YELLOW and "B" Rotating Scheduled Day Off

View your schedule on your Android device.

Read full description for details

If you have a color-coded Sunday / Rotating days off, this calendar is for you!

This version displays the YELLOW and "B" rotating days off used by many USPS installations. Other colors can be found in the PLAY store. Click here.

ColorCal PLUS displays rotating days off AND allows you to save notes (annual leave, sick leave, overtime, harassment, appointments, etc).

This app is designed for YELLOW and "B" Scheduled Day Off as depicted in the predominantly available calendars. If your office uses a variation, check out the other calendars I have created. I have created each of the six possible schedules in separate apps and posted an image of December so you can choose the calendar that matches your day off. Download the day off you need and disregard the color scheme.

*Paydays are outlined in green with green numbers.

*Start of pay periods are outlined in blue

*Holidays and notable days are numbered with an alternate color

For Security, there is no online calendar integration, or for that matter, any online requirement. Your notes are saved on your device. This is to minimize possible data leakage.

If you found the app helpful, SPREAD THE WORD!! (tell your co-workers and family) so I can keep making it.

Permissions for the app are:

*"write to memory" - so your notes can be saved.

*"access network state" - required by the software package. (I am not sure why it is needed the app works without connectivity)

If you want a calendar with fewer required permissions get ColorCal 2017. It does not need write permission because it does not save notes.


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.

WARNING: ONLY get apps from the Google PLAY store. Other sources may provide unsafe and/or hacked apps. For your safety, I only distribute through the Google PLAY store.

This app works on Android 4.1 and higher. It has been tested on KitKat 4.4.4 (MotoX, Nexus5, Galaxy S5), Jellybean 4.2.2 (Galaxy Tab2 7.0), Lollipop (Generic tablet and Marshmallow (Galaxy S7).


The calendar is believed to be correct. By using it you agree to hold me harmless in the event of errors or omissions
