How to Add a Custom “Estimated Delivery Date” in WooCommerce Using Hooks

Showing an estimated delivery date helps reduce customer uncertainty and increases trust during checkout.
Instead of guessing when an order will arrive, customers see a clear timeframe before purchasing.

In this tutorial, you will learn how to display a dynamic estimated delivery date in WooCommerce using hooks.

Why Estimated Delivery Dates Increase Conversions

Uncertainty is one of the main reasons customers abandon carts.
Clear delivery expectations remove doubt and improve confidence.

• Reduces cart abandonment
• Builds trust with customers
• Improves transparency
• Encourages faster purchase decisions

The WooCommerce Hook We Will Use

We will use:

woocommerce_single_product_summary

This hook allows us to display delivery information directly on the product page.

Example Code

Add this code to your theme’s functions.php file or a custom plugin:

add_action('woocommerce_single_product_summary', 'estimated_delivery_date', 25);

function estimated_delivery_date() {

    $min_days = 2;
    $max_days = 5;

    $min_date = date('F j', strtotime("+$min_days days"));
    $max_date = date('F j', strtotime("+$max_days days"));

    echo '
';
    echo ' Estimated delivery: ' . $min_date . ' – ' . $max_date;
    echo '
';
}

How It Works

• Calculates delivery range based on current date
• Displays estimated delivery window on product page
• Updates automatically every day

Customization Ideas

• Different delivery times per shipping zone
• Add countdown for same-day shipping
• Show delivery dates on cart and checkout pages
• Adjust dates based on product stock location
