Falcon day today....

As noted, time applied to the event only counts from July 1st onward. Your current sub made you ineligible for September since it'd put you at only 60 days (July through to August). You'll receive the mount next month as September will be applied, bringing the total to 90 days.

Pixie. I think you missed the part of me being subbed for a year. Or translation. This account has been here since LAST Yokai event.

Like Dusty said. You need to have reached 90 days between the two designated windows. The event ignores any prior sub time. Say you subbed for three months in June. It would only counts July through to August, making you ineligible for the September giveaway. When you renew that sub, it'll include September, thus making you eligible for the October giveaway.
