Earlier today, both the Nexus 4 and the Nexus 10 started receiving small ~1MB OTAs to Android 4.2.1 with fixes to the missing month of December in the People app, among other things. The corresponding open source files are being pushed by Google to the Android Open Source Project (AOSP) as we speak, Android release engineer Jean-Baptiste Queru just announced in the Android Building group.
The build number is JOP40D and the tag is android-4.2.1_r1.

File this one under How did Google not have a test for this? Got a birthday or anniversary in December? Sorry - Android 4.2 doesn't know what December is. Well, rather the People/Contacts app that comes stock and is part of the Android Open Source Project (AOSP) doesn't. Wait... what?
We couldn't believe it either, but it's true. Google forgot to include December. As in, there are 11 months in a year.
