For how long is registration open for recurring meetings?

Hi,

I created a recurring meeting with following dates:

- October 17,

- October 24

- November 7

- November 14

As for reucurring meetings you can not untick "Close registration after the meeting date.", for how long people can register for one of these events? I want to make sure people can register on November 12 for the event on November 14.

Thanks!
