DoW Function

Extract the number of the day of the week from a date.

Namespace: XSharp.RT
Assembly: XSharp.RT (in XSharp.RT.dll) Version: 2.21

Syntax

Copy

 FUNCTION DoW(
	dDate AS DATE
) AS DWORD

public static uint DoW(
	Date dDate
)

Request Example View Source

Parameters

dDate: Type: Date
The date.

Return Value

Type: DWord
The day of the week as a number from 1 to 7, where 1 is Sunday, 2 is Monday, and so on.
For an invalid or NULL_DATE, DoW() returns 0.

Remarks

DoW() is a date conversion function that converts a date value to a number identifying the day of the week.
It is useful when you want date calculations on a weekly basis. DoW() is similar to CDoW(), which returns the day of week as a string instead of a number.

Examples

These examples illustrate CDoW() and its relationship to DoW():

Copy

1? TODAY()                        // 09/01/98
2? DOW(TODAY())                    // 3
3? CDOW(TODAY())                // Tuesday
4? DOW(TODAY() - 2)                // 1
5? CDOW(TODAY() – 2)                // Sunday
