Display the shipping date in the shopping cart according to specific criteria

Hello, We want to display an approximate shipping date in the customer's shopping cart, called in french "Date approximative de livraison". This date will be scheduled according to the order confirmation date and the shipping area (split into 2 zones): - ZONE 1 : La Réunion (Nord & Est) - ZONE 2 : La Réunion (Sud & Ouest) These two zones are already integrated in the woocommerce. The shipping date to display must be set according to the following criteria. Let's take a case to understand: We are in week 3 (W3). - For the customers from ZONE 1: Shipping will be on MONDAY of the next week (W4) > If the order is placed between Monday and Thursday inclusive of the current week (W3) > If the order is placed on the Friday of the past week (W2) - For the customers from ZONE 2: Shipping will be on TUESDAY of the next week (W4) > If order is placed between Monday and Friday inclusive of the current week (W3) For orders placed on Saturday and Sunday (W3), the final order date will be considered from the next Monday at 08:00 (W4).
