Get Week Number in Month from Date in PHP

Get week number in month from date in PHP?

I think this relationship should be true and come in handy:

Week of the month = Week of the year - Week of the year of first day of month + 1

We also need to make sure that "overlapping" weeks from the previous year are handeled correctly - if January 1st is in week 52 or 53, it should be counted as week 0. In a similar fashion, if a day in December is in the first week of the next year, it should be counted as 53. (Previous versions of this answer failed to do this properly.)

<?php

function weekOfMonth($date) {
    //Get the first day of the month.
    $firstOfMonth = strtotime(date("Y-m-01", $date));
    //Apply above formula.
    return weekOfYear($date) - weekOfYear($firstOfMonth) + 1;
}

function weekOfYear($date) {
    $weekOfYear = intval(date("W", $date));
    if (date('n', $date) == "1" && $weekOfYear > 51) {
        // It's the last week of the previos year.
        return 0;
    }
    else if (date('n', $date) == "12" && $weekOfYear == 1) {
        // It's the first week of the next year.
        return 53;
    }
    else {
        // It's a "normal" week.
        return $weekOfYear;
    }
}

// A few test cases.
echo weekOfMonth(strtotime("2020-04-12")) . " "; // 2
echo weekOfMonth(strtotime("2020-12-31")) . " "; // 5
echo weekOfMonth(strtotime("2020-01-02")) . " "; // 1
echo weekOfMonth(strtotime("2021-01-28")) . " "; // 5
echo weekOfMonth(strtotime("2018-12-31")) . " "; // 6

To get weeks that starts with sunday, simply replace date("W", ...) with strftime("%U", ...).

PHP get number of week for month

The most frustrating thing I have ever tried to get working - but here it is!

<?php

    /**
     * Returns the amount of weeks into the month a date is
     * @param $date a YYYY-MM-DD formatted date
     * @param $rollover The day on which the week rolls over
     */
    function getWeeks($date, $rollover)
    {
        $cut = substr($date, 0, 8);
        $daylen = 86400;

        $timestamp = strtotime($date);
        $first = strtotime($cut . "00");
        $elapsed = ($timestamp - $first) / $daylen;

        $weeks = 1;

        for ($i = 1; $i <= $elapsed; $i++)
        {
            $dayfind = $cut . (strlen($i) < 2 ? '0' . $i : $i);
            $daytimestamp = strtotime($dayfind);

            $day = strtolower(date("l", $daytimestamp));

            if($day == strtolower($rollover))  $weeks ++;
        }

        return $weeks;
    }

    //
    echo getWeeks("2011-06-11", "sunday"); //outputs 2, for the second week of the month
?>

Determine Week number from a date(Month) using PHP

All you need is

ceil(date('d')/7);

So your function will look like

function getWeekday($date){
  return ceil(date('d',strtotime($date))/7);
}

Demo

Even though requirement is a little strange. Week of the month is not a well defined thing but according to your comments on various answers all you need is to see week 1 if the date is within 1st 7 days of the month. 2 for next 7, 3 for next 7, 4 for next 7 and 5 for the leftovers.

Output

Old answer

Simple! you need a capital W, not a lowercase one.

W
ISO-8601 week number of year, weeks starting on Monday (added in PHP 4.1.0)

return date('W',strtotime($date));

The lowercase one - which you are using - is

Numeric representation of the day of the week

How to find week date ranges for a given month

Here is one method that loops with strtotime.

I add 86400*7 on Unix to add a week.

$month = 2;
$year = 2017;

$week = date("W", strtotime($year . "-" . $month ."-01")); // weeknumber of first day of month

Echo date("d/m/Y", strtotime($year . "-" . $month ."-01")) ." - "; // first day of month
$unix = strtotime($year."W".$week ."+1 week");
While(date("m", $unix) == $month){ // keep looping/output of while it's correct month

   Echo date("d/m/Y", $unix-86400) . "\n"; // Sunday of previous week
   Echo date("d/m/Y", $unix) ." - "; // this week's monday
   $unix = $unix + (86400*7);
}
Echo date("d/m/Y", strtotime("last day of ".$year . "-" . $month)); //echo last day of month

how to get week of month?

After some hard time looking for it, Here is the Answer, Sorry for posting a bit late here. I hope it will help you guys.

public static function getWeeksOfMonth()
{
    $currentYear = date('Y');
    $currentMonth = date('m');

    //Substitue year and month
    $time = strtotime("$currentYear-$currentMonth-01");  
    //Got the first week number
    $firstWeek = date("W", $time);

    if ($currentMonth == 12)
        $currentYear++;
    else
        $currentMonth++;

    $time = strtotime("$currentYear-$currentMonth-01") - 86400;
    $lastWeek = date("W", $time);

    $weekArr = array();

    $j = 1;
    for ($i = $firstWeek; $i <= $lastWeek; $i++) {
        $weekArr[$i] = 'week ' . $j;
        $j++;
    }
    return $weekArr;
}

The Result will be the weeks of current Month..

Array ( 
    [26] => week 1 
    [27] => week 2 
    [28] => week 3 
    [29] => week 4 
    [30] => week 5 
    [31] => week 6 
)
