Question

On a page that I’m building, there is a requirement to either display the date (eg: 15 Aug) or, if the date is today, just display a time, eg: 10pm.

What would be the best way of coaxing that behaviour out of moment.js?

The format i’d like for a date is ‘d MMM’ and the format for time would be ‘hA’ (if minutes are 0) or ‘h:mmA’ (if minutes are not 0).

Any ideas on how to approach this? It looks like the calendar() function might be able to support something like that?

Answer 1

You want to use moment.calendar: set everything except sameDay to d MMMM and sameDay to h:mmA. You can’t do finer grain than that.

function timeTodayDateElse(date){
    moment.lang('en', {
        'calendar' : {
            'lastDay' : 'D MMMM',
             'sameDay' : 'h:mmA',
            'nextDay' : 'D MMMM',
            'lastWeek' : 'D MMMM',
            'nextWeek' : 'D MMMM',
            'sameElse' : 'D MMMM'
       }
    });

    return moment(date).calendar();
}
