is sunday a business day for usps

Is Sunday a business day for USPS depends on the type of service being used. While USPS generally does not operate on Sundays for most standard services, they do offer limited services, such as Priority Mail Express, which guarantees delivery on Sundays, including holidays. Other USPS services, such as regular mail or packages, are typically not delivered on Sundays, but the tracking status may still show updates if the package is in transit or awaiting delivery. It’s important to check your specific shipping method and confirm whether it includes Sunday delivery or if you will need to wait until the next business day for delivery.
