USPS aims to complete deliveries by 5:00 p.m. local time, Monday through Saturday.2USPS. Delayed Mail and Packages Your actual arrival time depends on where you sit on the carrier’s route. In December, and during other high-volume stretches, staffing and package loads can push the last stops past that 5:00 p.m. target.

When Saturday Delivery Doesn’t Happen
USPS observes 11 federal holidays in 2026, including New Year’s Day, Memorial Day, Independence Day, Thanksgiving, and Christmas, and doesn’t deliver regular mail on those days.7USPS. Holidays and Events When a federal holiday lands on a Saturday, USPS observes it on the preceding Friday for scheduling purposes.8U.S. Postal Service.

Amazon delivers on Saturdays in most service areas. Prime members get weekend delivery at no extra charge as part of standard shipping. Amazon uses a mix of its own network, USPS, and third-party carriers, so the experience varies by address, and Saturday drops can arrive late into the evening.
