mcdevito75 here, The crown should be a 2 position crown, try this, pull out the crown as if to set the hands, rotate the hands, (adjust the time) around the dial until you have the right day, Now! push the crown in, Now! slip your finger nail just under the crown and lift the crown to it"s first notch or position, this should allow you to turn the crown and adjust the date, when at the date push the crown back in and your done.

My watch is experiencing the same problem. I just found out the following on Citizen's website:
"The factory has discovered a software anomaly in the calendar programming of the integrated circuit that affects some Skyhawk AT and other styles utilizing the U600 movement caliber produced in only 2007 for those watches receiving either the U.S. or Japanese time signals. Those customers receiving the German time signals or have pieces manufactured in other years are not affected. This anomaly results in the calendar displaying dates from 2016 even though the year is 2010."
It goes on to say that the watch needs to be sent in for a software update. Below is a link to the FAQ topic:

You can get instructions from the Citizen web site.

Go to "citizen.com" and on the upper right there is a menu. Click on "technical support" and then on "setting instructions"

Fill in the information required from the back of your watch and then click on "get setting instructions"

On mine you pull 1/2 way to set the date, to adjust the day of the week you have to go all the way around 24 hours while setting the time .

This will likely require you taking the back off, removing the battery, reinserting, and then shorting the battery and AC. You will also need to look up the manuel online from Citizen's website, or go to a jeweler to have them reset your perpetual calender.

Pull the stem out gently until it clicks once. Turn counterclockwise until the correct date appears. Pulling the stem out to the second/last click adjusts the time.
