I have a date in string format:
Wed Jul 20 2016 14:01:01 GMT-0300 (BRT)
And I would like to extract the date and days and time in such a way that I can form a string like this:
Quarta-Feira, 20-07-2016 as 17:01

If the idea is to present a more beautiful date to the user, there is a simpler way to do, in a similar but different format:
//se a data fosse: new Date('Tue Aug 02 2016 15:28:14 GMT-0300 (BRT)');
var data = new Date();
var options = {
weekday: "long", year: "numeric", month: "long",
day: "2-digit", hour: "2-digit", minute: "2-digit"
}
//terça-feira, 02 de agosto de 2016 15:28
data.toLocaleDateString('pt-BR', options);
And if you’re going to format it in the wood you want, it would be basically like this:
var data = new Date();
var optionsWeek = {
weekday: "long"
}
var hourMinute = {
day: "2-digit", hour: "2-digit", minute: "2-digit"
}
var week = data.toLocaleDateString('pt-BR', optionsWeek);
var hm = data.toLocaleDateString('pt-BR', hourMinute);
var dateFormatted = data.toLocaleDateString('pt-BR')
.replace(/\//g,'-');
var sDate = (week.substr(0,1)).toUpperCase() +
week.substr(1) + ', ' +
dateFormatted + ' as ' +
hm.substr(3);
console.log(sDate);

Here is what you asked to +. Now you can convert 2 correct style dates 2016-07-20T15:01:01-02:00 and style Wed Jul 20 2016 14:01:01 GMT-0300 (BRT).
Date.toBrazilianFormat = (function() {
// Dias da semana (de inglês abreviado para português)
var weeks = {
"Sun": "Domingo",
"Mon": "Segunda-feira",
"Tur": "Ter\xe7a-feira",
"Wed": "Quarta-feira",
"Thu": "Quinta-feira",
"Fri": "Sexta-feira",
"Sat": "S\xe1bado"
},
// Número sequencial dos meses do ano
monthies = {
"Jan": 1,
"Feb": 2,
"Mar" : 3,
"Apr" : 4,
"May" : 5,
"Jun" : 6,
"Jul" : 7,
"Aug" : 8,
"Sep" : 9,
"Oct" : 10,
"Nov" : 11,
"Dec" : 12
};
return (function(date) {
if(typeof date !== 'string')
date = 'Sun Jan 10 1999 14:01:01 GMT-0300 (BRT)';
// Partes do horário (separadas por barras de espaço)
var bparts = date.split(' ');
// Verifica se o primeiro conjunto de caracteres são números
for(var i = 0, charCode;
(charCode = bparts[0].charCodeAt(i)) &&
charCode >= 48 &&
charCode <= 57;
i ++);
// Verifica se a data começa com um ano
if(bparts.length === 1 && i >= 2) {
// Partes da data (separadas por hífens)
var hparts = date.split('-');
// Ano
var year = hparts[0],
// Mês do ano
month = parseFloat(hparts[1]),
// Dia do mês
day = parseFloat(hparts[2].substring(0, hparts[2].indexOf('T')));
/* Parece que não há o dia da semana nessa data. */
// Partes do horário
var tparts = hparts[3].substring(1).split(':');
// Horas
var hours = parseFloat(tparts[0]),
// Minutos
min = tparts[1];
// Adiciona o 0 na frente dos números se necessário.
hours = hours <= 9 ? '0' + hours : hours;
day = day <= 9 ? '0' + day : day;
month = month <= 9 ? '0' + month : month;
// Retorna o data como string.
return day + '-' + month + '-' + year +
' às ' + hours + ':' + min;
}else{
// Partes do horário (separados por dois pontos)
var tparts = bparts[4].split(':');
// Dia do mês
var day = bparts[2],
// Mês
month = monthies[bparts[1]],
// +3 horas
hours = (parseFloat(tparts[0]) + 3) % 24,
// Minutos
min = tparts[1],
// Dia da semana
week = weeks[bparts[0]],
// Ano
year = bparts[3];
// Adiciona o 0 na frente dos números se necessário.
hours = hours <= 9 ? '0' + hours : hours;
day = day <= 9 ? '0' + day : day;
month = month <= 9 ? '0' + month : month;
// Retorna a data como string.
return week + ', ' +
day + '-' + month + '-' + year +
' às ' + hours + ':' + min;
}
});
})();
Example of use:
Date.toBrazilianFormat('2016-07-20T15:01:01-02:00'); // 20-07-2016 às 02:00
That date does not have the day of the week scheduled, so it was ignored.

I think there is no native method to convert this date into Javascript, but it is possible to do this manually.
Edit: After seeing the reply of @Ivanferrer I realized that there is already native method to do date conversion.
// Raw da data
var rawdate = "Wed Jul 20 2016 14:01:01 GMT-0300 (BRT)",

parts = rawdate.split(' '),
// Partes do horário (separados por dois pontos)
timeParts = parts[4].split(':');
// Dias da semana (de inglês abreviado para português)
var weeks = {
"Sun": "Domingo",
"Mon": "Segunda-feira",

You have to set locale in javascript to en-BR but I recommend using a library to manipulate dates. http://momentjs.com/

Yeah, I know this library, but I couldn’t find any method of it.

I updated the code in my reply. I got a bug where the hours could be longer than
23, I just modified that line:" às " + (parseFloat(date.time.hours) + 3) + ":" + date.time.minutes;for" às " + ((parseFloat(date.time.hours) + 3) % 24) + ":" + date.time.minutes;. Now you’re safer.– Klaider
Great, thank you very much. Please, if you know and have time, you could put an answer if I have a date in this format:
2016-07-20T15:01:01-02:00, and with the same answer:Quarta-Feira, 20-07-2016 as 15:01. @Theprohands– Jonathan
