2026 ColorCal

Alpha / Color coded day-off calendar for Sunday/Rotating day off schedules used by many USPS letter carriers and clerks

This calendar spans October 2025 (USPS 2026 Q1) thru January 2027
(USPS 2027 Q1)


NOTE: The SDO scheme depicted in this calendar, matches many of the
available printed calendars. Unfortunately, there are too many color schemes to possibly address them all. If your Color/Alpha scheme does not match the app, it is still useable by matching your current SDO to the corresponding color.

There is no online calendar integration. It simply
displays your scheduled day off, holidays and paydays.

There is no SPAM, Ads, pop-ups, nag screens, push notifications,
in-app purchases or collection of data.

The App does not collect, save or ask for ANY information.

It works without connectivity.

NOTE: ONLY get this app from the official App
stores. Other sources may provide unsafe and/or altered (hacked) apps
whose safety cannot be verified.

The calendar is believed to be correct. By using it you agree to
