DAYOFWEEK

Syntax

DAYOFWEEK(date)

Description

Returns the day of the week index for the date (1 = Sunday, 2 = Monday, ..., 7 = Saturday). These index values correspond to the ODBC standard.

This contrasts with WEEKDAY() which follows a different index numbering (0 = Monday, 1 = Tuesday, ... 6 = Sunday).

Examples
