Navblue has added red dates to the PBS Calendar. These dates have no effect on bidding and only represent the "blackout dates" for a very small subset of pilots who wish to slide PVAC regardless of coverage up to three days in accordance with PWA 7.E.7.b Exception. Navblue was asked to remove the red dates from the PBS Calendar back in July. You can ignore the red dates you see in November, December, and January.
