| Hi, You can use the solution below to calculate the number of business days between two dates. The function works with date format YYYY-MM-DD. Holidays and national days have to be added to $holidays array. When starting date is the same as end date, the function will return zero business days. function calculateBusinessDays($startDate,$endDate) { if ( strtotime($endDate) >= strtotime($startDate) ) { $holidays = array("2020-12-24","2020-12-25","2020-12-26"); $date = $startDate; $days = 0; while ($date != $endDate) { $date = date("Y-m-d", strtotime("+1 day", strtotime($date))); $weekday = date("w", strtotime($date)); if ( $weekday != 6 AND $weekday != 0 AND !in_array($date, $holidays) ) $days++; } return $days; } else { return "Please check the dates."; } } echo calculateBusinessDays("2020-07-14","2020-07-17"); The function will calculate, that difference between 2020-07-14 and 2020-07-17 is 3 business days. | |||||||||||
