is_day() WP 1.5.0
Determines whether a day archive page is shown (example.com/2009/08/05) — page with posts for a specific day. 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_day() before those functions, otherwise is_day() condition will never occur.
Works based on: WP_Query::is_day()
1 time = 0.00007s = very fast | 50000 times = 0.02s = speed of light
No Hooks.
Return
true/false. Whether the query is for an existing day archive.
Usage
if( is_day() ){ // ... }
Examples
#1 Display text only on day archive pages
if( is_day() ){ echo "This page is a page for 2019/08/15 [and link to example.com/2009/08/15]"; }
#2 Use of is_date() and is_day() together in if/else statements
if( is_day() ) echo 'This is a day archive page.'; elseif( is_date() ) echo 'This is a date archive page, for any date.'; else echo 'This is not a date archive page';
So is_archive() should follow is_day(), otherwise is_day() condition will never occur.
