When I was asked to find a suitable timer for a technical talk event with a limit on the talk time alloted for the speaker, my search did not yeild any useful results. Most of the solutions I came across was either too bloated, platform specific like for Windows or Linux, needed connectivity online like in TED Countdown.

After without much success, I decided to replicate the TED Countdown Timer which was very minimalistic and met most of the requirements. However it lacked the ability to host talks above 20 minutes (which is the hard limit on most TED talks) and it still needed to load from a web page which needed connectivity.

The aim of this little project is to have an offline solution which can be hosted in a system which has no internet connectivity and have the ability to host talks which are more than 20 minutes in length.

I personally felt that having an interface that most users are familiar with will also be helpful, hence the choice for TED's Countdown Timer.

• Timer is no longer restricted to 20 Minutes maximum, has been extended to 60 Minutes.

• The interval increments are 5 Minutes, instead of 1 minute, this was done to avoid the rather long drop down list.

• Removed the Google Analytics and related scripts.

• "Un-minified" the CSS file.

• The files have been neatly organized into the proper folders.

The Countdown Timer is free to use, and can be accessed through any Web browser. Using Chrome’s Presentation Mode allows you to focus only on the timer. If you want to use the Timer like an app on your mobile device, tap on the share icon (iOS) or menu button (Android) and select “Add to Home Screen.”

You will need to put the files in a Web Server (like Apache for example) or download these files to your computer, and then access the index.html via browser. This will load the Countdown Timer UI.

To start the Timer, select the duration of your talk (choose any length from 2 to 60 minutes). Next hit "Start now" to begin the countdown immediately, or "Start in 10 seconds" to give yourself time to get ready.

For a less distracting countdown, the Timer initially displays minutes only — for example, a 15-minute talk will flash “15” to start, then display “14” for the next 60 seconds, then “13,” and so on. The dots along the bottom show your progress through each minute (each dot represents six seconds).

The Timer will switch to a second-by-second countdown at 90 seconds. If you go over your chosen time, the Timer screen will turn red, flash "OVER TIME," and begin counting up.

To pause the Timer, use the button in the lower right corner; if you're on a laptop or desktop machine, move your mouse to make the pause button appear.

If you spot a bug or just need help, feel free to raise a ticket and we shall respond as fast as possible.
