JavaScript provides a number of methods for getting information about a date object. These methods can be used to get the day of the week, month, year, hours, minutes, seconds, and milliseconds.
Creating a Date Object
Before you can use any of the JavaScript get date methods, you need to create a Date object. There are two ways to do this:
Use the new Date() constructor. This will create a Date object with the current date and time.
Pass a string representation of a date to the Date() constructor. This can be useful for creating Date objects from dates that were stored in a database or read from a file.
Get Date Methods
The following table lists the most common JavaScript get date methods:
| getDate() | Returns the day of the month (1-31). |
| getDay() | Returns the day of the week (0-6, where 0 is Sunday). |
| getMonth() | Returns the month (0-11, where 0 is January). |
| getFullYear() | Returns the year. |
| getHours() | Returns the hours (0-23). |
| getMinutes() | Returns the minutes (0-59). |
| getSeconds() | Returns the seconds (0-59). |
| getMilliseconds() | Returns the milliseconds (0-999). |
Examples
The following examples show how to use the JavaScript get date methods:
// Create a Date object with the current date and time.const now = new Date();// Get the day of the month.
const day = now.getDate();// Get the day of the week.
const dayOfWeek = now.getDay();// Get the month.
const month = now.getMonth();// Get the year.
const year = now.getFullYear();// Get the hours.
const hours = now.getHours();// Get the minutes.
const minutes = now.getMinutes();// Get the seconds.
const seconds = now.getSeconds();// Get the milliseconds.
const milliseconds = now.getMilliseconds();// Log the results to the console.
console.log(`Today is ${day}.`);
console.log(`The day of the week is ${dayOfWeek}.`);
console.log(`The month is ${month}.`);
console.log(`The year is ${year}.`);
console.log(`The time is ${hours}:${minutes}:${seconds}.${milliseconds}.`);
Using Get Date Methods in Real-World Applications
JavaScript get date methods can be used in a variety of real-world applications. For example, you could use them to:
Create a calendar application.
Calculate the number of days between two dates.
Calculate the age of a person.
Convert a date from one format to another.
Display the current date and time on a website.
Conclusion
JavaScript get date methods are a powerful tool for working with dates and times. By understanding how to use these methods, you can write more complex and sophisticated JavaScript applications.
