php get days between two dates code example

Example 1: php calculate date difference

//get Date diff as intervals 
$d1 = new DateTime("2018-01-10 00:00:00");
$d2 = new DateTime("2019-05-18 01:23:45");
$interval = $d1->diff($d2);
$diffInSeconds = $interval->s; //45
$diffInMinutes = $interval->i; //23
$diffInHours   = $interval->h; //8
$diffInDays    = $interval->d; //21
$diffInMonths  = $interval->m; //4
$diffInYears   = $interval->y; //1

//or get Date difference as total difference
$d1 = strtotime("2018-01-10 00:00:00");
$d2 = strtotime("2019-05-18 01:23:45");
$totalSecondsDiff = abs($d1-$d2); //42600225
$totalMinutesDiff = $totalSecondsDiff/60; //710003.75
$totalHoursDiff   = $totalSecondsDiff/60/60;//11833.39
$totalDaysDiff    = $totalSecondsDiff/60/60/24; //493.05
$totalMonthsDiff  = $totalSecondsDiff/60/60/24/30; //16.43
$totalYearsDiff   = $totalSecondsDiff/60/60/24/365; //1.35

Example 2: Get the number of days between two dates in PHP

$startDate = new DateTime("2019-10-27");
$endDate = new DateTime("2020-04-11");

$difference = $endDate->diff($startDate);
echo $difference->format("%a");

Example 3: php get day diff

$now = time(); // or your date as well
$your_date = strtotime("2010-01-31");
$datediff = $now - $your_date;

echo round($datediff / (60 * 60 * 24));

Example 4: php get date between two dates

$period = new DatePeriod(
     new DateTime('2010-10-01'),
     new DateInterval('P1D'),
     new DateTime('2010-10-05')
);

//Which should get you an array with DateTime objects. 

//To iterate

foreach ($period as $key => $value) {
    //$value->format('Y-m-d')       
}

Example 5: how to calculate days between two dates in php

<?php
function dateDifference($start_date, $end_date)
{
    // calulating the difference in timestamps 
    $diff = strtotime($start_date) - strtotime($end_date);
     
    // 1 day = 24 hours 
    // 24 * 60 * 60 = 86400 seconds
    return ceil(abs($diff / 86400));
}
 
// start date 
$start_date = "2016-01-02";
 
// end date 
$end_date = "2016-01-21";
 
// call dateDifference() function to find the number of days between two dates
$dateDiff = dateDifference($start_date, $end_date);
 
echo "Difference between two dates: " . $dateDiff . " Days ";
?>

Example 6: find days with name between two dates in php

$from_date ='01-01-2013';
$to_date ='05-01-2013';

$from_date = new DateTime($from_date);
$to_date = new DateTime($to_date);

for ($date = $from_date; $date <= $to_date; $date->modify('+1 day')) {
  echo $date->format('l') . "\n";
}
