[javascript] Check if one date is between two dates

I need to check if a date - a string in dd/mm/yyyy format - falls between two other dates having the same format dd/mm/yyyy

I tried this, but it doesn't work:

var dateFrom = "02/05/2013";
var dateTo = "02/09/2013";
var dateCheck = "02/07/2013";

var from = Date.parse(dateFrom);
var to   = Date.parse(dateTo);
var check = Date.parse(dateCheck );

if((check <= to && check >= from))      
    alert("date contained");

I used debugger and checked, the to and from variables have isNaN value. Could you help me?

Instead of comparing the dates directly, compare the getTime() value of the date. The getTime() function returns the number of milliseconds since Jan 1, 1970 as an integer-- should be trivial to determine if one integer falls between two other integers.

Something like

if((check.getTime() <= to.getTime() && check.getTime() >= from.getTime()))      alert("date contained");

Try this:

HTML

<div id="eventCheck"></div>

JAVASCRIPT

// ----------------------------------------------------//
// Todays date
var today = new Date();
var dd = today.getDate();
var mm = today.getMonth()+1; //January is 0!
var yyyy = today.getFullYear();

// Add Zero if it number is between 0-9
if(dd<10) {
    dd = '0'+dd;
}
if(mm<10) {
    mm = '0'+mm;
}

var today = yyyy + '' + mm + '' + dd ;


// ----------------------------------------------------//
// Day of event
var endDay = 15; // day 15
var endMonth = 01; // month 01 (January)
var endYear = 2017; // year 2017

// Add Zero if it number is between 0-9
if(endDay<10) {
    endDay = '0'+endDay;
} 
if(endMonth<10) {
    endMonth = '0'+endMonth;
}

// eventDay - date of the event
var eventDay = endYear + '/' + endMonth + '/' + endDay;
// ----------------------------------------------------//



// ----------------------------------------------------//
// check if eventDay has been or not
if ( eventDay < today ) {
    document.getElementById('eventCheck').innerHTML += 'Date has passed (event is over)';  // true
} else {
    document.getElementById('eventCheck').innerHTML += 'Date has not passed (upcoming event)'; // false
}

The answer that has 50 votes doesn't check for date in only checks for months. That answer is not correct. The code below works.

var dateFrom = "01/08/2017";
var dateTo = "01/10/2017";
var dateCheck = "05/09/2017";

var d1 = dateFrom.split("/");
var d2 = dateTo.split("/");
var c = dateCheck.split("/");

var from = new Date(d1);  // -1 because months are from 0 to 11
var to   = new Date(d2);
var check = new Date(c);

alert(check > from && check < to);

This is the code posted in another answer and I have changed the dates and that's how I noticed it doesn't work

var dateFrom = "02/05/2013";
var dateTo = "02/09/2013";
var dateCheck = "07/07/2013";

var d1 = dateFrom.split("/");
var d2 = dateTo.split("/");
var c = dateCheck.split("/");

var from = new Date(d1[2], parseInt(d1[1])-1, d1[0]);  // -1 because months are from 0 to 11
var to   = new Date(d2[2], parseInt(d2[1])-1, d2[0]);
var check = new Date(c[2], parseInt(c[1])-1, c[0]);


alert(check > from && check < to);

Try what's below. It will help you...

Fiddle : http://jsfiddle.net/RYh7U/146/

Script :

if(dateCheck("02/05/2013","02/09/2013","02/07/2013"))
    alert("Availed");
else
    alert("Not Availed");

function dateCheck(from,to,check) {

    var fDate,lDate,cDate;
    fDate = Date.parse(from);
    lDate = Date.parse(to);
    cDate = Date.parse(check);

    if((cDate <= lDate && cDate >= fDate)) {
        return true;
    }
    return false;
}

I have created customize function to validate given date is between two dates or not.

var getvalidDate = function(d){ return new Date(d) }

function validateDateBetweenTwoDates(fromDate,toDate,givenDate){
    return getvalidDate(givenDate) <= getvalidDate(toDate) && getvalidDate(givenDate) >= getvalidDate(fromDate);
}

Suppose for example your date is coming like this & you need to install momentjs for advance date features.

let cmpDate = Thu Aug 27 2020 00:00:00 GMT+0530 (India Standard Time)

    let format = "MM/DD/YYYY";
    let startDate: any = moment().format(format);
    let endDate: any = moment().add(30, "days").format(format);
    let compareDate: any = moment(cmpDate).format(format);
    var startDate1 = startDate.split("/");
    var startDate2 = endDate.split("/");
    var compareDate1 = compareDate.split("/");

    var fromDate = new Date(startDate1[2], parseInt(startDate1[1]) - 1, startDate1[0]);
    var toDate = new Date(startDate2[2], parseInt(startDate2[1]) - 1, startDate2[0]);
    var checkDate = new Date(compareDate1[2], parseInt(compareDate1[1]) - 1, compareDate1[0]);

    if (checkDate > fromDate && checkDate < toDate) {
      ... condition works between current date to next 30 days
    }

I did the same thing that @Diode, the first answer, but i made the condition with a range of dates, i hope this example going to be useful for someone

e.g (the same code to example with array of dates)

var dateFrom = "02/06/2013";_x000D_
var dateTo = "02/09/2013";_x000D_
_x000D_
var d1 = dateFrom.split("/");_x000D_
var d2 = dateTo.split("/");_x000D_
_x000D_
var from = new Date(d1[2], parseInt(d1[1])-1, d1[0]);  // -1 because months are from 0 to 11_x000D_
var to   = new Date(d2[2], parseInt(d2[1])-1, d2[0]); _x000D_
_x000D_
_x000D_
_x000D_
var dates= ["02/06/2013", "02/07/2013", "02/08/2013", "02/09/2013", "02/07/2013", "02/10/2013", "02/011/2013"];_x000D_
_x000D_
dates.forEach(element => {_x000D_
   let parts = element.split("/");_x000D_
   let date= new Date(parts[2], parseInt(parts[1]) - 1, parts[0]);_x000D_
        if (date >= from && date < to) {_x000D_
           console.log('dates in range', date);_x000D_
        }_x000D_
})

Try this

var gdate='01-05-2014';
        date =Date.parse(gdate.split('-')[1]+'-'+gdate.split('-')[0]+'-'+gdate.split('-')[2]);
        if(parseInt(date) < parseInt(Date.now()))
        {
            alert('small');
        }else{
            alert('big');
        }

Simplified way of doing this based on the accepted answer.

In my case I needed to check if current date (Today) is pithing the range of two other dates so used newDate() instead of hardcoded values but you can get the point how you can use hardcoded dates.

var currentDate = new Date().toJSON().slice(0,10);
var from = new Date('2020/01/01');
var to   = new Date('2020/01/31');
var check = new Date(currentDate);

console.log(check > from && check < to);

Here is a Date Prototype method written in typescript:

Date.prototype.isBetween = isBetween;
interface Date { isBetween: typeof isBetween }
function isBetween(minDate: Date, maxDate: Date): boolean {
  if (!this.getTime) throw new Error('isBetween() was called on a non Date object');
  return !minDate ? true : this.getTime() >= minDate.getTime()
    && !maxDate ? true : this.getTime() <= maxDate.getTime();
};
