Narrative:
During the navigation preflight, I noted that the navigation data was out of date by one day. I brought this to the attention of the captain. He contacted maintenance and they instructed us to fly the aircraft to bwi. Upon arrival at bwi, maintenance updated the navigation data to the current date. All of our navigating was backed up using the raw data from the VOR navaids. The approach and landing were uneventful.
