Is it possible visiting Huangshan in one day?

We are thinking about visiting the mountain from Hangzhou in one day.
We could take the first bus to HS, visit the mountain, go down and return to Hangzhou. Is it possible?
I am able to find the bus schedule from Hangzhou to HS but not the other way.
If it's not possible, what is the best option? Arrive at Huangshan in the morning, sleep at Huangshan and go back to Hangzhou the day after?
Thank you very much.
