🚀 Quick Start

1. Verify Tables:

# Check if tables were created
psql -d your_database -c "\dt holidays"
psql -d your_database -c "\dt admin_configurations"

2. Start the Backend:

npm run dev

You should see:

📅 Holiday calendar loaded for TAT calculations
[TAT Utils] Loaded 0 holidays into cache

3. Add Your First Holiday (via API):

As Admin user:

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"
  }'

4. Bulk Import Indian Holidays (Optional):

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

📊 How It Works

TAT Calculation with Holidays:

STANDARD Priority:

• ❌ Skips weekends (Saturday/Sunday)
• ❌ Skips holidays (from holidays table)
• ✅ Only counts working hours (9 AM - 6 PM)

EXPRESS Priority:

• ✅ Includes all days (24/7)
• ✅ No holidays or weekends excluded

🎯 Next Steps

For Backend Developers:

1. Test holiday API endpoints
2. Verify TAT calculations with holidays
3. Add more admin configurations as needed

For Frontend Developers:

1. Build Admin Holiday Management UI
2. Create Holiday Calendar view
3. Implement Configuration Settings page

🔍 Verify Setup

Check Holidays Table:

SELECT * FROM holidays;
-- Should return 0 rows (no holidays added yet)

Check Admin Configurations:

SELECT * FROM admin_configurations;
-- Should return 0 rows (will be seeded on first use)

Test Holiday API:

# Get all holidays for 2025
curl http://localhost:5000/api/admin/holidays?year=2025 \
  -H "Authorization: Bearer YOUR_ADMIN_TOKEN"

🎓 Example Usage

Create Request with Holiday in TAT Period:

// Create STANDARD priority request
POST /api/workflows
{
  "title": "Test Request",
  "priority": "STANDARD",
  "approvers": [
    { "email": "approver@example.com", "tatHours": 48 }
  ]
}

// If holidays exist between now and +48 hours:
// - Due date will be calculated skipping those holidays
// - TAT calculation will be accurate

🛠️ Troubleshooting

Holidays not excluded from TAT?

1. Check if holidays cache is loaded:
   • Look for "Loaded X holidays into cache" in server logs
2. Verify priority is STANDARD (EXPRESS doesn't use holidays)
3. Check if holiday exists and is active:

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

Cache not updating after adding holiday?

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