How to find first day of the next month and remaining days till this date with PHP

Question

How can I find first day of the next month and the remaining days till this day from the present day?

Thank you

Answer 1

Create a timestamp for 00:00 on the first day of next month:

$firstDayNextMonth = strtotime('first day of next month');

The number of days til that date is the number of seconds between now and then divided by (24 * 60 * 60).

$daysTilNextMonth = ($firstDayNextMonth - time()) / (24 * 3600);

Answer 2

$firstDayNextMonth = date('Y-m-d', strtotime('first day of next month'));

For getting first day after two months from current

$firstDayAfterTwoMonths = date('Y-m-d', strtotime('first day of +2 month'));

Answer 3

You can use DateTime object like this to find out the first day of next month like this:

$date = new DateTime('first day of next month');

You can do this to know how many days left from now to the first day of next month:

$date = new DateTime('now');
$nowTimestamp = $date->getTimestamp();
$date->modify('first day of next month');
$firstDayOfNextMonthTimestamp = $date->getTimestamp();
echo ($firstDayOfNextMonthTimestamp - $nowTimestamp) / 86400;

Answer 4

The easiest and quickest way is to use strtotime() which recognizes 'first day next month';

$firstDayNextMonth = date('Y-m-d', strtotime('first day next month'));

Answer 5

Since I googled this and came to this answer, I figured I'd include a more modern answer that works for PHP 5.3.0+.

//Your starting date as DateTime
$currentDate = new DateTime(date('Y-m-d'));

//Add 1 month
$currentDate->add(new DateInterval('P1M'));

//Get the first day of the next month as string
$firstDayOfNextMonth = $currentDate->format('Y-m-1');

Answer 6

$firstDayNextMonth = date('Y-m-d', mktime(0, 0, 0, date('m')+1, 1, date('Y')));

Answer 7

You can get the first of the next month with this:

$now = getdate();
$nextmonth = ($now['mon'] + 1) % 13 + 1;
$year = $now['year'];
if($nextmonth == 1)
    $year++;
$thefirst = gmmktime(0, 0, 0, $nextmonth, $year);

With this example, $thefirst will be the UNIX timestamp for the first of the next month. Use date to format it to your liking.

This will give you the remaining days in the month:

$now = getdate();
$months = array(
    31,
    28 + ($now['year'] % 4 == 0 ? 1 : 0), // Support for leap years!
    31,
    30,
    31,
    30,
    31,
    31,
    30,
    31,
    30,
    31
);
$days = $months[$now['mon'] - 1];
$daysleft = $days - $now['mday'];

The number of days left will be stored in $daysleft.

Hope this helps!

As another poster has mentioned the DateInterval object does not give accurate results for the next month when you use dates such as 1/31/2016 or 8/31/2016 as it skips the next month. My solution was to still use the DateInterval object but reformat your current date to be the first day of the current month prior to utilizing the DateInterval.

$currentDate = '8/31/2016';
$date = new DateTime(date("n", strtotime($currentDate))."/1/".date("Y", strtotime($currentDate)));
//add 1 month
$date->add(new DateInterval('P1M'));
$currentDate=$date->format('m/1/Y'); 

echo($currentDate);

Answer 9

easiest way to get the last day of the month

date('Y-m-d', mktime(0, 0, 0, date('m')+1, 1, date('Y')));

Answer 10

I took mattbasta's approach because it's able to get the 'first day of next month' with a given date, but there is a tiny problem in calculating the $nextmonth. The fix is as below:

$now = getdate();
$nextmonth = ($now['mon'] + 1) % 13 + 1;
$year = $now['year'];
if($nextmonth == 1)
    $year++;
else
    $nextmonth--;
$thefirst = gmmktime(0, 0, 0, $nextmonth, $year);

Answer 11

I initially thought about using a DateInterval object (as discussed above in another answer) but it is not reliable. For example, if the current DateTime is 31 January and then we add on a month (to get the next month) then it will skip February completely!

Here is my solution:

function start_of_next_month(DateTime $datetime)
{
    $year = (int) $datetime->format('Y');
    $month = (int) $datetime->format('n');
    $month += 1;

    if ($month === 13)
    {
        $month = 1;
        $year += 1;
    }

    return new DateTime($year . '-' . $month . '-01');
}

Answer 12

Even easier way to get first and last day of next month

$first = strttotime("first day of next month");
$last = strttotime("last day of next month");

Answer 13

You could do something like this. To have this functionality, you need to make use of a php library available in https://packagist.org/packages/ishworkh/navigable-date.

With that is really easy to do what you're asking for here. For e.g:

$format = 'Y-m-d H:i:s';

$Date = \NavigableDate\NavigableDateFacade::create('2017-02-24');
var_dump($Date->format($format));

$resetTime = true;
$resetDays = true;

$NextMonth = $Date->nextMonth($resetTime, $resetDays);

var_dump($NextMonth->format($format));

$DayUntilFirstOfNextMonth = $NextMonth->getDifference($Date);

var_dump('Days left:' . $DayUntilFirstOfNextMonth->format('%d'));

gives you ouput:

string(19) "2017-02-24 00:00:00"
string(19) "2017-03-01 00:00:00"
string(11) "Days left:5"

Note: Additionally this library let you navigate through dates by day(s), week(s), year(s) forward or backward. For more information look into its README.

Answer 14

$month = date('m')+1;
if ($month<10) {
    $month = '0'.$month;
}
echo date('Y-').$month.'-01';

Simplest way to achieve this. You can echo or store into variable.

Answer 15

(PHP 5 >= 5.5.0, PHP 7, PHP 8)

To get the first day of next month a clean solution:

<?php
$date = new DateTimeInmutable('now');
$date->modify('first day of next month');//here the magic occurs

echo $date->format('Y-m-d') . '\n';

Since you just want to calculate it I suggest using DateTimeInmutable class. using the class DateTime and $date->modify('first day of next month'); will modify your original date value.

Answer 16

I came up with this for my needs:

if(date('m') == 12) { $next_month = 1; } else { $next_month = date('m')+1; }
if($next_month == 1) { $year_start = date('Y')+1; } else { $year_start = date('Y'); }
$date_start_of_next_month = $year_start . '-' . $next_month . '-01 00:00:00';

if($next_month == 12) { $month_after = 1; } else { $month_after = $next_month+1; }
if($month_after == 1) { $year_end = date('Y')+1; } else { $year_end = date('Y'); }
$date_start_of_month_after_next = $year_end . '-' . $month_after . '-01 00:00:00';

Please note that instead of getting $date_end_of_next_month I chose to go with a $date_start_of_month_after_next date, it avoids the hassles with leap years and months containing different number of days. You can simply use the >= comparaision sign for $date_start_of_next_month and the < one for $date_start_of_month_after_next.

If you prefer a timestamp format for the date, from there you will want to apply the strtotime() native function of PHP on these two variables.

Answer 17

You can use the php date method to find the current month and date, and then you would need to have a short list to find how many days in that month and subtract (leap year would require extra work).
