7’s Day is always on the same date, which of course is July 7th, aka 7/7. The date is to celebrate all things RX-7 related, Mazda’s lovechild that was born from the rotary engine. The event has its roots everywhere around the world but is more predominant in different parts of Japan, and the United States. All around the world, on the same date, everyone with an RX-7 of any generation get together for one day to burn off some of that carbon deposit.But it’s not just RX-7’s. Any type of rotary powered car typically comes out for 7’s day including RX-8’s, Cosmos, Caterham’s, and swapped cars found in a ton of Starlet’s, Datsun 510’s, and Miatas. But that’s not to say non-rotary powered cars aren’t welcomed, that’s right, your LS/2JZ/K20/SR20/1JZ swapped RX-7’s are also welcome!
