Banks will be closed on the 4th of July as it is a national holiday.
Most banks were open on July 3rd, 2009; however, every bank I know of will be closed on the 4th of July. You should call up your individual bank to be sure but Bank of America is open on the 3rd, as is Wachovia, and Chase Bank.
Some banks may have limited hours on the 3rd. Call up your local branch to be sure, and everyone have a happy 4th of July weekend. Please leave comments if you know of any banks that will be closed or have modified hours on the 3rd. I know there are some banks that will be closed and I will update this post as I find out which ones are closed so be sure to check back here for updates.
