Amazon posted a banner to its UK website Thursday declaring that Prime Day would be held July 16.

Amazon launched Prime Day, which boasts more deals than Black Friday, in 2015.

Amazon appears to have accidentally leaked the date of Prime Day, its heavily hyped midsummer sales event that boasts better deals than Black Friday.

The company on Thursday posted a banner to its UK website indicating that July 16 would be the date of the event, TechRadar reports.

In response to the report, an Amazon spokesman told Business Insider: "We announced last year that Prime Day would return; we don't have additional details to share yet."

Amazon launched Prime Day in 2015.

More than a dozen other major retailers have since started taking part in the event by offering their own massive sales events to counter Amazon.

In addition to running their own promotions, some retailers promised last year to price-match Amazon's Prime Day deals.

Most of Amazon's deals on Prime Day are better than what shoppers might find on Black Friday, the biggest shopping event of the year, according to BestBlackFriday.com.

The website analyzed Amazon's deals on Black Friday and Prime Day and found that in 2016, 77% of Prime Day prices were better than comparable deals offered on Black Friday.
