Return Value

INTEGER

Syntax

WEEKOF(date-expression)

Arguments

date-expression: An expression that has the DATE data type, or a text expression that specifies a date. The values of the text expression are converted automatically to DATE values, using the current setting of the DATEORDER option to resolve any ambiguity.

Notes

Determining Week 1

The value of WEEKDSYSNEWYEAR specifies how many days of the new year there must be in the week for WEEKOF to consider it to be week 1 of the new year. For example, when January 1 is on a Wednesday, then the week of December 29 to January 4 has four days in the new year. WEEKDSYSNEWYEAR must therefore have a value of 4 or less for that week to be counted as week 1. This determination of week 1 affects the numbering of all weeks in the year.
