How long would it take to count a mole of atoms?

Was a bonus question on my chem test today.

"If you could count two atoms every second, how long would it take you to count a mole of atoms? Assume that you counted continually 24 hours every day. How does the time you calculated compare with the age of Earth, which is estimated to be 4.6 x 10^9 years old? Convert your answers to days."
