2023 USPS Carrier ColorCal

ColorCal 2023

Postal Color and Alpha (A-F) Coded calendar for Postal Letter Carriers and Clerks using USPS Sunday/Rotating Scheduled Day Off (SDO) calendar

This calendar spans October 2022 (USPS 2023 Q1 ) thru January 2024 (USPS 2024 Q1)

What's new:

Added a scratch pad feature for making quick notes

Added Juneteenth federal holiday as a reminder

NOTE: The SDO scheme depicted in this calendar, matches commonly available printed calendars. (There are too many color schemes to possibly address them all)

For security, there is no online calendar integration. It simply displays your scheduled day off, holidays and paydays. NO complicated or intrusive settings.

There is no SPAM, Ads, pop-ups, nag screens, push notifications, in-app purchases or collection of personal data. It does not collect, save or ask for ANY information. The app works without connectivity.

WARNING: ONLY get the app from Google PLAY OR the Apple APP store. Other sources may provide unsafe and/or altered (hacked) apps whose safety cannot be verified.


Requires Android version 5.1 and up
