I need to know the percentage remaining between two dates.
I've used this code:
$(function () {
var end = $('#data').text();
var formattedDate = new Date();
var day = formattedDate.getDate();
var month = formattedDate.getMonth();
month += 1;
var year = formattedDate.getFullYear();
if (day < 10) {
day = "0" + day;
}
if (month < 10) {
month = "0" + month;
}
var today = day + "/" + month + "/" + year;
remaining = Math.round(((end - today) * 100) / today));
alert(remaining);
});
But it does'nt work.
Any suggestion?
Thanks
You're subtracting two strings, which is why it won't work.
Subtract two Date objects instead, and you'll get the milliseconds between them (ignoring the maths as to what you define as a % of 2 dates).
var now = new Date();
var then = new Date($('#data').text());
var remaining = Math.round(((then - now) * 100) / now);
You can still, of course, get your formatted string of DD/MM/YY via;
var formattedDays = (now.getDay() < 10 ? "0" : "") + now.getDay();
var formattedMonth = (now.getMonth() < 9 ? "0" : "") + (now.getMonth() + 1);
var formattedDate = formattedDays + "/" + formattedMonth + "/" + now.getFullYear();
Note that you have an extra closing parenthesis at the end of your Math.round() line as well.

I would like to convert the below time to CST. How can I achieve it using Jquery or Javascript? It should always display as a CST timezone.
var date = new Date();
var dd = date.getDate();
var mm = date.getMonth() + 1;
var yy = date.getFullYear();
var hh = date.getHours();
var minutes = date.getMinutes();
if (minutes < 10)
minutes = "0" + minutes;
var suffix = "AM";
if (hh >= 12) {
suffix = "PM";
hh = hh - 12;
}
if (hh == 0) {
hh = 12;
}
if (dd < 10) {
dd = '0' + dd;
}
if (mm < 10) {
mm = '0' + mm;
}
var valsss = (mm) + "/" + dd + "/" + yy + hh + " " + ":" + minutes + " " + suffix;
$("#printDate").text(valsss);
<p id= "#printDate"></p>
Please check this below like can convert
d = new Date();
localTime = d.getTime();
localOffset = d.getTimezoneOffset() * 60000;
utc = localTime + localOffset;
offset = -5;
cst = utc + (3600000 * offset);
nd = new Date(cst);
newdate = (nd.toLocaleString());
$('#printDate').text(newdate + ' CST');
You have to consider that the browser will change the displayed date to the user's timezone. I wrote this to grab a date in a kendo grid by a class on a td and set it to CST. In this case the server is in CST and I wanted the time say 12:00 to display as 12:00 for a user in MST not as 11:00 in MST. Hope it helps...
Checks User / Browser's timezone offset.
Get difference in hours from server timezone offset.
Looks at a column on the Kendo Grid with class .dbDate.
Grabs the grid date (displayedTime).
Uses Moment.js to Convert (convertedTime) it based on the difference (diff)
in hours we pass it.
Formats convertedTime to the desired format i.e. 02/08/18 23:57.
Passes the Grid back the updated date and time.
Must Run Last on load.
function dateOffset() {
var date = new Date();
var offset;
var diff;
offset = date.getTimezoneOffset()
if (offset > 360) { //360 = CST
diff = +(offset - 360) / 60
} else if (offset < 360) {
diff = -(360 - offset) / 60
} else {
diff = 0
}
$(".dbDate").each(function (i) {
var grid = $('#Grid').data('kendoGrid');
var displayedTime = grid.dataSource.data()[i].TicketDateTime
var convertedTime = new moment(displayedTime).add(diff, 'hours').toDate();
var originalTime = moment(convertedTime).format("MM/DD/YY HH:mm");
i + 1
$(this).html(originalTime)
})
}
I have a datetime value gotten from an SQLServer database table:
2016-08-16T17:00:00Z
Using javascript, I want to format the date as follow:
16/08/2016 17:00:00
I have used the code below:
$scope.FormatDate = function (value) {
if (value !== null && typeof (value) !== 'undefined') {
var date = new Date(value);
var returnStr = date.getDate() + "/" + date.getMonth() + 1 + "/" + date.getFullYear();
return returnStr;
} else {
return value;
}
}
The result from the sample resource is:
17/71/2016
I want your help to get the output result as: "16/08/2016 17:00:00"
If all you want to do is format it then you don't need to create an actual date object, you can do a simple string replace using a regex to grab the individual parts, as per this simple demo:
var value = "2016-08-16T17:00:00Z";
console.log(value.replace(/(\d{4})-(\d\d)-(\d\d)T([^Z]+)Z/,"$3/$2/$1 $4"));
In the context of your function:
$scope.FormatDate = function (value) {
if (value !== null && typeof (value) !== 'undefined') {
return value.replace(/(\d{4})-(\d\d)-(\d\d)T([^Z]+)Z/,"$3/$2/$1 $4");
} else {
return value;
}
}
Another solution:
var parsed = Date.parse("2016-08-16T17:00:00Z"),
date = new Date(parsed),
day = date.getUTCDate(),
month = date.getUTCMonth() + 1,
year = date.getUTCFullYear(),
hour = date.getUTCHours(),
minute = date.getUTCMinutes(),
second = date.getUTCSeconds(),
dateStr = "";
day = day < 10 ? "0" + day : day;
month = month < 10 ? "0" + month : month;
hour = hour < 10 ? "0" + hour : hour;
minute = minute < 10 ? "0" + minute : minute;
second = second < 10 ? "0" + second : second;
dateStr = day + "/" + month + "/" + year + " " + hour + ":" + minute + ":" + second;
console.log(dateStr);
Updated: The old code may change across countries, because they have different local date/time format, so I have updated to format it explicitly.
Try this
function formatDate(date)
{
var hours = date.getHours();
var minutes = date.getMinutes();
var seconds = date.getSeconds();
minutes = minutes < 10 ? '0'+minutes : minutes;
seconds = seconds < 10 ? '0'+seconds : seconds;
var strTime = hours + ':' + minutes + ':' +seconds ;
return date.getMonth()+1 + "/" + date.getDate() + "/" + date.getFullYear() + " " + strTime;
}
You can use this library to format the date as you desire with implementing some logic.
http://momentjs.com/
Just work with the function parameter value and use moment.
Example:
const date = moment("2016-08-16T17:00:00Z").date();
const month = moment("2016-08-16T17:00:00Z").month();
const hour = moment("2016-08-16T17:00:00Z").hour();
const year = moment("2016-08-16T17:00:00Z").year();
const minute = moment("2016-08-16T17:00:00Z").minute();
const sec = moment("2016-08-16T17:00:00Z").second();
// implementing some logic
console.log('' + date + '/' + month + '/' + year + ' ' + hour + ':' + minute + ':' + sec);

"2015-06-23 14:00:00"
I tried to format above date time into 12 hour base but stuck in somewhere.
function formatDate(raw_date){
var right = raw_date.substring(10, 0);
var hours = ((right[0].substring(2,0) + 11) % 12 + 1);
var min = raw_date.substring(14,16);
var suffix = right[1] >= 12 ? "PM":"AM";
right[1] = ((right[1] + 11) % 12 + 1) + suffix;
return hours + ':' + min + ' ' + suffix;
}
Can someone help? My desired output is "23/06/2015 02:00 PM"
Try this:
function formatDate(raw_date) {
var right = new Date(raw_date);
var currentHours = right.getHours();
var timeOfDay = (currentHours < 12) ? "AM" : "PM";
if (currentHours > 12) {
currentHours -= 12;
}
return (right.getDate() + '/' + right.getMonth()+ '/' + right.getFullYear() +" "+ currentHours+ ":"+right.getMinutes() + timeOfDay);
}
alert(formatDate("2015-06-23 14:00:00"));
Demo
Solution based on your code:
function formatDate(raw_date){
var year = raw_date.substring(0,4);
var month = raw_date.substring(5,7);
var day = raw_date.substring(8,10);
var right = raw_date.substring(10);
var hours = ((right.substring(0,3))% 12 );
var min = raw_date.substring(14,16);
var suffix = right.substring(0,3) >= 12 ? "PM":"AM";
return day + "/"+month+"/"+year+" "+hours + ':' + min + ' ' + suffix;
}
You should follow a simple flow.
Try to break down the input -> convert them _> and then sum them up:
function formatDate(raw_date){
var right = raw_date.substring(0, 10);
var year=right.substring(0,4);
var month=right.substring(5,7);
var day=right.substring(8,10);
right=day+"/"+month+"/"+year;
var left=raw_date.substring(11, raw_date.length);
var hours = left.substring(0,2);
var suffix = hours >= 12 ? "PM":"AM";
hours=hours-12;
if(hours<10) hours='0'+hours;
var min = left.substring(3,5);
left=hours+":"+min+" "+suffix;
return right + ' ' + left;
}
Im creating a JS clock/date. I previously got the time to work perfectly then I decided to add more onto my clock (date). Right now I cant figure why it isn't working. If anyone could give me tip or idea how to fix it, I would greatly appreciate it.
function timedate()
{
var currentTime = new Date();
var hours = currentTime.getHours();
var minutes = currentTime.getMinutes();
var dn="PM"
var d = currentTime.getDate(); <--
var day = (d < 10) ? '0' + d : d;
var m = currentTime.getMonth() + 1; <--
var month = (m < 10) ? '0' + m : m;
var yy = currentTime.getYear(); <--
var year = (yy < 1000) ? yy + 1900 : yy;
if (hours<12)
{
dn="AM"
}
if (hours>12)
{
hours=hours-12
}
if (hours==0)
{
hours=12
}
if (minutes<=9)
{
minutes="0"+minutes
}
var clocklocation = document.getElementById('timedate');
clocklocation.innerHTML = "" +hours+":"+minutes+dn+""+day + "/" + month + "/" + year;
setTimeout("timedate()", 1000);
}
timedate();
Your code works, it is just not visible because you do not have seconds showing
Also change
setTimeout("timedate()", 1000);
to
setTimeout(timedate, 1000);
because it is not recommended
and remove the <--
Make sure it runs onload or after the tag you want to show it in
Alternatively remove the line and change
timedate();
to
setInterval(timedate,1000)
const pad = num => ("0" + num).slice(-2);
const timedate = () => {
const currentTime = new Date();
let hours = currentTime.getHours();
const minutes = pad(currentTime.getMinutes());
const seconds = pad(currentTime.getSeconds());
const d = currentTime.getDate();
const day = pad(d);
const month = pad(currentTime.getMonth() + 1);
const yy = currentTime.getFullYear();
let dn = "PM"
if (hours <= 12) dn = "AM";
if (hours >= 12) hours -= 12;
if (hours == 0) hours = 12;
hours = pad(hours);
document.getElementById('timedate').innerHTML = "" +
hours + ":" +
minutes + ":" +
seconds + dn + " " +
day + "/" + month + "/" + yy;
}
window.addEventListener("load", function() {
setInterval(timedate, 1000);
});
<span id="timedate"></span>
If you set the timeout with setTimeout(timedate, 1000) instead of your current magic string version, it works1.
1 I took the liberty of adding seconds to your code as well, to make it obvious that the clock updates. Of course, you also need to remove <-- from your code.
What's wrong with this script?
When I set my clock to say 29/04/2011 it adds 36/4/2011 in the week input! but the correct date should be 6/5/2011
var d = new Date();
var curr_date = d.getDate();
var tomo_date = d.getDate()+1;
var seven_date = d.getDate()+7;
var curr_month = d.getMonth();
curr_month++;
var curr_year = d.getFullYear();
var tomorrowsDate =(tomo_date + "/" + curr_month + "/" + curr_year);
var weekDate =(seven_date + "/" + curr_month + "/" + curr_year);
{
jQuery("input[id*='tomorrow']").val(tomorrowsDate);
jQuery("input[id*='week']").val(weekDate);
}
var date = new Date();
date.setDate(date.getDate() + 7);
console.log(date);
And yes, this also works if date.getDate() + 7 is greater than the last day of the month. See MDN for more information.
Without declaration
To return timestamp
new Date().setDate(new Date().getDate() + 7)
To return date
new Date(new Date().setDate(new Date().getDate() + 7))
Something like this?
var days = 7;
var date = new Date();
var res = date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
alert(res);
convert to date again:
date = new Date(res);
alert(date)
or alternatively:
date = new Date(res);
// hours part from the timestamp
var hours = date.getHours();
// minutes part from the timestamp
var minutes = date.getMinutes();
// seconds part from the timestamp
var seconds = date.getSeconds();
// will display time in 10:30:23 format
var formattedTime = date + '-' + hours + ':' + minutes + ':' + seconds;
alert(formattedTime)
In One line:
new Date(Date.now() + 7 * 24 * 60 * 60 * 1000)
The simple way to get a date x days in the future is to increment the date:
function addDays(dateObj, numDays) {
return dateObj.setDate(dateObj.getDate() + numDays);
}
Note that this modifies the supplied date object, e.g.
function addDays(dateObj, numDays) {
dateObj.setDate(dateObj.getDate() + numDays);
return dateObj;
}
var now = new Date();
var tomorrow = addDays(new Date(), 1);
var nextWeek = addDays(new Date(), 7);
alert(
'Today: ' + now +
'\nTomorrow: ' + tomorrow +
'\nNext week: ' + nextWeek
);
Using the Date object's methods will could come in handy.
e.g.:
myDate = new Date();
plusSeven = new Date(myDate.setDate(myDate.getDate() + 7));
var days = 7;
var date = new Date();
var res = date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
var d = new Date(res);
var month = d.getMonth() + 1;
var day = d.getDate();
var output = d.getFullYear() + '/' +
(month < 10 ? '0' : '') + month + '/' +
(day < 10 ? '0' : '') + day;
$('#txtEndDate').val(output);
var future = new Date(); // get today date
future.setDate(future.getDate() + 7); // add 7 days
var finalDate = future.getFullYear() +'-'+ ((future.getMonth() + 1) < 10 ? '0' : '') + (future.getMonth() + 1) +'-'+ future.getDate();
console.log(finalDate);
You can add or increase the day of week for the following example and hope this will helpful for you.Lets see....
//Current date
var currentDate = new Date();
//to set Bangladeshi date need to add hour 6
currentDate.setUTCHours(6);
//here 2 is day increament for the date and you can use -2 for decreament day
currentDate.setDate(currentDate.getDate() +parseInt(2));
//formatting date by mm/dd/yyyy
var dateInmmddyyyy = currentDate.getMonth() + 1 + '/' + currentDate.getDate() + '/' + currentDate.getFullYear();
Two problems here:
seven_date is a number, not a date. 29 + 7 = 36
getMonth returns a zero based index of the month. So adding one just gets you the current month number.
