There are a number of celebrity birthdays during the "Frog Days Of Summer", and today President Barack Obama celebrates his 51st birthday. On this day in 1961, President Obama was born in Honolulu, Hawaii.

Here's a brief bio, courtesy of www.whitehouse.gov :

"Barack H. Obama is the 44th President of the United States and was born in Hawaii on August 4, 1961.

He was raised with help from his grandfather, who served in Patton's army, and his grandmother, who worked her way up from the secretarial pool to middle management at a bank.

After working his way through college with the help of scholarships and student loans, President Obama moved to Chicago.

He went on to attend law school, where he became the first African-American president of the Harvard Law Review. Upon graduation, he returned to Chicago."

Other famous people celebrating birthdays today include:

Billy Bob Thorton, Jeff Gordon, and former NFL Hall of Famer John Riggins.

So, we say happy birthday, Mr. President, and happy birthday or anniversary to any of you who are also celebrating.
