Understanding the concept of accounting periods is essential for accurate financial reporting, tax compliance, and decision-making. This article explores the definition, types, importance, and implications of accounting periods in financial management.


1. What is an Accounting Period?

An accounting period is a predetermined duration during which financial transactions are recorded, summarized, and reported. It ensures consistency and comparability in financial statements.

A. Definition and Purpose
