By the way the Date Range tool uses what is known as a 'Sticky Setting' - which means that it stays where you set it, until you actively set it to something different. This is true, even if you log out and then back in - or return to your account after several days.
So if today, 4/25, you set it to 'Yesterday', it'll give you stats for yesterday 4/24.
Then, if you then log in next on Thursday 4/28, it'll still be set to 'Yesterday' (unless you've changed it) which would be 4/27.
Because many advertisers forget they've set the date range to a particular day, I often advise advertisers to check the date range to which they're set first thing upon entering their account - each and every time they log in.
After all it's pretty hard to get useful information from one's statistics without knowing for what period of time those statistics are for. ;-)
