How to change arrows on the WordPress calendar widget?

It is coded into the widget so I’m not sure that there is a way. If there is, I don’t see a way that won’t require code – either a hook or a hacky CSS solution.

the calendar widget output (actually the output of the calendar function, regardless where it is used) is run over a filter 'get_calendar'
(see /wp-includes/general-template.php line 1983)

try to add a corresponding filter function into functions.php of your (child) theme;

example for changing the double-arrows:

add_filter( 'get_calendar', 'modify_default_calendar_widget_output' );

function modify_default_calendar_widget_output( $output ) {
	$output = str_replace( '?', 'NEWPREV', $output );
	$output = str_replace( '?', 'NEWNEXT', $output );
	return $output;
}

to remove them, use:

add_filter( 'get_calendar', 'modify_default_calendar_widget_output' );

function modify_default_calendar_widget_output( $output ) {
	$output = str_replace( '?', '', $output );
	$output = str_replace( '?', '', $output );
	return $output;
}

Hi Michael,

Thank you for the response. I tried adding the code you mentioned, but sadly it didn’t change anything regarding the calendar.

I missing something or did I do something wrong?

Regards.

I just noticed that the forum editor converted the & laquo; and & raquo; into the double arrows.
unfortunately, this won’t work.

in the code, replace the left-double-arrow with & laquo; and the right-double-arrow with & raquo; (no space after the &)

tested in a child theme of Twenty Sixteen – however, this is no guarantee that it works in all themes.

It worked! Thank you, Micheal.
