Sure, there are phone apps you could use, or just staring the clocks etc.
Want something quick and easy?
Google lets you create/use a stopwatch and countdown watch on your brower!
Try this search:
www.google.com/search?q=google+countdown
and you’ll see from there… you can schedule out 5 minutes here, 20 minutes there….
… ensuring you are as much planned as you can be.
How is this useful? Well, it sure surprised me when I learned about the Google countdown timer itself – great for alerting me to when a webinar was about to start or when something was about to close down (and I knew I’d be awake when it happened).
You can even set it up in Google Calendar like so:

(although that seems like more of a doomsday counter. 
)
Other (more marketing) uses you can share with your colleagues, friends (or even blog about) can be found at:
