This service allows Czech University of Life Sciences Prague (CZU) students to automatically sync their university timetable with any calendar application that supports iCal/ICS subscriptions.

The service:

1. Logs into your CZU IS account
2. Retrieves your personal timetable
3. Converts it to iCal format
4. Serves it as a live calendar feed that you can subscribe to

Your calendar URL will be in the following format:

https://czu-ical.hajas.xyz/calendar/my.ical?login=YOUR_LOGIN&password=YOUR_PASSWORD

Replace YOUR_LOGIN with your CZU username and YOUR_PASSWORD with your CZU password.

⚠️ Security Note: Your credentials are sent as URL parameters. The calendar feed will be available to anyone who has access to this URL. Only use this service if you trust the hosting environment and ensure your calendar subscriptions are kept private.

Most calendar applications support iCal/ICS subscriptions. Look for options like:

• "Subscribe to calendar"
• "Add calendar from URL"
• "Import from web"
• "ICS subscription"

Then paste your calendar URL with your credentials.

The calendar subscription automatically syncs with your CZU timetable. The refresh frequency depends on your calendar app's settings (typically every few hours to once per day).

• Backend: Node.js with Express
• Language: TypeScript
• Authentication: Direct login to CZU IS
• Calendar Format: iCal/ICS

• Password Security: Your credentials are passed as URL parameters. Keep your calendar subscription links private.
• Changes: If you change your CZU password, you'll need to update the calendar URL in all your calendar apps.
• Support: This is an unofficial service and is not affiliated with or supported by CZU.
