How to find number of days between two dates using PHP?
34 Answers
$now = time(); // or your date as well
$your_date = strtotime("2010-01-31");
$datediff = $now - $your_date;
echo round($datediff / (60 * 60 * 24));
Convert your dates to unix timestamps, then substract one from the another. That will give you the difference in seconds, which you divide by 86400 (amount of seconds in a day) to give you an approximate amount of days in that range.
If your dates are in format 25.1.2010, 01/25/2010 or 2010-01-25, you can use the strtotime function:
$start = strtotime('2010-01-25');
$end = strtotime('2010-02-20');
$days_between = ceil(abs($end - $start) / 86400);
Using ceil rounds the amount of days up to the next full day. Use floor instead if you want to get the amount of full days between those two dates.
If your dates are already in unix timestamp format, you can skip the converting and just do the $days_between part. For more exotic date formats, you might have to do some custom parsing to get it right.
Used this :)
$days = (strtotime($endDate) - strtotime($startDate)) / (60 * 60 * 24);
print $days;
Now it works
You can find dates simply by
<?php
$start = date_create('1988-08-10');
$end = date_create(); // Current time and date
$diff = date_diff( $start, $end );
echo 'The difference is ';
echo $diff->y . ' years, ';
echo $diff->m . ' months, ';
echo $diff->d . ' days, ';
echo $diff->h . ' hours, ';
echo $diff->i . ' minutes, ';
echo $diff->s . ' seconds';
// Output: The difference is 28 years, 5 months, 19 days, 20 hours, 34 minutes, 36 seconds
echo 'The difference in days : ' . $diff->days;
// Output: The difference in days : 10398
Calculate the difference between two dates:
$date1=date_create("2013-03-15");
$date2=date_create("2013-12-12");
$diff=date_diff($date1,$date2);
echo $diff->format("%R%a days");
Output: +272 days
The date_diff() function returns the difference between two DateTime objects.
You can try the code below:
$dt1 = strtotime("2019-12-12"); //Enter your first date
$dt2 = strtotime("12-12-2020"); //Enter your second date
echo abs(($dt1 - $dt2) / (60 * 60 * 24));
number of days between two dates in PHP
function dateDiff($date1, $date2) //days find function
{
$diff = strtotime($date2) - strtotime($date1);
return abs(round($diff / 86400));
}
//start day
$date1 = "11-10-2018";
// end day
$date2 = "31-10-2018";
// call the days find fun store to variable
$dateDiff = dateDiff($date1, $date2);
echo "Difference between two dates: ". $dateDiff . " Days ";
If you have the times in seconds (I.E. unix time stamp) , then you can simply subtract the times and divide by 86400 (seconds per day)
Easiest way to find the days difference between two dates
$date1 = strtotime("2019-05-25");
$date2 = strtotime("2010-06-23");
$date_difference = $date2 - $date1;
$result = round( $date_difference / (60 * 60 * 24) );
echo $result;
$diff = strtotime('2019-11-25') - strtotime('2019-11-10');
echo abs(round($diff / 86400));
If you want to echo all days between the start and end date, I came up with this :
$startdatum = $_POST['start']; // starting date
$einddatum = $_POST['eind']; // end date
$now = strtotime($startdatum);
$your_date = strtotime($einddatum);
$datediff = $your_date - $now;
$number = floor($datediff/(60*60*24));
for($i=0;$i <= $number; $i++)
{
echo date('d-m-Y' ,strtotime("+".$i." day"))."<br>";
}
This code worked for me and tested with PHP 8 version :
function numberOfDays($startDate, $endDate)
{
//1) converting dates to timestamps
$startSeconds = strtotime($startDate);
$endSeconds = strtotime($endDate);
//2) Calculating the difference in timestamps
$diffSeconds = $startSeconds - $endSeconds;
//3) converting timestamps to days
$days=round($diffSeconds / 86400);
/* note :
1 day = 24 hours
24 * 60 * 60 = 86400 seconds
*/
//4) printing the number of days
printf("Difference between two dates: ". abs($days) . " Days ");
return abs($days);
}
<?php
$date1=date_create("2013-03-15");
$date2=date_create("2013-12-12");
$diff=date_diff($date1,$date2);
echo $diff->format("%R%a days");
?>
used the above code very simple. Thanks.
