Operation With Dates In JavaScript

JavaScript provides a number of built-in functions and methods for working with dates. Here are some examples:

Creating a new date object:

const now = new Date();
const specificDate = new Date(2022, 2, 14);
const specificDateTime = new Date(2022, 2, 14, 10, 30, 0);

Output

March 14, 2022

March 14, 2022, 10:30:00 AM

Getting various components of a date:

const date = new Date();
const year = date.getFullYear(); // 2023
const month = date.getMonth(); // 1 (February is 1, not 0)
const day = date.getDate(); // 17
const hour = date.getHours(); // 15
const minute = date.getMinutes(); // 30
const second = date.getSeconds(); // 0
const millisecond = date.getMilliseconds(); // 0
const weekday = date.getDay(); // 4 (Thursday is 4, not 0)

Setting various components of a date:

const date = new Date();
date.setFullYear(2022);
date.setMonth(2);
date.setDate(14);
date.setHours(10);
date.setMinutes(30);
date.setSeconds(0);
date.setMilliseconds(0);

Converting a date to a string:

const date = new Date();
const dateString = date.toString();
const isoString = date.toISOString();

Output

“Thu Feb 17 2023 15:30:00 GMT-0800 (Pacific Standard Time)”

“2023-02-18T00:30:00.000Z”

Comparing dates:

const date1 = new Date(2023, 2, 14);
const date2 = new Date(2022, 1, 1);
if (date1 > date2) {
  console.log("date1 is later than date2");
}

These are just a few examples of the many operations you can perform with dates in JavaScript. For more information, you can refer to the JavaScript documentation on dates and times.
