On May 2, 2000, the decision was made to discontinue Selective Availability, ending the intentional restriction on civilian GPS accuracy and significantly improving GPS technology for public use. This date is recognized by geocachers as “Blue Switch Day.”
The first geocache was hidden on May 3, 2000, marking the beginning of geocaching—a journey full of innovation and experimentation. Today, there are 3.4 million geocaches in 191 countries.
If you are in the area, why not pop over and help celebrate the end of the day with an event. Attendees to the event will be eligible for the Blue Switch Day 2026 finder souvenir.
