Pastaria's release date preview was 4 days before the preview.
So if you are correct, then the release date would be 4 days after its preview, which would be the 15th, a Sunday.
However, it would more likely be a Monday or a Friday, so the preview will actually be a Thursday.
In this case, it would be the 16th, a Monday.
So Taylor99 is incorrect, but he had a good guess.
