A local student celebrated a day he'd been anticipating ever since he could count.
His 12th birthday.
Jack Greenlee turned 12-years-old on Wednesday, also known as 12/12/12.
Greenlee is a student at Adena Elementary in West Chester.
His class sang 'Happy Birthday', and his family celebrated the big day that night.
The school said Jack isn't the only one with a birthday to fall on an unlikely date.
Last year, a kid celebrated his 11th birthday on 11/11/11. What's more, another classmate celebrated turning 10-years-old on 10/10/10.
