Example Mail Delivery Calculation
Imagine you are sending a package with the following details:
- Service: Priority Mail
- Origin ZIP: 10001
- Destination ZIP: 90001
- Ship Date: March 5
- Saturday Delivery: No

Understanding USPS Mail Services and Delivery Speed
Priority Mail Express
The fastest USPS option, typically delivering within 1–2 days.
Priority Mail
A popular choice for packages, usually delivered within 2–3 business days.
First-Class Mail
Ideal for letters and lightweight packages, generally arriving within 2–5 business days.
Media Mail

How ZIP Codes Affect Delivery Time
The calculator estimates distance using the starting digits of ZIP codes. Mail traveling across regions or states usually takes longer than local or regional shipments. Greater distance typically means more transit days.

One of the most important features of this calculator is its focus on business days.
- Sundays are always excluded

This helps provide a more realistic delivery estimate compared to simple calendar-day calculations.
