is_month() │ WP 1.5.0

Determines whether a monthly archive page is shown (example.com/2009/08) — page with posts for a specific month. A conditional tag.

This function is a part of is_date() and is_archive() check, so if you use them together, you should use is_month() before those functions, otherwise is_month() condition will never occur.

Uses: WP_Query::is_month()
1 time — 0.00007 sec (very fast) | 50000 times — 0.02 sec (speed of light)

No Hooks.

Return

true|false. Whether the query is for an existing month archive.

Usage

if( is_month() ){
	// ...
}

Examples

0

#1 Display text only on monthly archive pages 

if( is_year() ){
	echo 'This is a monthly archive page!';
}
0

#2 Use of is_archive() and is_month() together in if/else statements 

if( is_month() )
	echo 'This is a monthly archive page!';
elseif( is_archive() )
	echo 'An archive page.';

So is_archive() should follow is_month(), otherwise is_month() condition will never occur.
