Description

Julian day as a decimal. Julian date which is the time elapsed in days from 00:00 on January 1st 4713 BC. Julian Date (chronological).

For reference: Julian day 2440000 begins at 0000 hours, May 23, 1968.

Please note, Seabird processing software includes a "julianday" which is day of year. That is categorized as a separate term "yrday" at BCO-DMO.
