No one cares. You're resume doesn't need that level of specificity. Year started and year ended are sufficient. In fact, you can probably only put the year you completed your degree and not the year started and no one would notice or care. The only time people care about dates is when there are large recent unexplained gaps and there is nothing on a resume to indicate what constructive/productive activity (professional or educational) you were doing at the time.
