The DatePeriod Class

The DatePeriod class creates a sequence of dates between start and end points with a specific interval. Accepts parameters: start date as a DateTime object, interval as a DateInterval object, number of recurrences or end date. Allows iterating over all dates in the specified range.

Syntax

new DatePeriod(DateTime $start, DateInterval $interval, int $recurrences);

new DatePeriod(DateTime $start, DateInterval $interval, DateTime $end);

Example

Let's create a period of 5 dates with an interval of 1 day:

<?php
	$start = new DateTime('2025-01-01');
	$interval = new DateInterval('P1D');
	$period = new DatePeriod($start, $interval, 4);
	
	foreach ($period as $date) {
		echo $date->format('Y-m-d') . '<br>';
	}
?>

Code execution result:

'2025-01-01'
'2025-01-02'
'2025-01-03'
'2025-01-04'
'2025-01-05'

Example

Let's create a period between two dates with an interval of 1 week:

<?php
	$start = new DateTime('2025-01-01');
	$end = new DateTime('2025-02-01');
	$interval = new DateInterval('P1W');
	$period = new DatePeriod($start, $interval, $end);

	foreach ($period as $date) {
		echo $date->format('Y-m-d') . '<br>';
	}
?>

Code execution result:

'2025-01-01'
'2025-01-08'
'2025-01-15'
'2025-01-22'
'2025-01-29'
