WorkdayHelper

Count workdays and list holiday events in a range of dates with PHP taking care of public holidays and other custom closing days.

Inspired by Massimo Simonini getWorkdays() Gist. @see https://gist.github.com/massiws/9593008

Benefits and features:

you can specify a range of working days in a week (from Monday to Sunday);
you can add custom holidays and business closures, for example as a result of a database query;
it returns a calendar of holidays for that specific range of dates;
you can use your custom recursive holiday calendar (see $publicHolidays);
it takes care of the timezone of your application;
it automatically calculates Easter, and Easter mondays taking care of the timezone (requires PHP with ext-calendar);

Requirements

PHP 5.6.0 and later

Composer

The preferred way to install this extension is through composer.

Either run

composer require --prefer-dist letsjump/workday-helper-php

or add

"letsjump/workday-helper-php": "~1.0.0"

to the require section of your composer.json.

Manual Installation

If you do not wish to use Composer, you can download the latest release.

require_once('/path/to/workday-helper-php/WorkdayHelper.php');

Dependencies

PHP ext-calendar

To automatically calculate Easter dates, you have to compile PHP with --enable-calendar. See ext-calendar. You can refer to this Stack Overflow question if you are in a Docker environment.

If your PHP isn't compiled with ext-calendar and if you cannot compile it, please set $calculateEaster to false otherwhise WorkingdayHelper will throw an exception.

Usage:

Count the days worked in January while working from Monday to Friday, taking care of public holidays:

use letsjump\workdayHelper\WorkdayHelper;

$closingDays                 = new WorkdayHelper('2021-01-01', '2021-01-31');
$closingDays->workingDays    = [1, 2, 3, 4, 5];

echo $closingDays->getWorkdays(); // (19 days)

count the day worked in april while working Monday, Wednesday and Friday, taking care of public holidays:

$closingDays                 = new WorkdayHelper('2021-04-01', '2021-04-30');
$closingDays->workingDays    = [1, 3, 5];
echo $closingDays->getWorkdays(); // (12 days)

Add a strike to the custom closing days

$closingDays                 = new WorkdayHelper('2021-01-01', '2021-01-31');
$closingDays->workingDays          = [1, 2, 3, 4, 5];
$closingDays->customClosing = [
     [
         'date'    => '2021-01-18',
         'event'   => 'Strike!',
         'options' => [
             'employee_id'        => 345,
             'htmlClass' => 'deep-purple'
         ]
     ],
];
echo $closingDays->getWorkdays(); // (18 days)

Get the calendar with all the closing days for a specific date interval

$closingDays                 = new WorkdayHelper('2021-01-01', '2021-12-31');
$closingDays->workingDays          = [0, 1, 2, 3, 4, 5, 6]; // don't forget to set every day of the week!

<table>
<?php foreach ($closingDays->getCalendar() as $holiday): ?>
<tr>
     <td><?= $holiday['date'] ?></td>
     <td><?= $holiday['event'] ?></td>
</tr>
<?php endforeach ?>
</table>

Add custom closings

Custom closure is an array of events. Each event is an array with this configuration:

example

$myInstantatedClass->customClosing = [
         [
             'date'  => '2021-01-10',
             'event' => 'Chiusura per ferie'
         ],
         [
             'date'    => '2021-01-05',
             'event'   => 'Strike!',
             'options' => [
                  'id'        => 345,
                  'htmlClass' => 'green'
             ]
         ],
          ...
];

Replace the default recursive holiday calendar

The default recursive holiday calendar is an array of events. Each event is an array with this configuration:

example

$myInstantatedClass->publicHolidays = [
         [
             'm-d'  => '12-25',
             'event' => 'Christmas'
         ],
         [
             'm-d'    => '12-26',
             'event'   => 'Boxing day',
             'options' => [
                  'id'        => 345,
                  'htmlClass' => 'green'
             ]
         ],
          ...
];

Holiday calendar

The holiday calendar returns a list of holidays for the working days in the given date range. So if you want to retrive all the closing days in that date range you should set all the days of the week into the $workingDays Array E.G. $myWorkDay->workingDays[0,1,2,3,4,5,6].

The output is an array of events. Each array has the unix timestamp of the holiday as key and contains:

Example

      [
         [1609455600] => [
             [unixTimestamp] => 1609455600,
             [date] => 2021-01-01, # control the format with $outputFormat property
             [event] => Capodanno, # description of the event
             [type] => public, #public / custom
             [options] => # custom option passed by the $customClosing or the $publicHolidays Array
         ],
         ...
      ]

Side notes

The recursive holiday and the default date format are localized for Italy. I know it's not the right way to work, but I need to quickly develop an application for a customer. If you want to use your localization, please refer to Replace the default recursive holiday calendar. If you plan to use intensively in your application, you may extend the base class and configure there the basic properties.
