Hi Cindy!

I guess it comes from years of being a government employee in the past. Julian dates and the count of days that have elapsed in the year (i.e. 2003027 for today, January 27, 2003) is not the same thing. Although I agree with you that many use the 2nd method for storing days and it is a good way of tracking dates but also not truly a Julian date. It could create a problem later extracting the dates and converting them back if the 'actual method of initial conversion' is not known.

>>.... a Julian Day Number is a count of days that have elapsed since Greenwich mean time at noon on 1 January 4713 B.C. The Julian Date is the Julian day number followed by the fraction of the day elapsed since the preceding noon. The julian date for today after 12:00 noon would be 2452667, not 2003027. Did I miss something?

>The first time I heard of "Julian day" was to describe the Nth day of the year - February 1 is day number 32. The terminology may be mis-applied, but defining days in that way makes working with dates easy.
