Date Object

JavaScript uses the Date object to handle date and time information.

In JavaScript, you can create a new date object using new Date().

Copy
const now = new Date();
console.log(now); // Outputs the current date and time

When a Date object is created, it contains the current date and time information. You can set or retrieve the date and time information in various ways as shown below.

You can set a specific date and time when creating a Date object.

Copy
const birthDay = new Date('1995-07-20');
console.log(birthDay);

You can retrieve specific information from a Date object.

Copy
const now = new Date();

// Year
const year = now.getFullYear();

// Month (starts at 0, so add 1)
const month = now.getMonth() + 1;

// Day
const date = now.getDate();

// Hour
const hours = now.getHours();

// Minute
const minutes = now.getMinutes();

// Second
const seconds = now.getSeconds();

It's also possible to modify the date or time information of a Date object.

Copy
const birthDay = new Date('1995-07-20');

birthDay.setFullYear(2000); // Change year to 2000
birthDay.setMonth(0); // Change month to January (starts at 0)
birthDay.setDate(1); // Change day to 1st

console.log(birthDay);
