What does DatePipe do?
DatePipe formats a date value according to locale rules.
Syntax
{{ value_expression | date [ : format [ : timezone [ : locale ] ] ] }}Where
value (any) = The date expression: a Date object, a number (milliseconds since UTC epoch), or an ISO string. The parameter is required.
format (string) = The date/time components to include, using predefined options or a custom format string. It is optional. Default value is ‘mediumDate‘.
timezone (string) = A timezone offset (such as ‘+0430’), or a standard UTC/GMT or continental US timezone abbreviation. When not supplied, uses the end-user’s local system timezone. It is optional. Default is undefined.
locale (string) = A locale code for the locale format rules to use. When not supplied, uses the value of LOCALE_ID, which is en-US by default. See Setting your app locale. It is optional. Default is undefined.
