DAY

DAY is the day number of stop time of scan. Day 1 is the first day of the month specified with the MONTH parameter, which defaults to 1 so that DAY is the day of year. If LST was specified, DAY must be the (modified?) local sidereal day number for the reference station. These numbers are printed on the right side of VLA monthly schedules and are near 56800 in 1996.
