Google Doodle: Father's Day

"Father's Day is a celebration inaugurated in the early twentieth century to complement Mother's Day in celebrating fatherhood and male parenting, and to honor and commemorate fathers and forefathers. Father's Day is celebrated on a variety of dates worldwide and typically involves gift-giving, and special dinners to fathers and family-oriented activities. In 2008, it will be celebrated on June 15th in most countries."
Google celebrates father's day from today because some countries like Austria and Belgium celebrate this day by June 14(Second Sunday of June). Google probably will keeps the doodle until tomorrow, so the most countries celebrate father's day by June 15.
