Getting current date and time in JavaScript

Question

I have a script that prints the current date and time in JavaScript  but the DATE is always wrong  Here is the code  var currentdate   new Date    var datetime    quot Last Sync   quot    currentdate getDay      quot   quot    currentdate getMonth       quot   quot    currentdate getFullYear      quot     quot     currentdate getHours      quot   quot     currentdate getMinutes      quot   quot    currentdate getSeconds     It should print 18 04 2012 15 07 33 and prints 3 3 2012 15 07 33

getMonth   returns a zero-based number so to get the correct month you need to add 1  so calling  getMonth   in may will return 4 and not 5   So in your code we can use currentdate getMonth   1 to output the correct value  In addition     getDate   returns the day of the month  lt - this is the one you want  getDay   is a separate method of the Date object which will return an integer representing the current day of the week  0-6  0    Sunday etc   so your code should look like this   var currentdate   new Date     var datetime    Last Sync      currentdate getDate                            currentdate getMonth   1                            currentdate getFullYear                               currentdate getHours                             currentdate getMinutes                            currentdate getSeconds           JavaScript Date instances inherit from Date prototype  You can modify the constructor s prototype object to affect properties and methods inherited by JavaScript Date instances   You can make use of the Date prototype object to create a new method which will return today s date and time  These new methods or properties will be inherited by all instances of the Date object thus making it especially useful if you need to re-use this functionality      For todays date  Date prototype today   function           return   this getDate    lt  10   0        this getDate           this getMonth   1   lt  10   0         this getMonth   1        this getFullYear          For the time now Date prototype timeNow   function           return   this getHours    lt  10   0        this getHours           this getMinutes    lt  10   0        this getMinutes           this getSeconds    lt  10   0        this getSeconds        You can then simply retrieve the date and time by doing the following   var newDate   new Date    var datetime    LastSync      newDate today             newDate timeNow      Or call the method inline so it would simply be -  var datetime    LastSync      new Date   today             new Date   timeNow

To get time and date you should use       new Date   toLocaleString      gt  gt   09 08 2014  2 35 56 AM    To get only the date you should use       new Date   toLocaleDateString      gt  gt   09 08 2014    To get only the time you should use       new Date   toLocaleTimeString      gt  gt   2 35 56 AM    Or if you just want the time in the format hh mm without AM PM for US English      new Date   toLocaleTimeString  en-US     hour12  false                                                hour   numeric                                                 minute   numeric      gt  gt   02 35    or for British English      new Date   toLocaleTimeString  en-GB     hour   numeric                                                 minute   numeric       gt  gt   02 35    Read more here

getDay returns day of week  You need  getDate instead   getMonth returns values from 0 to 11  You ll need to add 1 to the result to get  human  month number

User · Answer

You need to use getDate   to get the date part  The getDay   function returns the day number  Sunday   0  Monday   1      and the getMonth   returns a 0 based index  so you need to increment it by 1    var currentdate   new Date       var datetime    Last Sync      currentdate getDate            parseInt currentdate getMonth         1             currentdate getFullYear                  currentdate getHours                currentdate getMinutes           currentdate getSeconds

This question is quite old and the answers are too  Instead of those monstrous functions  we now can use moment js to get the current date  which actually makes it very easy  All that has to be done is including moment js in our project and get a well formated date  for example  by   moment   format  dddd  MMMM Do YYYY  h mm ss a      I think that makes it way easier to handle dates in javascript
