Used with 还有
快要 (kuài yào) is generally "about to" [happen], but 就要 (jiù yào) could be used to mark a more specific time. 要 (yào) here can be omitted. For this one, you wouldn't normally use "about to" for this English translation, but the feeling is nevertheless that the impending event is coming up fast.
