Accountant Day is observed in Russia every November 21, celebrating the vital role of accountants in the economy. This date was chosen to commemorate the signing of the Federal Law on Accounting by President Boris Yeltsin in 1996, which regulates accounting activities in the country. On this day, accountants receive congratulations and gifts from colleagues and superiors, and they often participate in various professional events. Accounting, which includes fields such as financial accounting and tax accounting, has a rich history dating back to ancient civilizations, with modern practices evolving from the double-entry bookkeeping system developed in the 15th century. In addition to Accountant Day, Russian accountants also informally celebrate Senior Accountant Day on April 21 and International Accounting Day on November 10. With over 3.5 million accountants in Russia, this holiday serves as an opportunity to express gratitude for their contributions to businesses and the economy.
