A Google Calendar™ add-on for holding several candidate dates at once.

Install from the Google Workspace Marketplace

In the calendar side panel, a plan is given a title and a time, three candidate dates are picked, and three gray holds appear on the calendar. Confirming one of them removes the other two and leaves the confirmed date as a normal event. — Three candidate dates are held in one step; confirming the one that works clears the rest.

What it does

Block out several candidate dates for one plan, in a single step
Holds are created in gray and prefixed with [Hold], so they stand out
Once the date is decided, keep the one you confirm as a normal event and delete the rest
Add or remove candidates, edit their content, and clean up holds that fell through

How it is built

All state lives inside your own calendar — there is no external database
Only the permissions needed to read and write your own events are requested
Anything that deletes events shows you the list first, and waits for your confirmation
