The Community Round will close for sure at the company's offering deadline. 

However, a successful Community Round almost always closes earlier (although it must be open for at least 21 days).  Additionally, some companies may do a "rolling close" after 21 days have passed and their minimum fundraising target is reached.

When a Community Round closes earlier, you will receive a five-day notice before the closing date via email, and a 7-day countdown will be visible on the Community Round page.
