Dates on resume

Hi all,

I am editing my resume. I work in a nursing home and wanted to know from when do I put down that I began working here: from the month in which i was hired, from when I started orientation, or when I actually began working?

The day you officially starting working for them -- when you start actually working for them and getting paid for it -- usually the first day of orientation.

Usually, people just list the month and the year.
