Those superstitious types who worried last year when the calendar read 06/06/06 will have something to smile about on Saturday.
Just get me to the church on time on 07/07/07 doctor
Many people who believe the triple appearance of the number 7 is triply lucky are falling over themselves to hold important events on 07/07/07, even getting hitched.
Brides and grooms who are looking for that extra bit of good fortune are apparently flocking to the altar on the numerically unique day.
Hotels, wedding planners, caterers and florists are trying their best to accommodate this flood of superstitious starry-eyed couples.
Joanne Orr, who owns a horse and carriage company in County Down, says it's one of the busiest periods she can remember.
"The demand for horses on this day is unbelievable. If only I had 20 horses I could have done 20 weddings," she said.
The demand is such that local wedding planner Tammie Rea, who normally has her horses provided by Joanne, has had to look much further afield.
"I am doing a wedding on Saturday and it has been really difficult sourcing everything I need," she said.
"All Joanne's horses are booked out, so I have had to get mine from Dublin."
Just as the number 666 and Friday the 13th are seen as being unlucky almost universally, the number 7's lucky tag is evident in many cultures.
In the Jewish tradition, the bride circles the groom seven times for a long and happy marriage, during the African holiday of Kwanzaa seven candles are lit to celebrate the seven days of creation, and gamblers in Las Vegas hit the jackpot with the slot machine combination 7-7-7.
However, the number 7 isn't as lucky in every tradition. Many Chinese people, for example, associate it with death.
