How to check if a date is in a given range?

Having each year divided into periods such as

from 11-28 to 01-20
from 01-21 to 02-16
from 02-17 to 03-15
from 03-16 to 05-04
from 05-05 to 07-25
from 07-26 to 10-10
from 10-11 to 11-27

And some days as

$date1 = '06-09-1990';
$date2 = '05-03-1867';
$date3 = '02-29-1945';
$date4 = '06-24-2012';
$date5 = '12-25-2015';
$date6 = '07-15-2010';

How to check if a day is in one of these range?

P.S. Excuse me for my english

I think it's nota duplicate. The ranges have no "year" in this question so it's more difficult. — borazslo, Sep 13 '14 at 16:47

You can use this small function:

<?php
    $s_date = strtotime("2009-03-01 12:00");
    $e_date = strtotime("2009-03-03 14:00");
    $date = strtotime("2009-03-02 13:00");
    if($date > $s_date && $date < $e_date)
        print "Date is between start and end";
    else
        print "Date is outside start and end";
?>

Another way

function isDateBetween($dt_start, $dt_check, $dt_end){
    if(strtotime($dt_check) > strtotime($dt_start) && strtotime($dt_check) < strtotime($dt_end))
        return true;
    return false;
}
isDateBetween("2004-01-01", "2004-01-02", "2004-01-03")

i need a method valid for any year, not for a specific one – danielevigi Jun 23 '12 at 18:05
What is specific here??? – Praveen Kumar Purushothaman Jun 24 '12 at 02:21
The algorithm must be valid for the same periods but for any year. With your method I have to insert a check for each year (obviously impossible). – danielevigi Jun 24 '12 at 09:27
I don't get what you said? It is valid for all the years. What kinda check you need to insert? – Praveen Kumar Purushothaman Jun 24 '12 at 09:40
I have a certain day (e.g. 06/09/1990, 05/03/1867 etc...). I want to give this day to a period. The periods are the same for each year (e.g. from 03-15 to 04-05, from 04-06 to 04-20 etc. ...). – danielevigi Jun 24 '12 at 09:58
Oh okay, in that case, you can hardcode it in the function itself right? Just give `$dt_start = '06/09/1990'` and don't give the start and end dates. Or which ever you wanna omit. – Praveen Kumar Purushothaman Jun 24 '12 at 10:28

Date values in PHP are expressed as UNIX timestamps and they represent the number of seconds passed since January 1st 1970.

You can use mktime function to create the dates ( http://php.net/manual/en/function.mktime.php ). Once you have them as numbers, you can easily compare them.

$interval_start = mktime(0, 0, 0, 1, 0, 2000);
$interval_end = mktime(0, 0, 0, 1, 0, 2010);
$my_date = mktime(0, 0, 0, 1, 0, 2004);
if($my_date > $interval_start && $my_date < $interval_end) {
    // in the interval
} else {
    // not in the interval
}

i need a method valid for any year, not for a specific one – danielevigi Jun 23 '12 at 18:06 — danielevigi, Jun 23 '12 at 18:06
