const event = new Date(Date.UTC(2012, 11, 20, 3, 0, 0));

const options = {  year: 'numeric', month: 'short', day: 'numeric' };

console.log(event.toLocaleDateString('de-DE', options));
// expected output: Donnerstag, 20. Dezember 2012

console.log(event.toLocaleDateString('en-US', options));
// US format 


// In case you only want the month
console.log(event.toLocaleDateString(undefined, { month: 'short'}));
console.log(event.toLocaleDateString(undefined, { month: 'long'}));

const t = new Date();
const date = ('0' + t.getDate()).slice(-2);
const month = ('0' + (t.getMonth() + 1)).slice(-2);
const year = t.getFullYear();
const hours = ('0' + t.getHours()).slice(-2);
const minutes = ('0' + t.getMinutes()).slice(-2);
const seconds = ('0' + t.getSeconds()).slice(-2);
const time = `${date}/${month}/${year}, ${hours}:${minutes}:${seconds}`;

output: "27/04/2020, 12:03:03"
