Notes

The dates and times in this schedule may not agree with those on other online launch schedules, including the official Vandenberg AFB schedule because different sources were used, the information was interpreted differently, and the schedules were updated at different times.
The webmaster does not post the dates, launch windows, and times for military launches until they have been officially released by the Defense Department.
All launch dates and times are given in Pacific Time using a 24-hour format similar to military time (midnight = 00:00, 1:00 p.m. = 13:00, 11:00 p.m. = 23:00, etc.).
The above schedule makes no distinction between Pacific Standard Time (PST) and Pacific Daylight Saving Time (PDT). PST is in effect from the first Sunday in November to the second Sunday in March. PDT is in effect from the second Sunday in March to the first Sunday in November.
The Pacific Time zone lags UTC by 7 or 8 hours, depending on the time of year. The time difference is as follows:
2018 MAR 11 - 2018 NOV 4: Pacific Time = UTC -7 hours

2018 NOV 4 - 2019 MAR 10: Pacific Time = UTC -8 hours
Launch dates are fluid and tend to change over time.
Launches for all vehicles except the Pegasus XL are scheduled for the start of the launch window. Pegasus XL launch times are scheduled for the middle of the launch window.
Prior to the launch of a classified payload, the exact launch time is kept secret until about T-18 to T-4 hours. The launch window is also secret and not made public. Instead of providing the launch window, the Air Force announces a launch period - a large block of time within which the launch window falls.
