Implement calendar display application

Built a full-featured smart display app with Flask backend and responsive frontend. Features: - Real-time clock display - Weather integration (OpenWeatherMap API) for Hamilton, NZ - Google Calendar integration (placeholder, needs credentials) - Rotating background images from local directory - Dad jokes display (icanhazdadjoke API) Technical stack: - Backend: Python Flask with API endpoints - Frontend: HTML/CSS/JavaScript with auto-updating data - Caching system to avoid API rate limits - Responsive design for various screen sizes Deployment ready for Raspberry Pi with systemd service and Chromium kiosk mode setup instructions.

-# Calender
+# Family Calendar Display

-Project created: February 14, 2026
+A smart display application for Raspberry Pi that shows time, weather, calendar events, and rotating background images.
+
+**Project created:** February 14, 2026
+
+## Features
+
+- 🕐 **Real-time Clock** - Current time and date display
+- 🌤️ **Weather** - Current weather and 5-day forecast for Hamilton, New Zealand (OpenWeatherMap)
+- 📅 **Google Calendar** - Family calendar events display
+- 🖼️ **Rotating Backgrounds** - Beautiful images from local directory
+- 😄 **Dad Jokes** - Random jokes to brighten your day (optional)
+
+## Requirements
+
+- Python 3.8+
+- Raspberry Pi (tested on Pi 3/4) or any Linux system
+- Google Calendar API credentials
+- OpenWeatherMap API key (free tier)
+
+## Quick Start
+
+### 1. Clone the Repository
+
+```bash
+git clone ssh://git@gitea.meyfamily.co.nz:2222/luddie/Calender.git
+cd Calender
+```
+
+### 2. Install Dependencies
+
+```bash
+python3 -m venv venv
+source venv/bin/activate  # On Windows: venv\Scripts\activate
+pip install -r requirements.txt
+```
+
+### 3. Configure Environment Variables
+
+```bash
+cp .env.example .env
+```
+
+Edit [.env](.env) and add your API keys:
+
+```bash
+# Get your OpenWeatherMap API key from: https://openweathermap.org/api
+OPENWEATHER_API_KEY=your_api_key_here
+
+# Your Google Calendar ID (found in Google Calendar settings)
+GOOGLE_CALENDAR_ID=your_calendar_id@group.calendar.google.com
+
+# Generate a secret key for Flask
+FLASK_SECRET_KEY=your_random_secret_key
+```
+
+### 4. Set Up Google Calendar API
+
+1. Go to [Google Cloud Console](https://console.cloud.google.com/)
+2. Create a new project or select existing one
+3. Enable the Google Calendar API
+4. Create credentials (OAuth 2.0 or Service Account)
+5. Download the credentials JSON file
+6. Save it as [credentials/google_calendar_credentials.json](credentials/google_calendar_credentials.json)
+
+### 5. Add Background Images
+
+Place your images in the [static/backgrounds/](static/backgrounds/) directory:
+
+```bash
+cp /path/to/your/images/*.jpg static/backgrounds/
+```
+
+Supported formats: JPG, PNG, GIF, WebP
+
+### 6. Run the Application
+
+```bash
+python app.py
+```
+
+Visit `http://localhost:5000` in your browser.
+
+## Raspberry Pi Deployment
+
+### Auto-start Flask Application
+
+Create a systemd service:
+
+```bash
+sudo nano /etc/systemd/system/calendar-display.service
+```
+
+Add the following content:
+
+```ini
+[Unit]
+Description=Calendar Display Flask App
+After=network.target
+
+[Service]
+User=pi
+WorkingDirectory=/home/pi/Calender
+ExecStart=/home/pi/Calender/venv/bin/python app.py
+Restart=always
+Environment="PATH=/home/pi/Calender/venv/bin"
+
+[Install]
+WantedBy=multi-user.target
+```
+
+Enable and start the service:
+
+```bash
+sudo systemctl daemon-reload
+sudo systemctl enable calendar-display.service
+sudo systemctl start calendar-display.service
+```
+
+### Configure Chromium Kiosk Mode
+
+Edit the autostart file:
+
+```bash
+mkdir -p ~/.config/lxsession/LXDE-pi
+nano ~/.config/lxsession/LXDE-pi/autostart
+```
+
+Add these lines:
+
+```bash
+@xset s off
+@xset -dpms
+@xset s noblank
+@chromium-browser --kiosk --noerrdialogs --disable-infobars --disable-session-crashed-bubble http://localhost:5000
+```
+
+Disable screensaver and cursor (optional):
+
+```bash
+sudo apt-get install unclutter
+echo "@unclutter -idle 0" >> ~/.config/lxsession/LXDE-pi/autostart
+```
+
+### Reboot
+
+```bash
+sudo reboot
+```
+
+The display should now start automatically on boot!
+
+## Configuration
+
+Edit [.env](.env) to customize:
+
+- `IMAGE_ROTATION_INTERVAL` - Seconds between background changes (default: 300)
+- `WEATHER_UPDATE_INTERVAL` - Seconds between weather updates (default: 900)
+- `CALENDAR_UPDATE_INTERVAL` - Seconds between calendar updates (default: 300)
+- `JOKE_UPDATE_INTERVAL` - Seconds between joke updates (default: 3600)
+- `CALENDAR_DAYS_AHEAD` - Number of days ahead to show events (default: 7)
+

+```
+
+## API Endpoints
+
+- `GET /` - Main display page
+- `GET /api/weather` - Weather data (cached for 15 min)
+- `GET /api/calendar` - Calendar events (cached for 5 min)
+- `GET /api/background` - Random background image
+- `GET /api/joke` - Dad joke (cached for 1 hour)
+
+## Troubleshooting
+
+### Weather not loading
+- Check your OpenWeatherMap API key is valid
+- Ensure you're not exceeding the free tier rate limits (60 calls/min)
+
+### Calendar not loading
+- Verify Google Calendar API credentials are set up correctly
+- Check the calendar ID is correct
+- Ensure the service account has access to the calendar
+
+### Display not starting on boot
+- Check systemd service status: `sudo systemctl status calendar-display.service`
+- View logs: `sudo journalctl -u calendar-display.service -f`
+
+### Background images not showing
+- Ensure images are in [static/backgrounds/](static/backgrounds/)
+- Check file permissions: `chmod 644 static/backgrounds/*`
