Air Combat Command overcame the first Y2K hurdle April 9 when the Julian day 99 came and went without a hitch. Unit Readiness chief.
Julian dates follow the number of days in the year.
April 9 is the 99th day of 1999 and has a Julian date of 9999. It wasn't used in embedded microchips. However, like any other potential threat to our operations we took prudent measures and heightened our situational awareness to ensure ACC remained ready. However, members of the Air Force's Y2K Program Office staffed a Y2K Help Desk overnight as a precautionary measure, said Milz. While ACC didn't staff a Help Desk here, there are other precautionary measures already in effect.
