According to the courseware page:
You are welcome to take CS50x at your own pace, per the Schedule, starting whenever you'd like, so long as you finish before 31 December 2014. (For those who finish before then, certificates will also be generated in June 2014 and September 2014.) So no worries if this is your first time here!
From my experience last year, when the deadline was 15 April 2013, the certificates were issued within a couple of weeks. It will be shown on your edX dashboard when it is ready for download.

We have the 31 December deadline to finish all the projects, but when exactly will everyone recieve the certificates (verified or honor code)?
