Amazon Prime Day in 2025 occurred twice: the main Prime Day event took place from July 8 to July 11, lasting four days, which was longer than the typical two-day event. Another Prime event, called "Prime Big Deal Days," happened October 7-8, 2025. This October event is a shorter, two-day sale period. Both events are exclusive to Amazon Prime members and offer significant discounts and deals on various products. Summary:
- Prime Day 2025 main event: July 8 to July 11 (four days)
- Prime Big Deal Days 2025: October 7 to October 8 (two days)
Prime Day traditionally is a midsummer event, but in 2025 Amazon introduced multiple sale periods under slightly different names across the year.
