Show working days of a month excluding weekends with PHP

This tutorial will show you how to get the individual working dates of a month, whilst removing weekends, this is useful for creating charts for instance.

First create an empty array it will later store the dates.

Next I’m making use of a native function to inform php which type of calendar were working this, in this case its an Gregorian Calendar

Next set the current month and year and get the total number of days in the current month using another inbuilt function: cal_days_in_month.

$month = date('n'); // Month ID, 1 through to 12. $year = date('Y'); // Year in 4 digit 2009 format. $day_count = cal_days_in_month($type, $month, $year); // Get the amount of days

Next create a for loop to loop through the number of days of the month then format the date for each day extract the day name and check the day is not a Sun or Sat then add that date to an array called $workdays

//loop through all days for ($i = 1; $i >

From here you’ve got all the dates stored in an array to use.

To just see the array contents we can use print_r:

To use the array you could use a foreach:

 foreach ($workdays as $key=>$value) < //do something here >

$workdays = array(); $type = CAL_GREGORIAN; $month = date('n'); // Month ID, 1 through to 12. $year = date('Y'); // Year in 4 digit 2009 format. $day_count = cal_days_in_month($type, $month, $year); // Get the amount of days //loop through all days for ($i = 1; $i > // look at items in the array uncomment the next line //print_r($workdays);

PHP: Calculate the Number of Working Days in a Month

How to calculate the number of working days in a month, in other words discount Saturdays and Sundays from a month’s total number of days.

It sounds pretty simple, but because of the shifting nature of the calendar we use, one can’t just take a guess and average it you know. No, we need a function to work out this total for each month of any particular year.

Now of course I’m sure there are for more acute, beautiful or elegant solutions to this particular problem out there, but I for one quite like the idea of seeing the logic behind what is happening step by step, which is exactly why I came up with this little function to do the work for me.

So in order to calculate the number of working days in a month by removing Saturdays and Sundays from its day count, have a look at this simple PHP function:

function calculateWorkingDaysInMonth($year = '', $month = '') < //in case no values are passed to the function, use the current month and year if ($year == '') < $year = date('Y'); >if ($month == '') < $month = date('m'); >//create a start and an end datetime value based on the input year $startdate = strtotime($year . '-' . $month . '-01'); $enddate = strtotime('+' . (date('t',$startdate) - 1). ' days',$startdate); $currentdate = $startdate; //get the total number of days in the month $return = intval((date('t',$startdate)),10); //loop through the dates, from the start date to the end date while ($currentdate $currentdate = strtotime('+1 day', $currentdate); > //end date walk loop //return the number of working days return $return; >

As you can see, the logic of the function is pretty straightforward to follow. To use the function in your code, simply call it and pass the month and year you want it to examine, meaning that
