Чтобы выяснить количество рабочих дней с учетом праздников и выходных - суббота и воскресенье
<?php
function Count_Days_Without_Weekends($endDate,$startDate,$holidays){
$endDate = strtotime($endDate.' 00:00:00');
$startDate = strtotime($startDate.' 00:00:00');
$days = ($endDate - $startDate) / 86400 + 1;
$no_full_weeks = floor($days / 7);

}Для этого выполните вызов функции:
//количество рабочих дней с учетом праздников и выходных - суббота и воскресенье
echo Count_Days_Without_Weekends(
'31.01.2023', //конец интервала
'01.01.2023', //начало интервала
[
'02.01.2023', //праздники:
'03.01.2023',
'04.01.2023',
'05.01.2023',
'06.01.2023',
]
);
