Auction start and end times

I am looking for some opinions about the time for an auction's end. I apologize if there is a previous posting about this.
I am trying to find out if there is a particular timeframe where it seems the end auction price is higher. Is it better to start and end an auction in the am or pm. Is there any information about when the peak ebay shopping time is? I know people from all over the world are shopping but I though maybe someone has some thoughts or opinions.
I hope this isn't a foolish question. I am located on the east coast of the United States and looking to sell some game systems.
Thanks in advance for any help.

Here is a calendar that may help you choose :

Hope this helps some.

I've sold more on Saturdays and according to the calender this is a fair day, than some Sundays - maybe just a UK thing??
