@djrmom Thanks for this!

For real. I need to do this and yours is the first Google result. Thank you!

Thanks a lot for this one ;)

Thanks, saved some time and effort!

Thanks for this idea. I modified it to take the month out of the date but the sorting then happens alphabetically. Would you know how I can sort it the way the months really are? Thanks.

How to Show 3 months calendar(current month and coming 2 months) instead of the date-picker input field. I am stuck :(

Amazing I just needed this to convert an Advanced Custom Fields (ACF) field date into one that FacetWP could understand.

/**
 * Change ACF field dates to be format that FacetWP understands.
 * Re-index dates in this format.
 * 
 * "Make sure custom field values are stored as YYYY-MM-DD or YYYY-MM-DD HH:MM:SS"

 * @since x.x.x

	if ( $facet_name == $params['facet_name'] ) {

		$params['facet_value'] = date( 'Y-m-d', strtotime( $raw_value ) );
		$params['facet_display_value'] = $params['facet_value'];
