Date.prototype.getMonth()

The getMonth() method returns the month in the specified date according to local time, as a zero-based value (where zero indicates the first month of the year).

An integer number, between 0 and 11, representing the month in the given date according to local time. 0 corresponds to January, 1 to February, and so on.

The second statement below assigns the value 11 to the variable month, based on the value of the Date object Xmas95.

var Xmas95 = new Date('December 25, 1995 23:15:30');
var month = Xmas95.getMonth();

console.log(month); // 11

var options = { month: 'long'};
console.log(new Intl.DateTimeFormat('en-US', options).format(Xmas95));
// December
console.log(new Intl.DateTimeFormat('de-DE', options).format(Xmas95));
// Dezember
