I have eleven credit cards. I also maintain about 45 active accounts in You Need a Budget (great budgeting software you should check out – it’s free for students!), so I’m no stranger to managing multiple accounts. But even though I can manage all of those accounts without undue burden on myself, even I would drive myself crazy if I didn’t consolidate my credit card due dates to be on or around the same day, and in all likelihood I’d probably miss a payment. It makes your cash flow management easier when you have one consolidated outflow. Some banks let you change this online, but most of them will require a phone call. Typically you end up with one longer statement cycle when you do this, as opposed to one normal length cycle and one short cycle.
