Does the day I activate my credit card affect my due date?

I have had a Discover Card for many years and have recently received a new set of cards with a new account number because of an account breach. If I want to keep a similar statement closing date and payment due date should I activate the new cards at a specific date during the month?|||it does not matter when you activate the card. if you want a different due date you can call discover and request they change the due date.|||No. Your account is already open. Card activation is just a security feature to defeat possible card theft.|||Discover allows you to pick the date you would like your account to be due. Call them and tell them what date you would prefer. There will usually be one short period, (for example if you are currently set up for payment on the 30th, and you wish to change to the 15th, and you change it today, then you will have a statement due April 30th, and the next statement will have May 15th.)
