C Julian Date Conversion Charts

This appendix contains the topic:

C.1 About the Julian Date Format

Date fields in JD Edwards World files are stored in the Julian format. Program X0028 converts these dates into the Gregorian format so they are easily recognized in World software applications.

If you are performing date calculations in World Writer, you may be required to use the Julian date value. These conversion charts will assist in determining the value to enter.

They are also useful when viewing Julian date fields in applications outside of JD Edwards World that do not convert Julian to Gregorian.

The Julian (*JUL) date format is CYYDDD, where:

C is added to 19 to create the century, i.e. 0 + 19 = 19, 1 + 19 = 20. YY is the year within the century, DDD is the day in the year.
