ISSUE SUMMARY:
JS birthday only shows upcoming birthdays but not the todays birthdays. It should as you could send a greeting.

STEPS TO REPLICATE:
1 check birthday of tomorrow (users will have birthday)
2 check tomorrow (users will be hidden and users with birthday tomorrow will be shown)

I could solve it by changing /modules/mod_community_birthdays/helper.php in line 71 from

$query .= " AND DATE_ADD(value, INTERVAL YEAR(CURDATE())-YEAR(value) + IF(DAYOFYEAR(CURDATE()) > DAYOFYEAR(value),1,0) YEAR) BETWEEN CURDATE() AND DATE_ADD(CURDATE(), INTERVAL ".$days." DAY)";

$query .= " AND DATE_FORMAT(value,'%m%d') >= ".date('md');

Hi Guido,

thank you, i will talk this with our developer

cheers!
