when I made a $20,000.00 charge to my starwood. It always closes on the 29th so I waited to pay some property taxes until 1am on the 30th. Low and behold the one and only month they changed the cycle close date to the 30th. So I agree with the above poster they must have something in their system that trys to grab high charges and delay the cycle date if they can on their credit card product.
