In the United States, DHL does not deliver on Sundays. However, DHL does deliver on Sundays in some countries where conducting business on Saturdays and Sundays is customary.
In general, DHL measures its services in terms of business days. Therefore, packages sent next day delivery on Friday are delivered on Monday. There are a couple of options, however, for time-sensitive or emergency deliveries. In some cases, it is possible to arrange fastest-point jet service with the company to ensure the package reaches its destination any day of the week. Because this is considered a premium service, it commands premium prices.
