Fiscal Year

12 month period not beginning on January 1, that is used to measure operations.

When entities measure their yearly performance, they usually look at the period beginning January 1st and ending December 31st. Often times schools will measure their year from September to August to conform to the school year. Because their year does not start on January 1st, we say they have a fiscal year.
