCHAR) -- "Diwali", "Republic Day"
- description (TEXT) -- Optional details
- is_recurring (BOOLEAN) -- Annual holidays
- recurrence_rule (VARCHAR) -- RRULE format
- holiday_type (ENUM) -- NATIONAL, REGIONAL, ORGANIZATIONAL, OPTIONAL
- is_active (BOOLEAN) -- Enable/disable
- applies_to_departments (TEXT[]) -- NULL = all
- applies_to_locations (TEXT[]) -- NULL = all
- created_by (UUID FK)
- updated_by (UUID FK)
- created_at, updated_at

2. admin_configurations Table:

- config_id (UUID, PK)
- config_key (VARCHAR, UNIQUE) -- "DEFAULT_TAT_EXPRESS_HOURS"
- config_category (ENUM) -- TAT_SETTINGS, NOTIFICATION_RULES, etc.
- config_value (TEXT) -- Actual value

🎯 TAT Calculation with Holidays

STANDARD Priority (Working Days):

Excludes:

✅ Saturdays (day 6)
✅ Sundays (day 0)
✅ Holidays from holidays table
✅ Outside working hours (before 9 AM, after 6 PM)

Example:

Submit: Monday Oct 20 at 10:00 AM
TAT: 48 hours (STANDARD priority)
Holiday: Tuesday Oct 21 (Diwali)

Calculation:
Monday 10 AM - 6 PM = 8 hours (total: 8h)
Tuesday = HOLIDAY (skipped)
Wednesday 9 AM - 6 PM = 9 hours (total: 17h)
Thursday 9 AM - 6 PM = 9 hours (total: 26h)
Friday 9 AM - 6 PM = 9 hours (total: 35h)
Saturday-Sunday = WEEKEND (skipped)
Monday 9 AM - 10 PM = 13 hours (total: 48h)

Due: Monday Oct 27 at 10:00 AM

EXPRESS Priority (Calendar Days):

Excludes: NOTHING

All days included (weekends, holidays, 24/7)

Example:

Submit: Monday Oct 20 at 10:00 AM
TAT: 48 hours (EXPRESS priority)

Due: Wednesday Oct 22 at 10:00 AM (exactly 48 hours later)

🔄 Holiday Cache System

How It Works:

1. Server Starts
   ↓
2. Load holidays from database (current year + next year)
   ↓
3. Store in memory cache (Set of date strings)
   ↓
4. Cache expires after 6 hours
   ↓
5. Auto-reload when expired
   ↓
6. Manual reload when admin adds/updates/deletes holiday

Benefits:

⚡ Fast lookups (O(1) Set lookup)
💾 Minimal memory (just date strings)
🔄 Auto-refresh every 6 hours
🎯 Immediate update when admin changes holidays

🎨 Frontend UI (To Be Built)

Admin Dashboard → Holiday Management:

<HolidayManagementPage>
  {/* Year Selector */}
  <YearSelector 
    currentYear={2025}
    onChange={loadHolidaysForYear}
  />
  
  {/* Calendar View */}
  <CalendarGrid year={2025}>
    {/* Days with holidays highlighted */}
    <Day date="2025-01-26" isHoliday holidayName="Republic Day" />
    <Day date="2025-08-15" isHoliday holidayName="Independence Day" />
  </CalendarGrid>
  
  {/* List View */}
  <HolidayList>
    <HolidayCard
      date="2025-01-26"
      name="Republic Day"
      type="NATIONAL"
      recurring={true}
      onEdit={handleEdit}
      onDelete={handleDelete}
    />
  </HolidayList>
  
  {/* Actions */}
  <div className="actions">
    <Button onClick={openAddHolidayModal}>
      + Add Holiday
    </Button>
    <Button onClick={openBulkImportDialog}>
      📁 Import Holidays
    </Button>
  </div>
</HolidayManagementPage>

🚀 Quick Start

Step 1: Run Migrations

cd Re_Backend
npm run migrate

You'll see:

