## What is 2024 ColorCal by FourCatsApp?

ColorCal 2024

Color coded day-off calendar for Sunday/Rotating day off schedules.

IMPORTANT:
This calendar covers a very commonly used Color/Alpha scheme.  
If your Color/Alpha scheme does not match the App, please be
patient, I am working on an App with generic colors.

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

This calendar spans October 2023 (USPS 2024 Q1 ) thru January 2025
(USPS 2025 Q1 end)

What's new:
Removed the note and scratch pad feature.

NOTE: The SDO scheme depicted in this calendar, matches commonly
available printed calendars. FYI: There are too many color schemes to
possibly address them all. 
A generic SDO calendar is coming.

For security, there is no online calendar integration. It simply
displays your scheduled day off, holidays and paydays.
There's no SPAM, Ads, pop-ups, nag screens, push notifications,
in-app purchases or collection of personal data. The App does not
collect, save or ask for ANY information. It works without
connectivity.

WARNING: ONLY get the app from the Apple APP
store.  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
hold me harmless in the event of errors or omissions
