Is there a best time to call HR?

I did some research, this is from an article from The Bagg Group 

"The best times to call are first thing in the morning, between 8 am. and 9 am and end-of-day between 4 pm and 5 pm."

I called a potential employer, between 8 and 9 am. During my call, I received 2 calls from other potential employers. 👍
