How to Create an Analog Clock using JavaScript

Back to Coding, Here is the short description about creating an analog clock using HTML, CSS & JavaScript with source code. To execute the same program you need to copy those codes, it works fine. If you want to change something and modify yourself then you need to know some function.

Which is setInterval(); for evaluates an expression at specified intervals, setTimeDate(); for sets Calendar’s time with the given Date, getHours(); getMinutes(); getSeconds(); for getting hours minutes seconds. And the last one div.innerHTML for set value to any division.

To complete this program with debugging free code you have to create three files. The first file is to HTML and the second file gonna be CSS for design part and the third file JavaScript for function-related,

index.html

Create an HTML file named ‘index.html‘ and put those codes given below.
