Built In 'Post' Archive Ignored Using is_post_type_archive()

[Howdy_McGee]

I've tested this a couple times and using the built-in post type "Post" archives then testing against is_post_type_archive( 'post' ) always returns false. It does get caught by the catch-all is_archive() on the other-hand.

The expected outcome is when viewing Post Archives to be able to use is_post_type_archive( 'post' ) to specifically target Post Archives.

A quick way to test this is to add this under wp_head()

if( is_post_type_archive( 'post' ) ) {
	die( 'Post Archive' );
} else if( is_archive() ) {
	die( 'All Archives' );
}

Which always evaluates to false on Post Archives.

The linked ticket is not really a duplicate. They're addressing an issue ( over 2 years old ) with is_post_type_archive( 'post' ) working for Front Page or Blog but this issue regards actual Post Archives, Month / Year Archives. There's already is_category() for blog categories, is_tag() for tags, is_author() for Authors, but nothing specifically targets Post Date Archive Pages.

The real issue is that on Month / Year Archive Pages, is_post_type_archive( 'post' ) will always return false on those pages so to target those specific pages you have to use is_archive() which will also catch Post Type Archives. You're forced to have your Post Type Archive conditionals at the top and actual Post Archive is_archive() conditional at the bottom, which even then may catch unintended post type archives.

This isn't documented very well in the Codex or Code Reference and I feel is really a bug.

There's an explanation from nacin why is_post_type_archive() works the way it does.

There's already is_category() for blog categories, is_tag() for tags, is_author() for Authors, but nothing specifically targets Post Date Archive Pages.

is_date() does: ​https://codex.wordpress.org/Function_Reference/is_date.
