Aaron's Countdown

Aaron's Countdown is a small software application whose purpose is to help you count down the number of days, hours, minutes, and seconds until an important event, such as birthday, retirement, or graduation. The tool can be deployed on all Windows versions out there.

Drop it on pen drives

The utility is portable so you can store it on USB flash drives or other similar devices to carry it with you all the time. Plus, you may run it without being an administrator. You can also open it directly from the storage device.
Double-clicking on the executable file helps you gain access to the tool’s GUI. No installation process is needed. It’s easy to get rid of it if you no longer consider it useful because it does not leave entries in your Windows registry and generate additional configuration items. A simple deletion task does the job.

Minimalist design and a few configuration settings

Aaron's Countdown gives you the possibility to set the time in hours, minutes, and seconds, as well as pick a date from the built-in calendar. The calendar comes with basic features that allow you to jump to the previous or next month, and go to the next or previous year. In addition, you can set a user-defined title for the timer.
Tests have demonstrated that the application carries out a task quickly and without errors. It remains light on system resources so the overall performance of the computer is not affected. Plus, you can keep the timer on top of other panels.

Final remarks

To sum things up, Aaron's Countdown has to offer basic options for helping you work with a countdown timer, and is suitable especially for less experienced users. On the downside, there’s no support for advanced features so you cannot set up custom audio and popup notifications, and work with a stopwatch, just to name a few suggestions.
