A woman born weighing 6lbs 6oz on 6 June at 0600 BST, and who is 66 on 6/6/06, is refusing to drive on her birthday to help avoid accidents.
June Dumas said she would not be driving on her birthday
Retired East Sussex nurse June Dumas said despite her birthday being on the day of "the number of the beast" she had grown less superstitious with age.
"[But] I've had a few nasty accidents in the past," she said.
The 666 phenomenon comes from several popular versions of a disputed passage in the Book of Revelation.
The profile of its connection with the Devil was raised by the cult 1976 horror movie The Omen.
Mrs Dumas, born at Brighton General Hospital in 1940, said her late mother, who she says was a psychic, had always warned her to "watch herself" when she turned 66.
The woman from Hove said she had become less superstitious as she got older, but she still saluted single magpies, and avoided walking under ladders.
She said: "It's a bit eerie and I'm not sure what to make of it all, but I plan to take things really easy."
And Mrs Dumas added that she had planned to do all her jobs on Wednesday so she did not have to use the car on her birthday.
Mrs Dumas said she had come through her 26th birthday in 1966 without any problems and added: "I hope [this birthday] passes just as well."
A modern-day remake of The Omen has its worldwide cinema release on Tuesday.
Mrs Dumas will celebrate her birthday with a visit to a casino with her partner, Paul, where she said she expects to lose a fortune.
"I used to be a superstitious person but as you get older you tend to think that what will happen will happen," she said.
