Google working on returning missing December to Android 4.2 users
Summary: A bug in the Android 4.2 'People' app has removed December as an option for users trying to input birthdays or other events in a contact's information.
Google is reportedly working on a fix for a strange bug in Android 'Jelly Bean' 4.2 that makes it impossible to set a contact's birthday for December.
The bug affects the Android 4.2 People app, in which the month of December simply does not exist for those entering a calendar 'event' in a contact's details. According to reports, Google is already working on a fix that will be found in a 4.2.1 update.

Android 4.2 is only found on a handful of devices at this point, including Google's Nexus 4 and Galaxy Nexus handsets, and the Nexus 7 tablet.
The version shares its Jelly Bean codename with Android 4.1, and offers only minor differences compared to that iteration, chiefly the addition of 'Gesture Typing' and a 360-degree panorama feature for the camera app.

No big deal
So much for FOSS quality
It's a fairly common mistake...
A mistake that should had being caught during regration testing
Things are released when the developer says is OK without any kind of independent testing. This is why the quality of Google code is always so poor.
I agree
However, claims that google don't test their code? Nah, don't believe you there. Clearly not enough testing or this would have been caught and this goes deeper than a single app developer chucking a half finished app into the store.

What do you want?
what do I want for free?
eliminate Mondays
December is lost in holidays anyway :)
All working fine
The calendar entries work fine for December 2012 and the Rotation works like how it's intended to be.
Quite Specific Problem
It's strange though, looking at the moire fringe like pattern between November and January, if I were a conspiracy theorist, I'd say the image has been tampered with! Fortunately I'm not, but I guess the photographer should have cleaned the grease off the screen before taking the picture.
tiny4579 from xda fixed this yesterday
Hey mmuzzy, I don't know if you saw this commit but from the looks of it, it broke the events showing december:
https://github.com/android/platform_...51aea8b6bad6c7
I think if you change line 1370 based on what I'm reading from
setMaxValue(displayedValues.length - 1);
to
setMaxValue(displayedValues.length);
December should show once again under events.
screenshot?
it's showing 12 months missing - Feb '12 to Jan '13

If it was iOS....
Yep, and if it was IOS,
It's Apple, this is a feature, not a bug!"
Fix the sluggishness of 4.2
I also noticed general framerate drops sporadically in every places.
Seems like Google undid some of the Project Butter stuff in 4.2
Here is the workaround
