Reference excerpt

International Coffee Day is an occasion that is used to promote and celebrate coffee as a beverage, with events now occurring in places around the world. The first official date was 1 October 2015, as agreed by then International Coffee Organization and was launched in Milan. This day is also used to promote fair trade coffee and to raise awareness for the plight of the coffee growers. On this day, many businesses offer free or discounted cups of coffee. Some businesses share coupons and special deals with their loyal followers via social networking. Some greeting card companies sell International Coffee Day greeting cards as well as free e-cards. Many countries around the world celebrate their own national coffee days at various dates throughout the year. In March 2014, the Member States of the ICO (International Coffee Organization) agreed to organise International Coffee Day on 1 October to create a single day of celebration for coffee lovers around the world.

History At a meeting on 3–7 March 2014, a decision was taken by the International Coffee Organization to launch the first official International Coffee Day in Milan as part of Expo 2015. Various events have been held, called Coffee Day or National Coffee Day, with many of these on or around September 29. The exact origin of International Coffee Day is unknown. An event was first promoted in Japan in 1983 by the All Japan Coffee Association (全日本コーヒー協会). In the United States "National Coffee Day" was mentioned publicly as early as 2005. The name "International Coffee Day" was first used by the Southern Food and Beverage Museum, which called a press conference on 3 October 2009 to celebrate it and to announce the first New Orleans Coffee Festival. It was promoted in China by the International Coffee Organization, first celebrated in 1997, and made into an annual celebration in early April 2001. Taiwan first celebrated International Coffee Day in 2009. Nepal first celebrated National Coffee Day on 17 November 2005. On 10 March, 2026, the UN General Assembly adopted 1 October as International Coffee Day.

Worked examples

Example 1 — a first encounter with International Coffee Day

Start with the simplest possible case. Write down what International Coffee Day claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to International Coffee Day before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about International Coffee Day ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of International Coffee Day

In research: International Coffee Day appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses International Coffee Day in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: International Coffee Day is common in secondary-school and first-year university syllabi. It links to neighbouring topics April observances, Coffee culture, International observances, so understanding it makes those chapters shorter.
In everyday life: Look for International Coffee Day outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
