First of all, a light year is not a measure of time. It is a measure of distance. A light year is the distance light travels in a year.
Second, it depends on the distance of the star. The closes star to us is the sun. Light from it takes 8 minutes to reach Earth. The next nearest is Proxima Centauri, from whigh light takes about 4 years to reach us. The stars we see at night are a few hundred light years from us. However, the vast majority of stars in the universe are to far away to be visible to the naked eye. The most distant stars are billions of light years away.
