I want to get current time in a specific format with javascript.
With the function below and calling it will give me Fri Feb 01 2013 13:56:40 GMT+1300 (New Zealand Daylight Time) but I want to format it like Friday 2:00pm 1 Feb 2013
var d = new Date();
var x = document.getElementById("time");
x.innerHTML = d;
Of course, code above doesn't have any formatting logic but I have not come across with any "working" formatters yet.
This question is related to
javascript
date
time
format
You may want to try
var d = new Date();
d.toLocaleString(); // -> "2/1/2013 7:37:08 AM"
d.toLocaleDateString(); // -> "2/1/2013"
d.toLocaleTimeString(); // -> "7:38:05 AM"
2017 update: use toLocaleDateString and toLocaleTimeString to format dates and times. The first parameter passed to these methods is a locale value, such as en-us. The second parameter, where present, specifies formatting options, such as the long form for the weekday.
let date = new Date(); _x000D_
let options = { _x000D_
weekday: "long", year: "numeric", month: "short", _x000D_
day: "numeric", hour: "2-digit", minute: "2-digit" _x000D_
}; _x000D_
_x000D_
console.log(date.toLocaleTimeString("en-us", options));
_x000D_
Output : Wednesday, Oct 25, 2017, 8:19 PM
Please refer below link for more details.
function startTime() {
var today = new Date(),
h = checkTime(((today.getHours() + 11) % 12 + 1)),
m = checkTime(today.getMinutes()),
s = checkTime(today.getSeconds());
document.getElementById('demo').innerHTML = h + ":" + m + ":" + s;
t = setTimeout(function () {
startTime()
}, 500);
}
startTime();
})();
05:12:00
function formatTime(date){
d = new Date(date);
var h=d.getHours(),m=d.getMinutes(),l="AM";
if(h > 12){
h = h - 12;
}
if(h < 10){
h = '0'+h;
}
if(m < 10){
m = '0'+m;
}
if(d.getHours() >= 12){
l="PM"
}else{
l="AM"
}
return h+':'+m+' '+l;
}
Usage & result:
var formattedTime=formatTime(new Date('2020 15:00'));
// Output: "03:00 PM"
To work with the base Date class you can look at MDN for its methods (instead of W3Schools due to this reason). There you can find a good description about every method useful to access each single date/time component and informations relative to whether a method is deprecated or not.
Otherwise you can look at Moment.js that is a good library to use for date and time processing. You can use it to manipulate date and time (such as parsing, formatting, i18n, etc.).
There are many great libraries out there, for those interested
There really shouldn't be a need these days to invent your own formatting specifiers.
d = Date.now();_x000D_
d = new Date(d);_x000D_
d = (d.getMonth()+1)+'/'+d.getDate()+'/'+d.getFullYear()+' '+(d.getHours() > 12 ? d.getHours() - 12 : d.getHours())+':'+d.getMinutes()+' '+(d.getHours() >= 12 ? "PM" : "AM");_x000D_
_x000D_
console.log(d);
_x000D_
Look at the internals of the Date class and you will see that you can extract all the bits (date, month, year, hour, etc).
http://www.w3schools.com/jsref/jsref_obj_date.asp
For something like Fri 23:00 1 Feb 2013
the code is like:
date = new Date();_x000D_
_x000D_
weekdayNames = ['Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat'];_x000D_
monthNames = ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"];_x000D_
var dateString = weekdayNames[date.getDay()] + " " _x000D_
+ date.getHours() + ":" + ("00" + date.getMinutes()).slice(-2) + " " _x000D_
+ date.getDate() + " " + monthNames[date.getMonth()] + " " + date.getFullYear();_x000D_
_x000D_
console.log(dateString);
_x000D_

I can't recommend the use of Moment enough. If you are able to use third-party libraries, I highly recommend doing so. Beyond just formatting, it deals with timezones, parsing, durations and time travel extremely well and will pay dividends in simplicity and time (at the small expense of size, abstraction and performance).
You wanted something that looked like this:
Friday 2:00pm 1 Feb 2013
Well, with Moment all you need you to do is this:
import Moment from "moment";
Moment().format( "dddd h:mma D MMM YYYY" ); //=> "Wednesday 9:20am 9 Dec 2020"
And if you wanted to match that exact date and time, all you would need to do is this:
import Moment from "moment";
Moment( "2013-2-1 14:00:00" ).format( "dddd h:mma D MMM YYYY" ) ); //=> "Friday 2:00pm 1 Feb 2013"
There's a myriad of other formatting options that can be found here.
Go to their home page to see more detailed instructions, but if you're using npm or yarn it's as simple as:
npm install moment --save
or
yarn add moment
For this true mysql style use this function below: 2019/02/28 15:33:12
function getDateTime() {_x000D_
var now = new Date(); _x000D_
var year = now.getFullYear();_x000D_
var month = now.getMonth()+1; _x000D_
var day = now.getDate();_x000D_
var hour = now.getHours();_x000D_
var minute = now.getMinutes();_x000D_
var second = now.getSeconds(); _x000D_
if(month.toString().length == 1) {_x000D_
month = '0'+month;_x000D_
}_x000D_
if(day.toString().length == 1) {_x000D_
day = '0'+day;_x000D_
} _x000D_
if(hour.toString().length == 1) {_x000D_
hour = '0'+hour;_x000D_

if(minute.toString().length == 1) {_x000D_
minute = '0'+minute;_x000D_
}_x000D_
if(second.toString().length == 1) {_x000D_

} _x000D_
var dateTime = year+'/'+month+'/'+day+' '+hour+':'+minute+':'+second; _x000D_
return dateTime;_x000D_
