Build a Timesheet Calculator Web App
In this web development tutorial you will learn how to create a timesheet calculator web application using HTML CSS and JavaScript.
The web application will calculate the amount of worked hours, the amount of break time and then by subtracting from the work time the break time the application will calculate the amount of hours worked in one day.
You can add multiple day to this application, or even multiple weeks, or moths. At the end the application will calculate the total amount of hours worked in the specified time span.
