I have noticed that the estimatedDeliveryTime response from the POST /orders does not use isWeekend().

Yes, it does not. But the "skipping weekends part" was an exercise. Lesson 15 Exercise 15m.

@a10n-jsd use this code

const matchedOption = findDeliveryOption(order.orderTime, productDetails.estimatedDeliveryTime);
console.log(matchedOption);

let deliveryDate = 'undefined';
if(matchedOption){
       deliveryDate = calculateDeliveryDateFrom(order.orderTime, matchedOption);
}

 <div class="product-quantity">
     Quantity: ${productDetails.quantity}
 </div>

// all this code for skipping weekends from product-delivery-date
// to skip weekends we need deliveryOptions.deliveryDays 
// but the products we get from backend doesnt have deliveryOption, and we cant change backend
// so here is the code for finding an deliveryOption, which we can use in our function

function countDaysBetween(startDate, endDate) {
    // .diff is built-in method of dayjs which calculates tha difference between two dates in days
    return dayjs(endDate).diff(dayjs(startDate), 'day');
}

function findDeliveryOption(orderTime, estimatedDeliveryTime){
    const daysBetween = countDaysBetween(orderTime, estimatedDeliveryTime);
    return deliveryOptions.find(option => option.deliveryDays === daysBetween) || null;
}

Alternate version of calculateDeliveryDate(). Put this code in deliveryOptions.js

export function calculateDeliveryDateFrom(orderTime, deliveryOption){
    let orderDate = dayjs(orderTime);
    let daysAdded = 0;

    while(daysAdded < deliveryOption.deliveryDays){
        orderDate = orderDate.add(1, 'day');

        //skip weekends: 0 = Sunday, 6 = Saturday
        if(orderDate.day() !== 0 && orderDate.day() !== 6){
            daysAdded++;
        }
    }

    return orderDate.format('MMMM D');
}

this calculates not from current date but the day we ordered
