Design Matters.
We’ve incorporated the best thinking in Time Management into our planner design. More than a calendar, our intuitive page layouts and unique forms will help you to organize better and manage your time more effectively.

Results Matter.
A University of Munich Study found that users who began using our system increased their efficiency by 18.4% while reducing their stress 13%. For most of us, that’s like finding an extra 1-2 hours per day.

Recognition Follows.
Winner of the prestigious European iF award for excellence in design form and function, our system has also been made part of the permanent collection at the Smithsonian Cooper-Hewitt National Design Museum.



Since 1981, TDI has been providing this award-winning day planner and time management system to major corporations in North America and Europe. Worldwide our system has been used by more than 1 million users in more than 20 countries and 10 languages. Not just another day planner, our intuitive design is based on the best thinking in time management and will help you get better organized.

Not all day planners are the same. Every other planner is little more than a calendar with a place for notes and To Dos. Not a lot of thought went into the design so you don't get much out of it. The problem with these planners is that any critical information is captured on a calendar page forcing you to either rewrite information over and over again as the days go by or flip back through months of pages to find what you need.

Never re-write your To Do list, easily track items you're waiting for from others and keep your list of goals at top of mind with our Activities Checklist. The most important form to ever be developed for day planners is a simple but ingenious idea.

Capture and organize information in our DataBank™ section of the planner. Another simple idea: keep notes organized by topic, not date.

Expect more from your planner. A good day planner should encourage smart organization skills simply and intuitively. View a short flash presentation to see how our system does just that. Adjust your volume and click here.
