Dynamic shipping date based on customer’s order date

want to display an exact estimated shipping date (e.g. "Ships on July 13") that updates automatically based on when the customer places the order.

For example, if a product has a 5-day lead time and a customer orders on July 1st, the message should say “Ships on July 6th.” If another customer orders on July 3rd, it should say “Ships on July 8th.”
