The supplied source description says the Petit Planet Final Beta began on September 20. It does not specify the year or when the test ends.
The source describes the beta period as having an undetermined duration. Because it provides no end date, use September 20 only as the reported start date; the supplied material cannot confirm whether the beta is still running.
