USPS projected delivery dates

USPS's projected delivery dates are based on factors such as delivery address, shipping service and may exclude observed holidays and Sundays.
Day 1 or the "ship date" is calculated when the package is received at the USPS sorting facility + 1 day. The "ship date" does not include the processing time at the warehouse. However, we commit to delivering your order within the service level selected.

Service types:

Priority Mail Service projected delivery date = ship date + estimated delivery by zip code (1-3+ day delivery depending on where you live) excluding Sundays and observed holidays. Refer to the 2012 US Carrier Holiday Schedule for observed holidays.

Example:

2 day delivery zip code excluding Sundays & observed holidays (i.e. Thanksgiving).
