Jon and Lisa Hall did not realize 12 years ago that their fourth of five children would have a birthday anomaly.
Their daughter, Mackenzie Hall, will celebrate her 12th birthday Dec. 12, 2012.
"We didn't realize it until last year when she had her 11th birthday," Mrs. Hall said. "Then we suddenly realized she'd be 12 years old next year, on 12-12-12."
To commemorate the rare occurrence, the family is planning an out-of-the-ordinary birthday party for Mackenzie themed to the CBS reality show, The Amazing Race.
Instead of flying planes across Asia and Europe, delivering bamboo in India or playing a street-corner organ in Amsterdam, Mackenzie and her friends will use Cemetery Road as their stage.
They will receive instructions at the Hilliard branch of the Columbus Metropolitan Library, then visit several locations to complete their orders, including Sawchuck Jewelers, Dave & Buster's and Iacono's Pizza.
Although she admitted she is not a fan of the show, Mackenzie said she is looking forward to the birthday celebration.
"It will be a lot of fun with my friends," she said.
Her father said he wants her birthday to the "the best day of her life" and is planning a special activity at noon, building on the theme of "12."
"I hope the principal at (Hilliard Station Sixth Grade School) will announce her birthday during daily morning announcements so the whole school can share in it," Mr. Hall said.
Mackenzie has one brother and three sisters. She is a Girl Scout and plays the saxophone in the band at Hilliard Station.
She also plays volleyball and softball for non-school athletics organizations.
