Jennifer Flynn thanks her lucky stars that she began dating Shawn Casinader seven years ago, on the seventh day of the seventh month of the year. The couple (both born in 1977) met while working as customer-service representatives at a Boston dot.com company.

So could there be any more auspicious day than 7-7-07 on which to start their married life?

“We got engaged in December ’05, and we were thinking of getting married last year, and then realized that 7-7-07 was on a Saturday,” said Flynn on Friday, barely 24 hours before she was due to exchange vows.

The couple moved to Texas last year, but booked their 7-7-07 wedding date at the Kinney Bungalow at Sunset Farm, in Narragansett. Flynn, who spent her summers in Narragansett, recalled that the Kinney Bungalow setting “has the most beautiful sunset light.”

Flynn was happy enough to book her favorite spot on a day that the couple already considered their anniversary. Then she learned that couples the world over were choosing 7-7-07, for luck. The lineup of sevens tripled the significance of a number that for many is imbued with magic, mysticism and good fortune, from its Biblical reference to the seven days of creation, to the ancient Babylonians who revered the seven sacred planets.

Said Flynn, “We were completely surprised about how popular the date was.”

Shirley A. Eastham, events coordinator for the turn-of-the-century Kinney Bungalow, said, “I had quite a few people ask about it, but Jennifer had booked it quite early. I got a lot of ‘Oh drat’ kind of responses. As people were asking [for that date], it just occurred to me over time, ‘Gosh what a great date! Everybody wants it.’ ”

Whether just another day, or “the luckiest day of the century,” as many dubbed it, the triple 7s set off a sort of fever in many parts of the world.

Subhash Kakkar, president of the Banquet Halls Association of Dehli, in India, noted that though this week was not a peak time for marriages, banquets across the capital were booked. Superstitious couples in Australia who wanted to marry on 7-7-07 overwhelmed marriage registries.

The Six Flags amusement park chain hosted seven “Thrilled Ever After” wedding receptions at 7 a.m. The Ritz-Carlton New York created a “Lucky No. 7 Wedding Package” for $77,777.

The Tropicana Casino and Resort in Atlantic City offered a $7,777 package. Lottery officials braced for a sell-out of 7-7-07 picks.

Kara Richards, director of sales and marketing at the Venus de Milo restaurant, in Swansea — the site of hundreds of weddings each year — said that people began calling two years ago to reserve that date.

Kate Vivian, coordinator for The Towers in Narragansett, where at least 80 couples are married each year in a grand room overlooking the ocean, said she turned away “at least seven or eight” people who wanted to book that date.

Couple after couple took turns in the Rose Garden yesterday at Roger Williams Park, in Providence.

The wedding of Jennifer Flynn and Shawn Casinader, who is Sri Lankan, spoke to simple elegance that blended American and Sri Lankan traditions. Bowls full of pale lilac and peach orchid petals decorated the entry hall of the Kinney Bungalow, a circa 1899 architectural jewel designed in the British Colonial East Indian style.

Upstairs, red roses served as centerpieces at every table. Tiny boxes with Sri Lankan wedding cakes, stamped “Jennifer and Shawn,” and “7-7-07”, were placed at each place setting.

Bride and groom said their vows beneath a bower draped with red roses. Jennifer Flynn became Jennifer Flynn Casinader, and the couple kissed for the first time as husband and wife.

And as luck would have it, the sun sparkled.
