Can t change year on kindle fire 5?

I have changed the time many times but the date is stuck on March 26 2010. I am trying to log on to my wifi but it keeps saying my clock is behind no matter what time zone I pit it at. How do I change the date? I can t go to the calender because I m not able to log into my wifi because of this.

See if these manual settings are available on your Fire:

Else, try connect it to your computer via USB and then turn on the Kindle Fire. Maybe it can update its date from that connection.

You can also try updating its firmware via the USB connection, if it is not running the latest:
