Wrong plural usage for time in PT-BR

[viniciusbm]

There is a problem with the following definitions for Brazilian Portuguese:

    longDateFormat : {
        LT : 'HH:mm',
        LTS : 'HH:mm:ss',
        L : 'DD/MM/YYYY',
        LL : 'D [de] MMMM [de] YYYY',
        LLL : 'D [de] MMMM [de] YYYY [às] HH:mm',
        LLLL : 'dddd, D [de] MMMM [de] YYYY [às] HH:mm'
    },
    calendar : {
        sameDay: '[Hoje às] LT',
        nextDay: '[Amanhã às] LT',
        nextWeek: 'dddd [às] LT',
        lastDay: '[Ontem às] LT',
        lastWeek: function () {
            return (this.day() === 0 || this.day() === 6) ?
                '[Último] dddd [às] LT' : // Saturday + Sunday
                '[Última] dddd [às] LT'; // Monday - Friday
        },
        sameElse: 'L'
    }

The string "às" should only be used if the hour (in 24-hour format) is at least 2. If H == 0 or H == 1, "à" should be used instead.

I managed to find a solution for the calendar part (I only tested this by extending the locale with updateLocale):

    calendar:  {
        sameDay: function() { return '[Hoje] ' + (this.hours() < 2 ? '[à]' : '[às]') + ' LT'; },
        nextDay: function() { return '[Amanhã] ' + (this.hours() < 2 ? '[à]' : '[às]') + ' LT'; },
        nextWeek: function() { return 'dddd ' + (this.hours() < 2 ? '[à]' : '[às]') + ' LT'; },
        lastDay: function() { return '[Ontem] ' + (this.hours() < 2 ? '[à]' : '[às]') + ' LT'; },
        lastWeek: function () {
            return (this.day() === 0 || this.day() === 6) ?
                '[Último] dddd ' + (this.hours() < 2 ? '[à]' : '[às]') + ' LT': // Saturday + Sunday
                '[Última] dddd ' + (this.hours() < 2 ? '[à]' : '[às]') + ' LT'; // Monday - Friday
        },
        sameElse: 'L'
    }

However, I cannot do the same with longDateFormat, because its values apparently cannot be functions.

Is there a solution for this (by either editing pt_br.js or extending the locale externally)?

Thank you

I guess we'd need a code change to allow them to be functions

As a brazilian, I don't understand what is the problem here...

I think it's correct to say: "Hoje às 00:00" or "Hoje às 01:00", right?

Wrong.

In “à(s) xx:00” — which is read as “à(s) xx hora(s)” —, the “à(s)” is a contraction of the preposition “a” with the article “a(s)”. The article refers to “xx hora(s)”, so it cannot be plural if xx is less than 2. Therefore, we must say “à 0 hora”, “à 1 hora”, “às 2 horas”, “às 3 horas”, and so on.

For the same reason, if we want to say the current time (“it’s...”), we must use “é” (and not “são”) before “zero hora”, “uma hora”, “meio-dia” and “meia-noite”.

If you have questions about this topic, I recommend checking some grammar, such as Moderna Gramática Portuguesa by Evanildo Bechara.

I’m Brazilian too, and I know that even in Brazil it’s common to hear these expressions used incorrectly. However, I think Moment.js should still display them properly.
