If you’re a dutiful credit-card user, you pay off your credit-card bill every month. You’re probably used to paying it off whenever the card company says it’s due—maybe the 12th of the month, or the 20th, or whatever.
But did you know that the monthly due date is up to you?
You might want to shift it to the first of the month, to make it easier to remember. Or you might want to shift your Visa card so its due date is separated farther from your AmEx due date. Or maybe you want them all due on the same date, for simplicity.
