# Day-Specific Booking Times & User Display Features

## Overview

This update introduces two major features to the table tennis booking system:

### 1. Day-Specific Booking Times

The system now supports different booking hours for different days of the week. Administrators can configure custom time slots for each day (Sunday through Saturday).

#### Example Configuration:

-   **Sunday**: 12:00 - 17:00 (Weekend afternoon sessions)
-   **Monday**: 19:00 - 23:00 (Evening sessions only)
-   **Tuesday**: 19:00 - 23:00 (Evening sessions only)
-   **Wednesday**: 18:00 - 22:00 (Shorter evening sessions)
-   **Thursday**: 19:00 - 23:00 (Evening sessions only)
-   **Friday**: 18:00 - 22:00 (Shorter evening sessions)
-   **Saturday**: 10:00 - 18:00 (Full day weekend sessions)

### 2. User Name Display

The booking calendar now shows who has booked each court slot, displaying the full name of the person who made the booking.

## Implementation Details

### Database Schema

The system uses the existing `timeSlots` table in the database schema:

```sql
CREATE TABLE time_slots (
    id TEXT PRIMARY KEY,
    dayOfWeek INTEGER NOT NULL,  -- 0 = Sunday, 1 = Monday, etc.
    startTime TEXT NOT NULL,     -- Format: "HH:MM"
    endTime TEXT NOT NULL,       -- Format: "HH:MM"
    isActive BOOLEAN DEFAULT TRUE,
    createdAt INTEGER NOT NULL,
    updatedAt INTEGER NOT NULL
);
```

### API Endpoints

#### Public Endpoints (for authenticated users):

-   `GET /api/time-slots` - Retrieve active time slots for all days
-   `GET /api/bookings/all?date=YYYY-MM-DD` - Get all bookings with user and court information

#### Admin Endpoints:

-   `GET /api/admin/time-slots` - Retrieve all time slots (including inactive)
-   `POST /api/admin/time-slots` - Create new time slot
-   `PUT /api/admin/time-slots/[id]` - Update existing time slot
-   `DELETE /api/admin/time-slots/[id]` - Delete time slot

### Admin Management

Administrators can manage time slots through the admin dashboard under the "Settings" tab. The interface allows:

-   **Create Time Slots**: Set day of week, start time, end time, and active status
-   **Edit Time Slots**: Modify existing time slot configurations
-   **Delete Time Slots**: Remove time slot configurations
-   **Activate/Deactivate**: Toggle time slots on/off without deletion

### User Experience

#### Enhanced Booking Calendar:

-   Automatically adapts to show only available time slots for the selected day
-   Displays who has booked each unavailable slot
-   Maintains mobile-responsive design
-   Provides fallback to global settings if no day-specific slots are configured

#### Booking Display:

-   Available slots: Green background with "Book" button
-   Booked slots: Red background showing "Booked by [Full Name]"
-   Clear visual distinction between available and booked slots

## Usage Instructions

### For Administrators:

1. **Navigate to Admin Dashboard** → Settings tab
2. **Time Slot Management section** allows you to:
    - Add new time slots for specific days
    - Edit existing time slot configurations
    - View all time slots organized by day of the week
    - Activate/deactivate time slots as needed

### For Users:

1. **Select a date** in the enhanced booking calendar
2. **View available time slots** automatically filtered for that day
