Amazon Prime Day is typically held once a year in mid-July, lasting about 2 days, but in recent years Amazon also holds additional sales events similar to Prime Day. In 2025, there were three major Prime Day-related events:
- The main Prime Day occurred from July 8 to July 11, 2025, making it Amazon's longest Prime Day at four days.
- Prime Big Deal Days, a similar Fall event, took place on October 7-8, 2025.
- Additionally, a Big Spring Sale has been introduced recently, making Prime Day-type sales happen about three times a year now.
Therefore, while traditionally Prime Day was annual in summer, Amazon now holds Prime Day-style events approximately three times a year—spring, summer, and fall—with the main Prime Day in July and other major sales events in March and October. These events are exclusive to Prime members and offer exclusive deals across many product categories.
