What is a Year?

In the business world, a year is a 12-month period, four-quarter period, or 13-period stretch of time. It is not always 365 days long, though it is usually very close to that. In business, note that a fiscal year does not always go from January 1 to December 31; many companies have fiscal years beginning at other times.
 

How Does a Year Work?

Years are important because they create time frames for comparing information. For example, let's assume Company XYZ's fiscal year began on January 1 and that today is March 31. During this time, Company XYZ recorded the following:

By comparing the 2012 revenues with the 2011 revenues, we can calculate that Company XYZ was up 50% year over year.

Why Does a Year Matter?

Yearly information is useful in looking for trends or measuring performance against goals. Remember, though that comparing year-over-year information among companies with different fiscal-year start dates can distort an analysis: The time included may vary and seasonal factors may become skewed. It is also important to remember that the extra day in leap years may also distort comparisons.