✅ Holidays table created successfully
✅ Admin configurations table created and seeded

Step 2: Import Indian Holidays (Optional)

Create a script or use the API:

# Using curl (requires admin token):
curl -X POST http://localhost:5000/api/admin/holidays/bulk-import \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_ADMIN_TOKEN" \
  -d @data/indian_holidays_2025.json

Step 3: Verify Holidays Loaded

SELECT COUNT(*) FROM holidays WHERE is_active = true;
-- Should return 14 (or however many you imported)

Step 4: Restart Backend

npm run dev

You'll see:

📅 Holiday calendar loaded for TAT calculations
Loaded 14 holidays into cache

🧪 Testing

Test 1: Create Holiday

POST /api/admin/holidays
{
  "holidayDate": "2025-12-31",
  "holidayName": "New Year's Eve",
  "description": "Last day of the year",
  "holidayType": "ORGANIZATIONAL"
}

Test 2: Verify Holiday Affects TAT

# 1. Create STANDARD priority request on Dec 30
# 2. Set TAT: 16 hours (2 working days)
# 3. Expected due: Jan 2 (skips Dec 31 holiday + weekend)
# 4. Actual due should be: Jan 2

Test 3: Verify EXPRESS Not Affected

# 1. Create EXPRESS priority request on Dec 30
# 2. Set TAT: 48 hours
# 3. Expected due: Jan 1 (exactly 48 hours, includes holiday)

curl -X POST http://localhost:5000/api/admin/holidays \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_ADMIN_TOKEN" \
  -d '{
    "holidayDate": "2025-11-05",
    "holidayName": "Diwali",
    "description": "Festival of Lights",
    "holidayType": "NATIONAL"
  }'

  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_ADMIN_TOKEN" \
  -d @data/indian_holidays_2025.json

Step 4: Test TAT with Holidays

# 1. Create STANDARD priority request
# 2. TAT calculation will now skip holidays
# 3. Due date will be later if holidays fall within TAT period

📊 TAT Calculation Examples

Example 1: No Holidays in TAT Period

Submit: Monday Dec 1, 10:00 AM
TAT: 24 hours (STANDARD)
Holidays: None in this period

Calculation:
Monday 10 AM - 6 PM = 8 hours
Tuesday 9 AM - 1 PM = 4 hours
Total = 12 hours (needs 12 more)
...
Due: Tuesday 1:00 PM

Example 2: Holiday in TAT Period

Submit: Friday Oct 31, 10:00 AM
TAT: 24 hours (STANDARD)
Holiday: Monday Nov 3 (Diwali)

Calculation:
Friday 10 AM - 6 PM = 8 hours
Saturday-Sunday = WEEKEND (skipped)
Monday = HOLIDAY (skipped)
Tuesday 9 AM - 6 PM = 9 hours (total: 17h)
Wednesday 9 AM - 2 PM = 5 hours (total: 22h)
...
Due: Wednesday Nov 5 at 2:00 PM

🔒 Security

📊 Impact on Existing Requests

For Existing Requests:

Before Holidays Table:

TAT calculation: Weekends only

After Holidays Table:

TAT calculation: Weekends + Holidays
Due dates may change for active requests
Historical requests unchanged

🆘 Troubleshooting

Holidays Not Excluded from TAT?

Check:

Holidays cache loaded? Look for "Loaded X holidays into cache" in logs
Priority is STANDARD? (EXPRESS doesn't use holidays)
Holiday is active? is_active = true
Holiday date is correct format? YYYY-MM-DD

Debug:

-- Check if holiday exists
SELECT * FROM holidays 
WHERE holiday_date = '2025-11-05'
  AND is_active = true;

Cache Not Updating After Adding Holiday?

Solution:

Cache refreshes automatically when admin adds/updates/deletes
If not working, restart backend server
Cache refreshes every 6 hours automatically

📈 Future Admin Features

Based on your requirements, these can be added:

User Role Management:

Add/remove users
Change user roles
Activate/deactivate accounts

Notification Templates:
