Okay I have the following problem. I want to get the current dateTime and then want do check if a date that I enter is bigger than the current DateTime. The format of my dateTime should look like this.
03/11/2012 09:37 AM
Here is the function how I get the current DateTime.
function getCurrentDateTime()
{
var currentTime = new Date()
// Date
var month = currentTime.getMonth() + 1;
if (month < 10){
month = "0" + month;
}
var day = currentTime.getDate();
var year = currentTime.getFullYear();
// Time
var hours = currentTime.getHours();
var minutes = currentTime.getMinutes();
if (minutes < 10){
minutes = "0" + minutes;
}
if(hours > 11){
var dateString = month + "/" + day + "/" + year + " " + hours + ":" + minutes + " " + "PM";
test = new Date(dateString);
return dateString ;
} else {
var dateString = month + "/" + day + "/" + year + " " + hours + ":" + minutes + " " + "AM";
return dateString;
}
}
As you can see how it gives back a string. But when I want to covert it to a date with this function. I get this format Fri May 11 2012 09:37:00 GMT+0200 (Romance Daylight Time)
date = new Date(dateString);
And with this I can't calculate.
Could anybody help me how I can get the current date in this format so that I can do the check?
Kind regards.
Javascript provides very limited functionality for working with dates out of the box. Use an external library like momentjs.
For example, your function would be reduced to
var stringDate = moment().format("DD/MM/YYYY HH:mm A");
And you could convert that and compare it to the current time with
var earlierDate = moment(stringDate, "DD/MM/YYYY HH:mm A");
if (earlierDate.valueOf() < moment().valueOf()) {
// earlier indeed
}
datejs is another lib for solving date-manipulation problems

In BIRT, i have a column containing a datetime stored as a string. I need to convert these string to datetime format and put the result in another column using Javascript.
The string is the form of: for example: Fri 21 Feb 2014, 09:40 AM.
Hence this when converted to a datetime format and exported to excel, the column should be treat as a date.
Can any one of you help me to do it?
Cheers,
Other answers do not take into consideration this question is in a BIRT context.
Create a computed column in your dataset, with "Date time" as datatype
Enter as expression:
new Date(row["myDateStringField"]);
Where "myDateStringField" is your DateTime column in a String format. Then use this computed column in your report instead of the String column.
That's it!
Checkout momentjs!
You can parse your time of any format like
moment("12-25-1995", "MM-DD-YYYY");
In your case, you don't even have to specify the format. It automatically recognizes it.
And you can output ISO format or convert it to a Javascript Date object.
This is extremely easy to do with javascript. The following code will make a date in a format that Excel will recognize as a date.
http://jsfiddle.net/bbankes/d7SwQ/
var dateString = 'Fri 21 Feb 2014, 09:40 AM';
var date = new Date(dateString);
var yr = date.getFullYear();
var mo = date.getMonth() + 1;
var day = date.getDate();
var hours = date.getHours();
var hr = hours < 10 ? '0' + hours : hours;
var minutes = date.getMinutes();
var min = (minutes < 10) ? '0' + minutes : minutes;
var seconds = date.getSeconds();
var sec = (seconds < 10) ? '0' + seconds : seconds;
var newDateString = yr + '-' + mo + '-' + day;
var newTimeString = hr + ':' + min + ':' + sec;
var excelDateString = newDateString + ' ' + newTimeString;
If you just want to reformat 'Fri 21 Feb 2014, 09:04 AM' as '2014-02-21 09:04', then the following will do:
function stringToTimestamp(s) {
var t = s.match(/[\d\w]+/g);
var months = {jan:'01',feb:'02',mar:'03',apr:'04',may:'05',jun:'06',
jul:'07',aug:'08',sep:'09',oct:'10',nov:'11',dec:'12'};
function pad(n){return (n<10?'0':'') + +n;}
var hrs = t[4] % 12;
hrs += /pm$/i.test(t[6])? 12 : 0;
return t[3] + '-' + months[t[2].toLowerCase()] + '-' + pad(t[1]) + ' ' +
pad(hrs) + ':' + pad(t[5]);
}
console.log(stringToTimestamp('Fri 21 Feb 2014, 09:04 AM')); // 2014-02-21 09:04
use the ISO format: YYYY-MM-DDTHH:MM:SS or YYYY-MM-DD
new Date('2011-04-11T11:51:00');
or
new Date('2011-04-11');
I am trying to convert javascript date to c# datetime
JavaScript Code
var date = new Date();
var day = date.getDay();
var month = date.getMonth();
var year = date.getFullYear();
var hour = date.getHours();
var minute = date.getMinutes();
var second = date.getSeconds();
// After this construct a string with the above results as below
var JSDateString = year+ "-" + month + "-" + day + " " + hour + ':' + minute + ':' + second;
C# Code
var JSDateString = "2016-04-02 17:15:45"; // I receive date string via Ajax call in this format
var dt = DateTime.ParseExact(JSDateString , "yyyy-mm-dd HH:mm:ss", CultureInfo.InvariantCulture);
I get invalid datetime format exception. I researched other options in internet but I didn't find any specific answer on how to convert JavaScript datetime to C# datetime.
mm is for minutes, you want MM for month:
var dt = DateTime.ParseExact(JSDateString , "yyyy-MM-dd HH:mm:ss", CultureInfo.InvariantCulture);
This might help with the JavaScript side:
function getDate() {
var date = new Date(),
year = date.getFullYear(),
month = (date.getMonth() + 1).toString(),
formatedMonth = (month.length === 1) ? ("0" + month) : month,
day = date.getDate().toString(),
formatedDay = (day.length === 1) ? ("0" + day) : day,
hour = date.getHours().toString(),
formatedHour = (hour.length === 1) ? ("0" + hour) : hour,
minute = date.getMinutes().toString(),
formatedMinute = (minute.length === 1) ? ("0" + minute) : minute,
second = date.getSeconds().toString(),
formatedSecond = (second.length === 1) ? ("0" + second) : second;
return year + "-" + formatedMonth + "-" + formatedDay + " " + formatedHour + ':' + formatedMinute + ':' + formatedSecond;
};

I had too do something like this when I building an application due to not being allowed to add thrid party JS and needing support back to IE8.
As you can see on the MSDN, mm is for minutes (00 - 59) whereas MM is for the month (01 - 12).
var JSDateString = "2016-04-02 17:15:45";
var formatCode = "yyyy-MM-dd HH:mm:ss";
var dt = DateTime.ParseExact(JSDateString , formatCode, CultureInfo.InvariantCulture);
You can see that mm is for minutes because you already use it in your HH:mm:ss.
In my program i need to alert current date with time in specific format(2015-11-18 12:23:00) so i am write like this
var date = new Date();
alert(date);
but the result is Wed Nov 18 2015 12:24:28 GMT+0530 (India Standard Time).
and also i am try like this
<script>
var d = new Date();
var c = new Date();
alert(formatDate(c));
alert(formatDate(d));
function formatDate(d)
{
var month = d.getMonth();
var day = d.getDate();
var hours = d.getHours();
var minutes = d.getMinutes();
month = month + 1;
month = month + "";
if (month.length == 1)
{
month = "0" + month;
}
day = day + "";
if (day.length == 1)
{
day = "0" + day;
}
hour = hour + "";
if (hour.length == 1)
{
hour = "0" + hour;
}
minute = minute + "";
if (minute.length == 1)
{
minute = "0" + minute;
}
return d.getFullYear()+month + '' + day + ''+ hour + '' + minute + '';
}</script>
it is also not working properly.
how can i do this in javascript and also i need to passed the veriable to database in another php file. please help me how can i do this
I think this below code are helpful us.
function getDateTimeFormate () {
now = new Date();
year = "" + now.getFullYear();
month = "" + (now.getMonth() + 1); if (month.length == 1) { month = "0" + month; }
day = "" + now.getDate(); if (day.length == 1) { day = "0" + day; }
hour = "" + now.getHours(); if (hour.length == 1) { hour = "0" + hour; }
minute = "" + now.getMinutes(); if (minute.length == 1) { minute = "0" + minute; }
second = "" + now.getSeconds(); if (second.length == 1) { second = "0" + second; }
return year + "-" + month + "-" + day + " " + hour + ":" + minute + ":" + second;
}
To get date time formate like.
alert(getDateTimeFormate());
// example alert message: 2011-05-18 15:20:12
Try this..
<script>
var currentdate = new Date();
var datetime = currentdate.getFullYear() + "-"
+ (currentdate.getMonth()+1) + "-"
+ currentdate.getDate() + " "
+ currentdate.getHours() + ":"
+ currentdate.getMinutes() + ":"
+ currentdate.getSeconds();
alert(datetime);
</script>
Output:2015-11-18 12:46:52
Demo:http://js.do/code/73749
Please try the following code:
Number.prototype.padLeft = function(base,chr){
var len = (String(base || 10).length - String(this).length)+1;
return len > 0? new Array(len).join(chr || '0')+this : this;
}
var d = new Date;
function formatDate(d){
dformat = [ (d.getMonth()+1).padLeft(),
d.getDate().padLeft(),
d.getFullYear()].join('-')+
' ' +
[ d.getHours().padLeft(),
d.getMinutes().padLeft(),
d.getSeconds().padLeft()].join(':');
return dformat;
}
alert(formatDate(d));
It will return : 11-18-2015 12:17:02. And to pass the value to a php code check this: How to pass JavaScript variables to PHP?
This might be useful
Date.prototype.yyyy = function() {
var yy = this.getFullYear().toString();
var mm = (this.getMonth()+1).toString();
var dd = this.getDate().toString();
var hh = this.getHours().toString();
var min = this.getMinutes().toString();
var ss = this.getSeconds().toString();
return yy +"-" +(mm[1]?mm:"0"+mm[0]) + "-" +(dd[1]?dd:"0"+dd[0])+" "+(hh[1]?hh:"0"+hh[0])+":"+(min[1]?min:"0"+min[0])+":"+(ss[1]?ss:"0"+ss[0]);
};
d = new Date();
d.yyyy();
From the below function you will get all the details you want to show use it according to your need
getMonth() - Returns a zero-based integer (0-11) representing the month of the year.
getDate() - Returns the day of the month (1-31).
getDay() - Returns the day of the week (0-6). 0 is Sunday, 6 is Saturday.
getHours() - Returns the hour of the day (0-23).
getMinutes() - Returns the minute (0-59).
getSeconds() - Returns the second (0-59).
getMilliseconds() - Returns the milliseconds (0-999).
getTimezoneOffset() - Returns the number of minutes between the machine local time and UTC.
var today = new Date();
var dd = today.getDate();
var mm = today.getMonth()+1; //January is 0!
var yyyy = today.getFullYear();
if(dd<10){
dd='0'+dd
}
if(mm<10){
mm='0'+mm
}
var today = dd+'/'+mm+'/'+yyyy;
document.getElementById("DATE").value = today;
Use this code:
var sec = d.getSeconds();
return d.getFullYear()+'-'+month + '-' + day + ' '+ hour + ':' + minute + ':'+sec;
instead of:
return d.getFullYear()+month + '' + day + ''+ hour + '' + minute + '';
function formatDate(dt) {
//var date = new Date(dt);
var date = new Date('2015-08-27 16:00:00'); alert(date.getMonth());
var hours = date.getHours();
var minutes = date.getMinutes();
var seconds = date.getSeconds();
var ampm = hours >= 12 ? 'pm' : 'am';
hours = hours % 12;
hours = hours ? hours : 12; // the hour '0' should be '12'
minutes = minutes < 10 ? '0' + minutes : minutes;
var strTime = hours + ':' + minutes + ':' + seconds + ' ' + ampm;
return date.getDate() + " " + date.getMonth() + " " + date.getFullYear() + " " + strTime;
}
I have tried to fetch Date and time. But I am getting NaN while alert date.getMonth();.
If I am removing time then this is working fine. But My date-time format dynamic. This is coming from the database like 0000-00-00 00:00:00.
I want to view my database date and time in the 27 Aug 2015 04:00:00 am/pm format.
The date format you are using (2015-08-27 16:00:00) is not the proper format for Firefox, though it works in Chrome. So, for this code to work properly on all browsers, it should not be used.
The below code works in Firefox and Chrome:
I've replaced the string variable date - with /. This format works for both Firefox and Chrome.
Another format that works in Firefox and Chrome is 1995-12-17T03:24:00 which includes T instead of ' ' (space).
However, the above format gives different value in Chrome and Firefox.
new Date('2015-10-05T03:24:00'); // Returns Mon Oct 05 2015 08:54:00 GMT+0530 (IST) in Chrome
new Date('2015-10-05T03:24:00'); // Returns 2015-10-04T21:54:00.000Z in Firefox
var date1 = '2015-08-20 09:38:20';
var date1Updated = new Date(date1.replace(/-/g,'/'));
alert(date1Updated.getMonth());
var strDate = addZero(d.getDate()) + "/" + addZero((d.getMonth() + 1))+"/" +d.getFullYear();
alert("strDate :"+strDate)
return strDate;
}
function addZero(i) {
if (i < 10) {
i = "0" + i;
}
return i;
}
The getMonth() method returns the month (from 0 to 11) for the specified date, according to local time.
Note: January is 0, February is 1, and so on.
you need to add one like getMonth() + 1.
function formatDate(dt) {
//var date = new Date(dt);
var date = new Date('2015-08-27 16:00:00');
//alert(date.getMonth() + 1);
var hours = date.getHours();
var minutes = date.getMinutes();
var seconds = date.getSeconds();
var ampm = hours >= 12 ? 'pm' : 'am';
hours = hours % 12;
hours = hours ? hours : 12; // the hour '0' should be '12'
minutes = minutes < 10 ? '0' + minutes : minutes;
var strTime = hours + ':' + minutes + ':' + seconds + ' ' + ampm;
return date.getDate() + " " + (date.getMonth() + 1) + " " + date.getFullYear() + " " + strTime;
}
alert(formatDate());
In firefox '2015-08-27 16:00:00' is an invalid date.
Your options are
var today = new Date();
var birthday = new Date('December 17, 1995 03:24:00');
var birthday = new Date('1995-12-17T03:24:00');
var birthday = new Date(1995, 11, 17);
var birthday = new Date(1995, 11, 17, 3, 24, 0);
In your case you're missing the T before the time
Documentation
You have an invalid date format, It seems Chrome handle this situation but firefox not.
new Date('2015-08-27 16:00:00') // Invalid format
new Date('2015-08-27T16:00:00') // Correct Format With T
Your code doesn't work in firefox
In firefox 2015-08-27 16:00:00isn't valid.
To be valid it has to be 2015-08-27T16:00:00.
To make it valid in firefox, the easiest solution would be
function formatDate(dt) {
//var date = new Date(dt);
var sampleDate = "2015-08-27 16:00:00"; // Your sample date as string
var another = sampleDate.replace(' ', 'T');// Change here. Replaced the empty space with the 'T' to make it work in firefox
var date = new Date(another); alert(date.getMonth()); // Using your date to create new Date object
var hours = date.getHours();
var minutes = date.getMinutes();
var seconds = date.getSeconds();
var ampm = hours >= 12 ? 'pm' : 'am';
hours = hours % 12;
hours = hours ? hours : 12; // the hour '0' should be '12'
minutes = minutes < 10 ? '0' + minutes : minutes;
var strTime = hours + ':' + minutes + ':' + seconds + ' ' + ampm;
return date.getDate() + " " + date.getMonth() + " " + date.getFullYear() + " " + strTime;
}
Hope i was helpfull
Parsing strings using the Date constructor is largely implementation dependent. Only one format of string is specified as being supported by the specification and that changed to some extent between ES5 and ECMAScript 2015.
Your best option is to manually parse the string, either using your own function or a library. The following will suit if the string is consistently the format in the OP and the timezone is UTC:
/* parse dates of format yyyy-mm-dd hh:mm:ss
** e.g. 2015-08-27 16:00:00
**
** #param {string} s - Date string in format yyyy-mm-dd hh:mm:ss
** #returns {Date} - String as Date assuming UTC
**
** Does not validate that the string is valid date or time
**/
function parseDate (s) {
var b = s.split(/\D/);
return new Date(Date.UTC(b[0], b[1]-1, b[2], b[3], b[4], b[5]));
}
document.write(parseDate('2015-08-27 16:00:00'));
I have a datepicker returning a date string, and a timepicker returning just a time string.
How should I combine those into a single javascript Date?
I thought I found a solution in Date.js. The examples shows an at( )-method, but I can't find it in the library...
You can configure your date picker to return format like YYYY-mm-dd (or any format that Date.parse supports) and you could build a string in timepicker like:
var dateStringFromDP = '2013-05-16';
$('#timepicker').timepicker().on('changeTime.timepicker', function(e) {
var timeString = e.time.hour + ':' + e.time.minute + ':00';
var dateObj = new Date(datestringFromDP + ' ' + timeString);
});
javascript Date object takes a string as the constructor param
Combine date and time to string like this:
1997-07-16T19:20:15
Then you can parse it like this:
Date.parse('1997-07-16T19:20:15');
You could also use moment.js or something similar.
For plain JavaScript:
combineDateAndTime = function(date, time) {
timeString = time.getHours() + ':' + time.getMinutes() + ':00';
var year = date.getFullYear();
var month = date.getMonth() + 1; // Jan is 0, dec is 11
var day = date.getDate();
var dateString = '' + year + '-' + month + '-' + day;
var combined = new Date(dateString + ' ' + timeString);
return combined;
};
You can concatenate the date and time, and then use moment to get the datetime
const date = '2018-12-24';
const time = '23:59:59';
const dateTime = moment(`${date} ${time}`, 'YYYY-MM-DD HH:mm:ss').format();
Boateng's example fails in cases where time consisted of hours, minutes, days or months that ranged from values 0-9 as getDate(), getMonth() etc... will return 1 digit in these cases and the time string will fail and an invalid date is returned:
function CombineDateAndTime(date, time) {
const mins = ("0"+ time.getMinutes()).slice(-2);
const hours = ("0"+ time.getHours()).slice(-2);
const timeString = hours + ":" + mins + ":00";
const year = date.getFullYear();
const month = ("0" + (date.getMonth() + 1)).slice(-2);
const day = ("0" + date.getDate()).slice(-2);
const dateString = "" + year + "-" + month + "-" + day;
const datec = dateString + "T" + timeString;
return new Date(datec);
};
Unfortunately do not have enough rep to comment
David's example with slight modifications:
function CombineDateAndTime(date, time) {
var timeString = time.getHours() + ':' + time.getMinutes() + ':00';
var ampm = time.getHours() >= 12 ? 'PM' : 'AM';
var year = date.getFullYear();
var month = date.getMonth() + 1; // Jan is 0, dec is 11
var day = date.getDate();
var dateString = '' + year + '-' + month + '-' + day;
var datec = dateString + 'T' + timeString;
var combined = new Date(datec);
return combined;
};
Concate date and time with moment JS which also works on firefox,
let d1 = moment().format('MM/DD/YYYY');
let dateTimeOpen = moment(d1 + ' ' + model.openingTime).format('YYYY-MM-DD HH:mm:ss');
let dateTimeClose = moment(d1 + ' ' + model.closingTime).format('YYYY-MM-DD HH:mm:ss');
const date = "2022-12-27";
const time = "16:26:42";
new Date(`${date}T${time});
output
Date Tue Dec 27 2022 16:26:42 GMT+0100 (Central European Standard Time)
