Re: Adding 1 to date


The reason I prefer Lilian to Julian is that Julian won't work properly across years. A Julian date consists of the year followed by the day number within the year. Since December 31 is the 365th day of the year, the last day of this year is 05365 in Julian format.

If you add 1 to 05365, you get 05366 which isn't a valid Julian date.

When you use Lilian dates (see my other message for an example) you don't have this problem.

You could use the CVTDAT command to convert the date to Julian format,
add 1 then CVTDAT back to the original format.
