Amazon's Prime Big Deal Days for October 2025 will run for two days, specifically October 7 and October 8, lasting 48 hours. This fall event is shorter than the July Prime Day event, which extended to four days this year. However, in Canada, the October Prime Day event uniquely lasts four days, from October 7 to October 10, 2025. For the U.S. and most other regions, the October Prime Day is a two-day sale event.
