Discussion
JTODATE() converts a Julian date (which is an integer value measured in days) to an Alpha Anywhere Date value. After you have used JDATE() to convert dates to numbers (in order to perform computations on them), you can use JTODATE() to display the results as Dates. NOTE: JDATE() now returns values in a numeric format compatible with input to JTODATE(). For example, if the current date is 9/21/1995, then:
? jdate({09/21/1995})
= 2449982.000000
? jtodate(2449982.000000)
= {09/21/1995}Example
' if the current date is 9/21/1995
? jtodate( jdate( DATE() + 7) )
= {09/28/1995}How to Import a Julian Date
