In a glaring omission, the latest version of Android (v4.2) seem to have missed out on December month.
One Android (v4.2), one cant set any date in December as birth date of a contact and the the problem is that the option is missing from the front-end.
The issue was first reported to the Android development mailing list on November 14:
"Today I was inserting birthday of a friend in my contact list so that I can sync the birthdays in my calendar. I noticed that the December month is missing. When I pressed new event the calendar came but it was not having the option for the month December. I'm using Galaxy nexus running on 4.2 jelly bean which I installed yesterday on 14 November 2012.
Please help me with this as I use the calendar a lot"
If you add a contact via Gmail, the information syncs up just fine with your phone. Just that you cannot add/ edit contact details to include a date in December.
Meanwhile, Google has acknowledged the problem and is ecpected to fix the issues soon. Google, Android 4.2 users form a tiny fraction of the Android user base.
