You can also convert one format of date into desired format using Momentjs.

Momentjs helps you to display relative time which can be used in applications which have chats and notifications.

moment("20111031", "YYYYMMDD").fromNow(); // 8 years ago
moment("20120620", "YYYYMMDD").fromNow(); // 7 years ago
moment().startOf('day').fromNow();        // 12 hours ago
moment().endOf('day').fromNow();          // in 12 hours

The calendar time can be retrieved using calendar method.

moment().subtract(10, 'days').calendar(); // 10/19/2019
moment().subtract(6, 'days').calendar();  // Last Wednesday at 12:28 PM
moment().subtract(3, 'days').calendar();  // Last Saturday at 12:28 PM
moment().subtract(1, 'days').calendar();  // Yesterday at 12:28 PM
moment().calendar();                      // Today at 12:28 PM
moment().add(1, 'days').calendar();       // Tomorrow at 12:28 PM
