Overview
Form Calendar™ — automatically open and close Google Forms™ based on your Google Calendar™ events.

📅 Calendar-Based Scheduling
Connect any Google Calendar™ to control when your form accepts responses. Events on the calendar = form open. No events = form closed. Supports recurring events — create a weekly calendar event and your form opens and closes every week automatically.

⏰ Automatic Open & Close
Form Calendar™ reads your calendar events and creates triggers that open the form when an event starts and close it when it ends. Works even when you're offline. Events less than 1 hour apart are merged into continuous windows.

🔢 Per-Event Response Limits
Set a maximum number of responses per event window. The form closes early if the limit is reached before the event ends — perfect for capping registrations per session.

📧 Email Notifications
Receive instant email alerts when your form automatically opens or closes. Stay informed without checking manually.

📱 QR Code Generator & Sharing
Generate QR codes for easy form sharing. Download as PNG or share directly via WhatsApp, SMS, Email, X, LinkedIn, or Telegram.
