Current time formatting with Javascript

Question

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

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:

_x000D_

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_

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

A JavaScript Date has several methods allowing you to extract its parts   getFullYear   - Returns the 4-digit year 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   There are no built-in methods allowing you to get localized strings like  Friday    February   or  PM    You have to code that yourself   To get the string you want  you at least need to store string representations of days and months   var months     Jan    Feb    Mar    Apr    May    Jun    Jul    Aug    Sep    Oct    Nov    Dec    var days     Sunday    Monday    Tuesday    Wednesday    Thursday    Friday    Saturday      Then  put it together using the methods above    x000D   x000D  var months     Jan    Feb    Mar    Apr    May    Jun    Jul    Aug    Sep    Oct    Nov    Dec    x000D  var days     Sunday    Monday    Tuesday    Wednesday    Thursday    Friday    Saturday    x000D  var d   new Date    x000D  var day   days d getDay     x000D  var hr   d getHours    x000D  var min   d getMinutes    x000D  if  min  lt  10    x000D      min    0    min  x000D    x000D  var ampm    am   x000D  if  hr  gt  12     x000D      hr -

Using Moment  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   Usage 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  quot moment quot    Moment   format   quot dddd h mma D MMM YYYY quot         gt   quot Wednesday 9 20am 9 Dec 2020 quot   And if you wanted to match that exact date and time  all you would need to do is this  import Moment from  quot moment quot    Moment   quot 2013-2-1 14 00 00 quot    format   quot dddd h mma D MMM YYYY quot           gt   quot Friday 2 00pm 1 Feb 2013 quot   There s a myriad of other formatting options that can be found here  Install 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
