Launch periods and launch windows are not the same thing. From my understanding from what I have read Virgin Galactic has a launch period from Dec 9 through Dec 20th with multiple launch Windows.

"In the context of spaceflight, launch period is the collection of days and launch window is the time period on a given day during which a particular rocket must be launched in order to reach its intended target.[1][2] If the rocket is not launched within a given window, it has to wait for the window on the next day of the period.[3] Launch periods and launch windows are very dependent on both the rocket's capability and the orbit to which it is going.[4][5]"

So I believe they have until the 20th of this month to utilize.

We look forward to sharing information on our next flight window in the near future," Colglazier added in another tweet.
