answer:Eric Stackpole used a 150-foot parabolic dish located in the hills behind Stanford University to participate in the World Moon Bounce Day event. Time on the dish was donated by its operator, SRI International, and ham operators and engineers made temporary modifications to equip the dish for the Moon bounce. Stackpole sent his call name and "CQ" (meaning "anybody there?") from the dish, and around 2.5 seconds later, he heard his echo from the moon. Stackpole expressed his excitement at being able to send his voice from the moon without being an astronaut, and his participation was part of a larger global event involving approximately 100 parabolic dishes.

answer:The specific reason for choosing the date for the World Moon Bounce Day event is not mentioned in the given text material. However, it is mentioned that the event was held as part of a tribute to the Apollo 11 lunar landing, which occurred on July 20, 1969. Therefore, it is possible that the event was held close to the anniversary of the historic lunar landing. However, this is a speculation and not a confirmed fact.
