Calculate the days of the week from Monday to Saturday

In my form, I have a data field where I select the day of the week! For example, if I select today 23-03-2012 Friday, I need to get a few days from the previous Monday to the next Saturday.

array:

[0],[19-03-2012],[Monday]
[1],[20-03-2012],[Monday]
[2],[21-03-2012],[Wednesday]
[3],[22-03-2012],[Monday]
[4],[23-03-2012],[Friday]
[5],[24-03-2012],[Saturday]

How can I do this on any given day of the week, explicitly noting the changes? Thanks to

This function will return an array of all dates in the week date

from Monday to Saturday.



function GetDaysOfWeek(date)
{
    var days = new Array();
    for (var i = 0; i < 6; i++)
    {
        days[i] = new Date(date.getYear(),
                           date.getMonth(),
                           date.getDate() - date.getDay() + 1 + i);
    }
    return days;
}

might try MomentJs: http://momentjs.com/docs/

a few examples:



moment().day(-7); // set to last Sunday (0 - 7) 
moment().day(7); // set to next Sunday (0 + 7)
moment().day(10); // set to next Wednesday (3 + 7)
moment().day(24); // set to 3 Wednesdays from now (3 + 7 + 7 + 7)

To display the current day of the week:

 var now = new Date();
 var dayNames = ["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"];
 document.write("Today is " + dayNames[now.getDay()] + ".");

  • First, find today's date.
  • Find the last Monday (including today)
  • Show this date and the next 5 days after it (Tuesday-Saturday)
var d = new Date();

if (d.getDay()==0){
   d.setDate(d.getDate() + 1);
}

​while (d.getDay() != 1){
    d.setDate(d.getDate() - 1);
}

var days = new Array();

for (var i = 0; i < 6; i++){
  days[i] = d.getDate() + i;
}

return days;

try this:

var dayString = ["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"];

var now = new Date();
var currentDay = now.getDay(); // return 0 for Sunday, 6 for Saturday
var result = [];
var tempDate = new Date(now.getTime());
tempDate.setDate(now.getDate()-(currentDay+6)%7); // now tempDate is previous Monday
while(tempDate.getDay()!=0) {
    var currentMonth = tempDate.getMonth()+1;
    if(currentMonth<10) currentMonth = "0"+currentMonth;
    result.push([tempDate.getDay()-1,tempDate.getDate()+"-"+currentMonth+"-"+tempDate.getFullYear(),dayString[tempDate.getDay()]]);
    tempDate.setDate(tempDate.getDate()+1);
}
console.log(result);

Something like the following will do the trick, I'm sure you can get the formatting to wherever you want.

// Assuming d is a date object
function getDateArray(din) {

  // Add leading zero to one digit numbers
  function aZ(n){return (n<10? '0':'') + n;}

  var days = ['Sunday','Monday','Tuesday','Wednesday',
              'Thursday','Friday','Saturday'];
  var d = new Date(din); // Don't wreck input date  
  var dn = d.getDay();
  var a = [];
  var i = 6; // length of day array

  if (!dn) {
    // It Sunday, what now? 
    return ['Sunday!'];
  }

  d.setDate(d.getDate() + 6 - dn); // Next Saturday

  do {
    a[i--] = i + ' ' + aZ(d.getDate()) +
             '-' + aZ(d.getMonth() + 1) +
             '-' + d.getFullYear() + 
             ' ' + days[d.getDay()];     
    d.setDate(d.getDate() - 1);
  } while (i);

  return a;
}

// Test it
var date = new Date(2012,2,2)

alert( date + '\n\n' + getDateArray(date).join('\n'));