function get_daydiff($end_date,$today)
{
if($today=='')
{
$today=date('Y-m-d');
}
$str = floor(strtotime($end_date)/(60*60*24)) - floor(strtotime($today)/(60*60*24));
return $str;
}
$d1 = "2018-12-31";
$d2 = "2018-06-06";
echo get_daydiff($d1, $d2);
Using this simple function. Declare function
<?php
function dateDiff($firstDate,$secondDate){
$firstDate = strtotime($firstDate);
$secondDate = strtotime($secondDate);
$datediff = $firstDate - $secondDate;
$output = round($datediff / (60 * 60 * 24));
return $output;
}
?>
and call this function like this where you want
<?php
echo dateDiff("2018-01-01","2018-12-31");
// OR
$firstDate = "2018-01-01";
$secondDate = "2018-01-01";
echo dateDiff($firstDate,$secondDate);
?>
Looking all answers I compose universal function what working on all PHP versions.
if(!function_exists('date_between')) :
function date_between($date_start, $date_end)
{
if(!$date_start || !$date_end) return 0;
if( class_exists('DateTime') )
{
$date_start = new DateTime( $date_start );
$date_end = new DateTime( $date_end );
return $date_end->diff($date_start)->format('%a');
}
else
{
return abs( round( ( strtotime($date_start) - strtotime($date_end) ) / 86400 ) );
}
}
endif;
In the general, I use 'DateTime' to find days between 2 dates. But if in the some reason, some server setup not have 'DateTime' enabled, it will use simple (but not safe) calculation with 'strtotime()'.
I read all previous solutions, none of them use PHP 5.3 tools: DateTime::Diff and DateInterval::Days
DateInterval::Days contains exactly the right numbers of days between to date. It is not necessary to create something special and bizarre.
/**
* We suppose that PHP is configured in UTC
* php.ini configuration:
* [Date]
* ; Defines the default timezone used by the date functions
* ; http://php.net/date.timezone
* date.timezone = UTC
* @link http://php.net/date.timezone
*/
/**
* getDaysBetween2Dates
*
* Return the difference of days between $date1 and $date2 ($date1 - $date2)
* if $absolute parameter is false, the return value is negative if $date2 is after than $date1
*
* @param DateTime $date1
* @param DateTime $date2
* @param Boolean $absolute
* = true
* @return integer
*/
function getDaysBetween2Dates(DateTime $date1, DateTime $date2, $absolute = true)
{
$interval = $date2->diff($date1);
// if we have to take in account the relative position (!$absolute) and the relative position is negative,
// we return negatif value otherwise, we return the absolute value
return (!$absolute and $interval->invert) ? - $interval->days : $interval->days;
}
echo '<h3>2020-03-01 - 2020-02-01: 29 days as it\'s a standard leap year</h3>';
echo getDaysBetween2Dates(new DateTime("2020-03-01"), new DateTime("2020-02-01"), false);
echo '<h3>1900-03-01 - 1900-02-01: 28 days as it\'s a "standard" century</h3>';
echo getDaysBetween2Dates(new DateTime("1900-03-01"), new DateTime("1900-02-01"), false);
echo '<h3>2000-03-01 - 2000-02-01: 29 days as it\'s a century multiple of 400: 2000=400x5</h3>';
echo getDaysBetween2Dates(new DateTime("2000-03-01"), new DateTime("2000-02-01"), false);
echo '<h3>2020-03-01 - 2020-04-01: -28 days as 2020-03-01 is before 2020-04-01</h3>';
echo getDaysBetween2Dates(new DateTime("2020-02-01"), new DateTime("2020-03-01"), false);
I have tried almost all of the ways as in answers given. But neither DateTime nor date_create gave me correct answers in all my test cases. Specially test with February & March dates or December & January dates.
So, I came-up with mixed solution.
public static function getMonthsDaysDiff($fromDate, $toDate, $includingEnding = false){
$d1=new DateTime($fromDate);
$d2=new DateTime($toDate);
if($includingEnding === true){
$d2 = $d2->modify('+1 day');
}
$diff = $d2->diff($d1);
$months = (($diff->format('%y') * 12) + $diff->format('%m'));
$lastSameDate = $d1->modify("+$months month");
$days = date_diff(
date_create($d2->format('Y-m-d')),
date_create($lastSameDate->format('Y-m-d'))
)->format('%a');
$return = ['months' => $months,
'days' => $days];
}
I know, performance wise this quite expensive. And you can extend it to get Years as well.
