Date Object

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


Creating a Date Object​

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

Creating a Date Object
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.


Setting a Specific Date and Time​

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

Setting a Specific Date and Time
const birthDay = new Date('1995-07-20');
console.log(birthDay);

Retrieving Year, Month, Day, Hour, Minute, Second​

You can retrieve specific information from a Date object.

Retrieving Year, Month, Day, Hour, Minute, Second
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();

Modifying Date and Time​

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

Modifying Date and Time
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);
