JavaScript Date Get the current time and date
Example
Use new Date() to generate a new Date object containing the current date and time.
Note that Date() called without arguments is equivalent to new Date(Date.now()).
Once you have a date object, you can apply any of the several available methods to extract its properties (e.g. getFullYear() to get the 4-digits year).
Below are some common date methods.
Get the current year
var year = (new Date()).getFullYear();
console.log(year);
// Sample output: 2016
Get the current month
var month = (new Date()).getMonth();
console.log(month);
// Sample output: 0
Please note that 0 = January. This is because months range from 0 to 11, so it is often desirable to add +1 to the index.
Get the current day
var day = (new Date()).getDate();
console.log(day);
// Sample output: 31
Get the current hour
var hours = (new Date()).getHours();
console.log(hours);
// Sample output: 10
Get the current minutes
var minutes = (new Date()).getMinutes();
console.log(minutes);
// Sample output: 39
Get the current seconds
var seconds = (new Date()).getSeconds();
console.log(second);
// Sample output: 48
Get the current milliseconds
To get the milliseconds (ranging from 0 to 999) of an instance of a Date object, use its getMilliseconds method.
var milliseconds = (new Date()).getMilliseconds();
console.log(milliseconds);
// Output: milliseconds right now
Convert the current time and date to a human-readable string
var now = new Date();
// convert date to a string in UTC timezone format:
console.log(now.toUTCString());
// Output: Wed, 21 Jun 2017 09:13:01 GMT
The static method Date.now() returns the number of milliseconds that have elapsed since 1 January 1970 00:00:00 UTC. To get the number of milliseconds that have elapsed since that time using an instance of a Date object, use its getTime method.
// get milliseconds using static method now of Date
console.log(Date.now());
// get milliseconds using method getTime of Date instance
console.log((new Date()).getTime());
