Overview
Syntax | DATESUBDATE(Date1,Date2,Op) | Returns the time interval between two dates. |
Parameter 1 | Date1 | The Date1 and Date2 parameters specify the two dates to be entered. If the value of Date1 is earlier than that of Date2, a negative value is returned. If the value of Date1 is later than that of Date2, a positive value is returned. If the values of Date1 and Date2 are of the numeric types, the serial number logic of the 1990 date system will be followed. For example, the serial number 35796 represents January 1, 1998.  Note: |
Parameter 2 | Date2 | |
Parameter 3 | Op | The Op parameter specifies the time unit of the returned value. The options for the unit include s/S (second), m/M (minute), h/H (hour), d/D (day), and w/W (week). |
