A "food day" refers to a specific calendar day designated to celebrate, commemorate, or acknowledge a particular type of food or drink. While widely known in some regions, these culinary observances are a global phenomenon, with many countries establishing such days to highlight their diverse gastronomic heritage and popular consumables. The article lists a wide array of nations, from African countries to Japan, Canada, and the United Kingdom, indicating a widespread practice of dedicating specific days to food.

The proliferation of food days is particularly notable in the United States, where, as of 2014, there were over 365 days dedicated to specific foods or drinks, effectively assigning a unique culinary theme to almost every day of the year. This abundance often translates into promotional opportunities, with numerous reports highlighting "National Food Holidays" that offer free meals or treats to consumers, turning these designations into occasions for public engagement and commercial benefit.

The origins of these "national" or "international" food holidays are often less about official government proclamations and more about strategic marketing. Many are reportedly initiated by public relations firms, food industry groups, or even individuals seeking to promote specific products or raise awareness. This commercial underpinning explains the continuous growth in the number of these designated days, as companies and organizations find them an effective way to generate publicity and foster consumer interest in various food and drink items.

While the detailed list of specific food items for each country is not provided in the article, the presence of sections for nations like Germany, India, Sweden, and Brazil confirms the international appeal of these designated days. Whether celebrated with special dishes, promotional offers, or simply as a fun acknowledgment, food days serve as a cultural touchpoint, encouraging people to appreciate and explore the vast world of food and drink. They transform the mundane calendar into a perpetual feast, celebrating everything from specific snacks to broader categories like wine or cookies.
