What Are Mailing Business Days and How to Count Them to Ensure Packages Get Delivered on Time

Ensuring timely delivery of packages hinges on a clear comprehension of mailing and shipping business days. This comprehensive guide delineates what constitutes a business day for USPS and other major carriers, elucidates how transit days are counted, and provides invaluable tips for circumventing delivery delays.

What is Considered a Business Day for USPS Delivery?

The operational schedule of the United States Postal Service (USPS) spans Monday through Saturday. However, discerning what qualifies as an official business day is essential.

Weekdays from Monday to Friday are universally acknowledged as standard business days for USPS. During this timeframe, all regular USPS mail services remain operational. Saturdays, however, are treated differently. While some USPS services are available on Saturdays, it is not a full business day. Conversely, Sundays and major holidays hold no business status for USPS. On these days, no regular mail services are provided. Hence, the general delineation is that Monday through Friday constitute full USPS business days, Saturday is considered a partial business day, and Sundays/holidays are excluded entirely. Acquiring clarity on this differentiation is pivotal for accurately tracking USPS transit days.

Does USPS Deliver Mail on Saturdays?

USPS does offer limited mail services on Saturdays, including the delivery of Priority Mail Express packages, select Priority Mail packages, pickup services for Priority Mail Express and Amazon shipping, as well as retail services such as purchasing stamps. However, regular First Class mail delivery does not occur on Saturdays.

Are Packages Delivered on Sundays or Holidays?

USPS abstains from providing any mail delivery or pickup services on Sundays or major federal holidays, encompassing occasions like Christmas, New Year’s Day, Memorial Day, Independence Day, Labor Day, Thanksgiving Day, among others.

While UPS and FedEx may offer extremely limited delivery services on certain holidays, primarily for medical or emergency packages, standard shipping services are generally unavailable on Sundays or holidays across USPS, UPS, FedEx, and other carriers. It’s imperative to factor in holidays when calculating transit days.


How Long Does USPS Delivery Take?

The delivery duration for USPS mail and packages can exhibit significant variability. The time it takes for your mail to reach its destination hinges on various factors:

  • Type of mail or package dispatched
  • Distance to the destination
  • Seasonal fluctuations and mail volumes
  • Occurrence of weekends or holidays during transit

Here’s a breakdown of the typical USPS delivery times to anticipate:

  • First Class Mail: 1-3 business days for nearby addresses; up to 5 days for more distant delivery
  • Priority Mail: 1-3 business days
  • Priority Mail Express: Overnight to 2-day delivery
  • Retail Ground: 2-8 business days

The distance to the destination emerges as the primary variable. Utilize USPS’s official delivery time calculators to estimate the expected duration for your specific mail or package.

How to Count Business Days for USPS Delivery

Accurately determining the arrival day of your mail necessitates proper calculation of business days. Here are some pointers:

  • Consider weekdays only (Monday-Friday), except when dispatching Priority Mail on Saturday
  • Exclude Sundays and holidays from the count
  • For Saturday Priority Mail, treat each Saturday as a half business day
  • Account for an additional day if a holiday occurs during transit
  • Count only the days when USPS operates, excluding non-business days

Leverage USPS’s Postal Explorer tool for automated delivery day calculations. Simply input the shipping date and destination ZIP code to obtain the projected delivery date.

How Do Other Carriers Treat Business Days?

UPS and FedEx recognize every day except Sundays and major holidays as business days:

  • UPS – Monday through Saturday
  • FedEx – Monday through Saturday, with some evening deliveries

For shipments via UPS and FedEx, include all weekdays and Saturdays in your calculation, while disregarding Sundays and holidays.

Always refer to the specific carrier’s website to ascertain precise transit days for your package and address. Transit days may fluctuate regularly based on various factors.

Here are key strategies to ensure timely receipt of your mail and packages:
