What do you think is the best time for an eBay auction to begin ?

Personally, I begin all mine at 5:30 pm. This way they END at 5:30 p.m. either 5, 7 or 10 days later.

This works for me because if they are ending at 5:30 pm on the west coast they are ending at 8:30 on the east coast.
This is after people have gotten home and ...gives them some time before going to bed...to bid.

I usually start mine about an hour later 6:30 Pacific because alot of us in California are still commuting around 5:30 cuts out a big bunch of potential last minute bidders/snipers.
