How to Add jQuery Countdown Timer Widget in Blogger blogs

Have you ever thought of adding a Milestone Countdown timer widget to your Blogger Blog? From time to time we bring change to our blogs or website, maybe it's your blog’s anniversary, new product launch or something else. A countdown timer can always keep your readers updated about something that’s going to happen. This could turn out to be so helpful in creating magnificent interest among your readers because not every day you release a new product. Well in this article, we will show you how to add a countdown timer widget in your Blogger posts, pages, sidebar and home page.
If you are using Blogger.com, then you know there are no such default countdown gadgets. Therefore, we have to integrate it by using some third-party plugins and coding. For that reason, we have developed a simple yet essential count down plugin for Blogger that functions just like other WordPress plugins available on the web. This plugin is called the MBL Countdown timer.




The First thing you need  to login into your blogger account and go to Template >> Edit HTML. Now in the template coding search for </head> an just above it paste the following piece of Javascript and CSS coding. (We are not adding the CSS code separately because it will save your time and would give fair enough same, productive results).

After installing the JavaScript and CSS Paste this code anywhere you would like to display the Countdown widget. For example if you want to display it somewhere in the sidebar then, go to Blogger >> Layout >> Add a Gadget > Add HTML/JavaScript >> And paste the following code in the text area. Same goes with Posts and pages.

<div id='countdown_def' class='timerArea' ></div>
<script>$(document).ready(function() {$("#countdown_def").countdown( {dateEnd:'11/12/2014 18:01:30',format:true,callback:function(){alert('Def Ready')}},{timezone:false,offset:0});});</script> 

Remember: Do not forget to customize the date and time of your counter widget because this would be the main thing which will operate it. From the above code, search for11/12/2014 18:01:30 and replace it with your personalized date and time for the timer widget.
