They don't.
Explain why astronomers use white dwarfs to date the universe?
They use them to determine the distances of galaxies through the "standard candle" called a type Ia supernova, which are always caused by white dwarfs. They are so bright that they will outshine the galaxy they are in. Because the universe is expanding, the greater a galaxy's distance from us, the greater its red shift. If we know that a certain event has a standard brighteness and we know that the red shift increases at a predictable rate as well, we can use these type Ia supernovae to measure how far off these galaxies are and from this, how long they've had to travel away from a common centre. It is estimated that the universe is about 13.8 billion years old.

How old are white dwarfs?
White dwarves are essentially the ashy remains of stars that have used up almost all of their fuel. This is accomplishedd by bing around for a long time. Astronomers have identified white waves that are 11- to 12-billion-years-old (and only 100 light years away from Earth). That date would make them almost as old as the universe, By contrast our sun is "only" 7 billion years old.
