Which of the following describes a one-year period relevant to financial management?

A fiscal year is a one-year period relevant to financial management that is used for accounting purposes. It is distinct from the calendar year, which runs from January 1 to December 31. Organizations may choose their fiscal year to coincide with their business cycles, which can provide a more accurate representation of financial performance. The fiscal year could start on any month, such as July to June, or October to September, depending on what best suits the organization's operational and financial planning needs.

In contrast to the fiscal year, the accounting period refers more broadly to any time frame used in accounting for the preparation of financial statements, and while it can be a year, it might also encompass shorter or different time frames. The calendar year is specific to the Gregorian calendar and not necessarily aligned with an organization's financial management needs, which is why the fiscal year is often preferred. Lastly, a financial quarter refers to a three-month segment of the fiscal year and is important for tracking short-term financial performance but does not encapsulate the entire year required for comprehensive financial management.
