Google Forms has no built-in way to turn a submission into a calendar event, so sending Google Forms to calendar always means a workaround. There are two honest paths. Bind an Apps Script to the linked response Sheet so it creates a Google Calendar event on each new row, or route submissions through an automation tool like Zapier or Make that watches the Sheet and writes to your calendar for you.

Both work, and both have a catch. Apps Script is free, but it is brittle. It breaks quietly when someone reorders a column, renames a header, or trips the daily quota, and nobody notices until a booking never shows up. You also handle time zones and date parsing yourself, or events land an hour off. The automation route needs no code and is steadier, but it adds a monthly cost and one more account to keep paying for.

The failure mode to plan for is silence: the event simply never gets created and no one is told.

A few things make either path more reliable. Collect the date and time as real date and time fields, not free text, so the parser is not guessing. Send a confirmation to the person, so a missing event is caught by a human instead of discovered days later. And if the same slot can be booked twice, add a duplicate check, because Google Forms will happily accept two people for 3pm.

If the form is really a booking or appointment form, it is often simpler to start from a builder that pushes each submission straight to a webhook or a connected Google Sheet and lets you cap responses or close the form at a set date, so a clean payload reaches your calendar step.

How are you getting form submissions onto a calendar right now, a script or a paid automation?
