Are the URL's for moderated meetings at permanent?

My club meets monthly, more or less. In January we started using Each time, I have booked a moderated meeting in advance, and then emailed the moderator URL to the club officers & the general URL to the other club members, along with a meeting date & time. I have never set up any password.

My questions:

How far in advance can I book a meeting URL? Will it expire if we wait too long to use it?

Once we do hold our meeting & use the URL, does it expire? Or could we keep using the same URL’s (moderator & participant) for future meetings?

Thanks for any advice on this!

The links are randomly generated and unique, so the chances of someone else getting your link are extremely low. They don’t expire, so you’re able to reuse the same link without problems.

Thank you.
