when was prime day 2025

Amazon Prime Day was first held on July 15, 2015, to celebrate Amazon's 20th birthday. The inaugural event lasted 24 hours and was available in 9 countries. Since then, Prime Day has grown into a major global shopping event, often lasting multiple days and taking place typically in the summer each year. The exact dates vary by year. Recently, in 2025, Amazon held two Prime Day events: one summer event from July 8 to July 11, 2025, and another event called Prime Deal Days from October 7 to October 8, 2025. The summer event in 2025 was unusually extended to four days, while the October event lasted two days.
