Day-Timer

Day-Timer is an American manufacturer of personal organizers and other paper-based time management and organizational tools. The company was founded in 1951 in Allentown, Pennsylvania, and ultimately relocated to neighboring East Texas, Pennsylvania, in the 1960s as its sales and product popularity grew.

In the early 21st century, however, the company suffered from emerging competition from electronic devices with similar functionality. In 2012, it ultimately decentralized its offices across several states while continuing to publish its paper-based products.
