LONGDATE(Date)
String Expression
Converts a numeric date value to a long-string form that can be used to display in question text, Edit Elements, or Information Elements.
Examples:
LONGDATE(DATEYMD(1980,8,12)) returns "Tuesday, August 12, 1980"
LONGDATE(TODAY) returns "Wednesday, October 31, 2017"
LONGDATE(TODAY – 60) returns "Saturday, September 1, 2017"
You can also use date components from other Data Element, Date type items; for example where DATE is the variable name of the Date type item:
LONGDATE(DATEYMD(DATEY,DATEM,DATED))
This would give you the same result as:
LONGDATE(DATE)
