Get start date and end date of current week (week

Question

I want to display start date and end date of current week. (week start=monday, week end=sunday) I manage to display monday.

But I'm unable to get sunday date. Please post me if anyone has solution.

Answer 1

Slightly Modified answer of @ReadWriteCode, this also works successfully with different months.

Date.prototype.getWeek = function()
{
    var today = new Date();
    var day = today.getDay();
    var date = today.getDate() - day;

        // Grabbing Start/End Dates
    var StartDate = new Date();
    var EndDate = new Date();
    StartDate.setHours(0,0,0,0); EndDate.setHours(0,0,0,0);
    StartDate.setDate(today.getDate()-day);
    EndDate.setDate(today.getDate()-day+6);
    return {
        startDate:StartDate,
        endDate: EndDate
    };
} 
var thisWeekDates=new Date().getWeek();

I hope this will work for you :

Date.prototype.getWeekEndDate = function () {
    diff = 6 - this.getDay();
    if (diff < 0) {
        diff += 6;
    }
    this.setDate(this.getDate() + (1 * diff));
    return this;
}
Date.prototype.getWeekStartDate = function () {
    diff = this.getDay() - 6;
    if (diff < 0) {
        diff += 7;
    }
    return this.setDate(this.getDate() + (-1 * diff));
}

These method will return start date and end date of the week.

Answer 3

SetDate will sets the day of the month. Using setDate during start and end of the month, will result in wrong week

var curr = new Date("08-Jul-2014"); // get current date
var first = curr.getDate() - curr.getDay(); // First day is the day of the month - the day of the week
var last = first + 6; // last day is the first day + 6
var firstday = new Date(curr.setDate(first)); // 06-Jul-2014
var lastday = new Date(curr.setDate(last)); // 12-Jul-2014

If setting Date is 01-Jul-2014, it will show firstday as 29-Jun-2014 and lastday as 05-Jun-2014 instead of 05-Jul-2014. So to overcome this issue I used

var curr = new Date();
day = curr.getDay();
firstday = new Date(curr.getTime() - 60*60*24* day*1000); // will return firstday (i.e. Sunday) of the week
lastday = new Date(curr.getTime() + 60 * 60 *24 * 6 * 1000); // adding (60*60*6*24*1000) means adding six days to the firstday which results in lastday (Saturday) of the week

1. Different months issues is also fixed with below code.

2. Added format "M.dd.yyyy" function.

   function startAndEndOfWeek(setDate) { var day = null; var date = null;var month = null;var year = null; var mon = null; var tue = null; var wed = null; var thu = null; var fri = null; var sat = null; var sun = null;

   var now = setDate ? new Date(setDate) : new Date();
   now.setHours(0,0,0,0);
   
   var monday = new Date(now); var tuesday = new Date(now); var wednesday = new Date(now); var thursday = new Date(now);
   var friday = new Date(now); var saturday = new Date(now); var sunday = new Date(now); 
   
   if(new Date(now).getDay() == 0)
   {
       monday.setDate(monday.getDate() - 6);
       tuesday.setDate(tuesday.getDate() - 5);
       wednesday.setDate(wednesday.getDate() - 4);
       thursday.setDate(thursday.getDate() - 3);
       friday.setDate(friday.getDate() - 2);
       saturday.setDate(saturday.getDate() - 1);
       sunday.setDate(sunday.getDate() - 0);
   }
   else
   {
       monday.setDate(monday.getDate() - monday.getDay() + 1);
       tuesday.setDate(tuesday.getDate() - tuesday.getDay() + 2);
       wednesday.setDate(wednesday.getDate() - wednesday.getDay() + 3);
       thursday.setDate(thursday.getDate() - thursday.getDay() + 4);
       friday.setDate(friday.getDate() - friday.getDay() + 5);
       saturday.setDate(saturday.getDate() - saturday.getDay() + 6);
       sunday.setDate(sunday.getDate() - sunday.getDay() + 7);
   }
   
   date = monday.getDate();
   month = monday.getMonth();
   year = monday.getFullYear();
   mon = getMonthValue(month) + "." + getDateValue(date) + "." +  year;
   
   date = tuesday.getDate();
   month = tuesday.getMonth();
   year = tuesday.getFullYear();
   tue = getMonthValue(month) + "." + getDateValue(date) + "." +  year;
   
   date = wednesday.getDate();
   month = wednesday.getMonth();
   year = wednesday.getFullYear();
   wed = getMonthValue(month) + "." + getDateValue(date) + "." +  year;
   
   date = thursday.getDate();
   month = thursday.getMonth();
   year = thursday.getFullYear();
   thu = getMonthValue(month) + "." + getDateValue(date) + "." +  year;
   
   date = friday.getDate();
   month = friday.getMonth();
   year = friday.getFullYear();
   fri = getMonthValue(month) + "." + getDateValue(date) + "." +  year;
   
   date = saturday.getDate();
   month = saturday.getMonth();
   year = saturday.getFullYear();
   sat = getMonthValue(month) + "." + getDateValue(date) + "." +  year;
   
   date = sunday.getDate();
   month = sunday.getMonth();
   year = sunday.getFullYear();
   sun = getMonthValue(month) + "." + getDateValue(date) + "." +  year;
   
   return [mon, tue , wed, thu, fri, sat, sun];
   

   }

   function getMonthValue(month) { switch(month) { case 0: return "Jan"; break; case 1: return "Feb"; break; case 2: return "Mar"; break; case 3: return "Apr"; break; case 4: return "May"; break; case 5: return "Jun"; break; case 6: return "Jul"; break; case 7: return "Aug"; break; case 8: return "Sep"; break; case 9: return "Oct"; break; case 10: return "Nov"; break; case 11: return "Dec"; break; } } function getDateValue(day) { if(parseInt(day) < 10) { return "0" + day; } return day; }

Answer 5

Try this:

var current = new Date();     // get current date    
var weekstart = current.getDate() - current.getDay() +1;    
var weekend = weekstart + 6;       // end day is the first day + 6 
var monday = new Date(current.setDate(weekstart));  
var sunday = new Date(current.setDate(weekend));

Answer 6

Using https://momentjs.com makes it more simple.

1. To get week starting with Sunday and ending with Saturday, then use: moment().startOf("week").toDate() and moment().endOf("week").toDate()

2. To get week starting with Monday and ending with Sunday, then use: moment().startOf("isoWeek").toDate() and moment().endOf("isoWeek").toDate()

Tried this on moment v2.18.1, it works.

Hope this helps, for more you can refer moment docs.
