I have a credit card and I forgot how long it take for a credit card bill to come in the mail. I had a the criedit card for a least 25 days. I forgot if it will come in one month after the credit card came in?

They arrive monthly, yet another unwelcome friend..

At exactly what time of the month depends on the actual billing cycle that bank uses. Not all use the first of the month as a cycle starting point. Some start 2 weeks into the month. You could always call their customer service number on the back of the card and ask them when they normally send them out... and you add another couple days to a week to allow for it to arrive at your mailbox.
