Date.prototype.getMonth() - JavaScript | MDN
Try it
const moonLanding = new Date("July 20, 69 00:20:18");
console.log(moonLanding.getMonth()); // (January gives 0)
// Expected output: 6
Syntax
Parameters
None.
Return value
An integer, between 0 and 11, representing the month for the given date according to local time: 0 for January, 1 for February, and so on. Returns NaN if the date is invalid.
Description
The return value of getMonth() is zero-based, which is useful for indexing into arrays of months, for example:
js
const valentines = new Date("1995-02-14");
const month = valentines.getMonth();
const monthNames = ["January", "February", "March" /* , … */];
console.log(monthNames[month]); // "February"
However, for the purpose of internationalization, you should prefer using Intl.DateTimeFormat with the options parameter instead.
js
const options = { month: "long" };
console.log(new Intl.DateTimeFormat("en-US", options).format(valentines));
// "February"
console.log(new Intl.DateTimeFormat("de-DE", options).format(valentines));
// "Februar"
Examples
Using getMonth()
The month variable has value 11, based on the value of the Date object xmas95.
js
const xmas95 = new Date("1995-12-25T23:15:30");
const month = xmas95.getMonth();
console.log(month); // 11
