A rolling year is a 12-month period that begins and ends on a specific date. Government agencies and enterprises occasionally employ rolling years.
Companies utilise rolling years to assess when an employee is eligible for health insurance and to compute benefits like family medical leave. Rolling years are calculated the same way for all employees in the business world, regardless of their position.
Because their start dates differ, a rolling year may not coincide with a fiscal or calendar year. Calendar years sometimes contain leap years, and approximately 65 percent of publicly traded corporations around the world have the same fiscal year.
