How many days are viewers of a cursed videotape given to live in the horror film "The Ring"?

In "The Ring" (2002), a cursed videotape is created by Sadako Yamamura as a means of transmitting Sadako's curse to the rest of the world. The tape is used to directly spread a deadly virus. When other copies are made, they turn the original curse into a supernatural one. The viewers of Sadako's videotape have just seven days to copy the tape and show it to someone else, otherwise, Sadako will kill them.

The videotape is an item with no apparent label on the tape. When an analysis is done, there is no sign of who recorded it. The tape plays fine in a VCR; copies of the videotape can be made. By making copies, this allows more cursed items to exist and circulate. If anyone watches a copy or the original, the effects of the curse is exactly the same.

The video itself shows a panorama of odd and disturbing images relating to Sadako's past. Most images are in black and white. The first scene is a shot of Heihachiro Ikuma looking down at Sadako. She had been thrown into a well. Next Shizuko Yamamura appears, combing her hair in a mirror. Sadako walks in on her. Shizuko's mirror briefly disappears and one showing Sadako appears. Shizuko reappears looking towards Sadako. Then, a newspaper article about Shizuko predicting the eruption of Mount Mihara appears. Kanji letters, which are used in the Japanese writing system, begin to float about and spell the word 'eruption'. People are then depicted crawling on the floor; they are dying in the aftermath of Mount Mihara's eruption.
