Yes, during checkout the "Preferred delivery date" field is available, where you can indicate the date on which you would prefer to receive the goods. This is an indicative preference: fluid-hub takes it into account when planning the shipment, but the actual times depend on the availability of the goods and the courier's schedule.
For information on estimated delivery times by destination, visit the Shipping page. To monitor the status of your shipment, read How can I know the status of my order? For other preferences to communicate to the courier, read Can I enter notes for the courier or preferences on the delivery?
