Javascript: Get Month/year/day From Unix Timestamp

I have a unix timestamp, e.g., 1313564400000.00. How do I convert it into Date object and get month/year/day accordingly? The following won't work: function getdhm(timestamp) {

Solution 1:

var date = newDate(1313564400000);
var month = date.getMonth();

etc.

This will be in the user's browser's local time.

Solution 2:

Instead of using parse, which is used to convert a date string to a Date, just pass it into the Date constructor:

var date=newDate(timestamp);

Make sure your timestamp is a Number, of course.

Solution 3:

An old question, but none of the answers seemed complete, and an update for 2020:

For example: (you may have a decimal if using microsecond precision, e.g. performance.now())

let timestamp = 1586438912345.67;

And we have:

var date = newDate(timestamp); // Thu Apr 09 2020 14:28:32 GMT+0100 (British Summer Time)let year = date.getFullYear(); // 2020let month = date.getMonth() + 1; // 4 (note zero index: Jan = 0, Dec = 11)let day = date.getDate(); // 9

And if you'd like the month and day to always be a two-digit string (e.g. "01"):

let month = (date.getMonth() + 1).toString().padStart(2, '0'); // "04"let day = date.getDate().toString().padStart(2, '0'); // "09"

For extended completeness:

let hour = date.getHours(); // 14let minute = date.getMinutes(); // 28let second = date.getSeconds(); // 32let millisecond = date.getMilliseconds(); // 345let epoch = date.getTime(); // 1586438912345 (Milliseconds since Epoch time)

Further, if your timestamp is actually a string to start (maybe from a JSON object, for example):

var date = newDate(parseFloat(timestamp));

or for right now:

var date = newDate(Date.now());
