International Accounting Day, also known as International Accountant’s Day, is observed worldwide every November 10. This date was chosen to honor Luca Pacioli, recognized as the “Father of Accounting and Bookkeeping,” whose influential book published on this day in 1494 included a section on double-entry bookkeeping, a method still in use today. The holiday celebrates the importance of accounting and those who manage financial records, with many organizations and businesses acknowledging their accountants through congratulations and gifts. The origins of accounting can be traced back to ancient civilizations, with early bookkeeping practices evident in Mesopotamia and Egypt. Although the principles of accounting have evolved, they have largely remained consistent since the Middle Ages, encompassing various subfields such as financial accounting and auditing.
