If you're referring to field IT0022-BEGDA, I'm not sure that is doable. Multi-languages work via the Translation option at the data element level (Display the Data Element, Select GoTo->Translation). Data element BEGDA is used throughout the system, not just in IT0022. So by changing the Data Element itself, you might start seeing 'Graduation Date' on other infotypes, too.
Personally, we solved this by creating an Additional, custom field in IT0022 for Graduation Year. We have the field in ESS as well, for employees to update.
