How we can create a dynamic calendar using only jQuery without any plugin? Solution: See this jQuery Dynamic Calendar Program With CSS, Basic jQuery Calendar.
Previously I have shared an animated HTML CSS JS Calendar program, but this is a dynamic calendar based on jQuery. Basically, a dynamic calendar is completely created with JS or JS library. When we don’t create HTML layout like table or list for creating the calendar, then its called a dynamic calendar. This specific calendar is completely created by jQuery, but the fact is jQuery adding here HTML elements dynamically.
Today you will learn to create Basic jQuery Calendar. Basically, there is a simple calendar with week names in the heading section and dates in the table body section. On the middle top you will see month and year information, and on the top two sides left and right there are two buttons for next and previous month. These two buttons have next and previous month’s name where you can select your month and year, not only next-previous text.
So, Today I am sharing the jQuery Dynamic Calendar Program With CSS. There I have used HTML to create only a few elements, CSS for styling, and jQuery for complete program and creating all calendar items. This is a complete calendar with all basic requirements, you can customize the style and functions of its. You can use this calendar program on your website or project.
If you are thinking now how this basic calendar actually is, then see the preview given below.
Preview Of Basic Calendar UI
See this video preview to getting an idea of how this basic calendar looks like.
Now you can see this program visually, also you can see it live by pressing the button given above. If you like this, then get the source code of its.

jQuery Dynamic Calendar Source Code
Before sharing source code, let’s talk about it. First I have created the header section using HTML <header> tag and div outside the header for calendar items. Inside the header, I have placed two buttons and two headings, buttons for Next and Previous months and headings for show Year and Month. Also in the HTML file, I have linked other files like CSS, JS, jQuery CDN.
Now using CSS I have placed all the items in the right place, as you can see in the preview. With CSS first I gave basic values like size, position, margin, padding, etc to all the elements. There I have styled all the elements which are created using HTML and jQuery also. There I have hidden the calendar on an extra small screen, because it breaks the layout you need a 400px or above screen width to see the program.
jQuery handling here the whole functions in the program. First I stored all weeks name, dates 1 to 31, full-year name, and short year name in the array. Then I placed the dates using for loop for() command, it makes the work easier. After that, created HTML elements dynamically and used if{} else{} statements to declare conditions.
Left all other things you will understand after getting the codes, I can’t explain all in writing. For creating this program you have to create 3 files. First file for HTML, second for CSS, and the third file for JavaScript. Follow the steps to creating this program without any error.
index.html
Create an HTML file named ‘index.html‘ and put these codes given below.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 |
