Syntax Syntax

WP_Date_Query::__construct( array $date_query, string $default_column = 'post_date' )

Description Description

Time-related parameters that normally require integer values (‘year’, ‘month’, ‘week’, ‘dayofyear’, ‘day’, ‘dayofweek’, ‘dayofweek_iso’, ‘hour’, ‘minute’, ‘second’) accept arrays of integers for some values of ‘compare’. When ‘compare’ is ‘IN’ or ‘NOT IN’, arrays are accepted; when ‘compare’ is ‘BETWEEN’ or ‘NOT BETWEEN’, arrays of two valid values are required. See individual argument descriptions for accepted values.
