Prime Day is a shopping event created by Amazon that is exclusive to Amazon Prime members. During Prime Day, Amazon offers deals on a wide range of products from top national brands and small businesses across categories such as fashion, electronics, toys, and home. Prime Day typically lasts for two days and is held annually. The event was created to celebrate Prime members, and the first Prime Day event was held on Amazons 20th birthday on July 15, 2015.

To participate in Prime Day, one must be a member of Amazon Prime. However, anyone can participate in Prime Day by signing up for an Amazon Prime free trial or paid Prime membership. During Prime Day, Amazon offers exclusive deals on products, and to qualify for a Prime Day offer, one must place the order when the deal is live on Prime Day and meet any qualifications listed in the deal.

Prime Day is not a one-time event, and Amazon has held multiple Prime Day events in a year. For example, in 2023, Amazon held a fall sale event called Prime Big Deal Days, which followed a similar timeline to the mid-October Prime Day event from the previous year.

In summary, Prime Day is a shopping event created by Amazon that offers exclusive deals on products to Amazon Prime members. The event is held annually and typically lasts for two days. Anyone can participate in Prime Day by signing up for an Amazon Prime free trial or paid Prime membership.
