A year is a unit of time that is roughly equal to the time it takes the Earth to make one complete circuit around the sun, which is 365 days, 5 hours, 49 minutes, and 12 seconds of mean solar time.
But a light-year is not a unit of time; it is a unit of distance. It is equal to the distance traveled by light through a vacuum in one year, which is about 9.5 trillion (9.5E12) kilometers or 5.9 trillion (5.9E12) miles.

Is the earth 4.5 American billion years old or 4.5 English billion years old?
Though it pains me to admit it, the American definition of a billion - ie; one thousand million or 1,000,000,000 - is considered to be the 'correct' definition, as the British definition - ie; one million million or 1,000,000,000,000 - is not in line with our ten-based counting system.As such, scientists tend to favour the American definition, and it can be assumed that whenever you read the word billion in a scientific or technical text, it refers to that one.
