Amazon Prime Day 2018 will take place on Tuesday July 17th with deals starting at midday the day before - Monday 16th. That’s all according to a Prime Day 2018 banner published on the Amazon UK website - presumably in error - and discovered by TechRadar this morning.

The 36 hour period for Prime Day 2018 makes it the longest Prime ‘day’ ever - providing final and clinching proof that Amazon cares not for the mental health or sleep patterns of TechRadar's deals team. It eclipses last year’s 30-hour period which started the evening before at 9pm and also breaks with Amazon’s recent tradition of running Prime Day on the second Tuesday in July.
