MomentJS - String

This will take string as date for parsing with moment.

Syntax

moment(string)

Observe the following examples and their outputs when different date strings are given to moment.

Example 1

var day = moment("2017-04-15");

To display the date, we have used day._d to get the date details from the moment.

Output

Example 2

var day = moment("2017-W10-5");

var day = moment("2017W105");

Observe that in the string "2017-W10-5" given to the moment, W represents the week. You can observe the following output, where W10 falls for March month.

Output

Example 3

var day = moment("2017-080");

var day = moment("2017080");

Here, the string 2017-080 is the 80th day which falls on March 21st as shown below.

Output

Example 4

var day = moment("2017-05-08T09");

var day = moment("20170508T09");

Here, the string 2017-05-08T09 is given to moment where the number after T represents the hour to be shown.

Output

Example 5

var day = moment("2017-06-08 06:30:26");

var day = moment("20170608T063026");

We can also pass the hour, minutes, or seconds to the moment and the output as follows −

Output

Z or ZZ	+12:00	Offset from UTC as +-HH:mm, +-HHmm, or Z

You can check if date is valid as per the string formats using the command as shown −

var day = moment('2018.05.25', 'YYYY-MM-DD').isValid();

As you can observe in the output shown below, this will return true since the date is in proper format: YYYY, MM, and DD.

If the same date is changed as given below, the output will be false, as shown below −

var day = moment('05.25', 'YYYY-MM-DD').isValid();

You can also format the date as per your requirement as shown in the following examples −

Example 1

var day = moment('2018/05/25').format("YYYY-MM-DD");

Output

Example 2

var day = moment('20170608T063026').format("YYYY-MM-DD HH:mm:ss");

Output

Example 3

var day = moment("634", "Hmm").format("HH:mm");

Output

Example

It is possible to parse multiple formats, where the formats are passed in array form as shown below −

var day = moment("12-25-1995",["MM-DD-YYYY", "YYYY-MM-DD"]).isValid();

Output

Since the given date matches with one of the formats, the output given is true.
