# ReferenceDay

Syntax:

ReferenceDay

The setting defines which day in January to set as reference day to define week 1. By default, QlikView functions use 4 as the reference day. This means that week 1 must contain January 4, or put differently, that week 1 must always have at least 4 days in January.

The following values can be used to set a different reference day:

* 1 (= January 1)
* 2 (= January 2)
* 3 (= January 3)
* 4 (= January 4)
* 5 (= January 5)
* 6 (= January 6)
* 7 (= January 7)

Examples:

`Set ReferenceDay=3; //(set January 3 as the reference day)`
