Formatting Dates in JavaScript

For example, the formatDate() method formats a date based on the formatString parameter set as the second argument.

1formatDate (String | Number | Date date, String formatString)

The date parameter can be a String, Number, or most typically a JavaScript Date. If you provide a String value, use ISO 8601 format to avoid parsing warnings.

The formatString parameter contains tokens to format a date and time. For example, "YYYY-MM-DD" formats 15th January, 2017 as "2017-01-15". The default format string comes from the $Locale value provider.

This table shows the list of tokens supported in formatString.

There are similar methods that differ in their default output values.

• formatDateTime()—The default formatString outputs datetime instead of date.
• formatDateTimeUTC()—Formats a datetime in UTC standard time.
• formatDateUTC()—Formats a date in UTC standard time.
