Data Base editing

Freelancer must know Apple os and be knowledgeable in apple development, I have a data base built already that I need minor editing. This is a very simple update task shouldn't take more then 15 minutes since the data base is built already and only needs to edit one thing. I need to change the year date on my data base it currently stops at 2016 I need it to go from 2017- Infinity thats all.
