Reference excerpt

World Milk Day is an international day established by the Food and Agriculture Organization (FAO) of the United Nations to recognize the importance of milk as a global food. It has been observed on June 1 each year since 2001. The day is intended to provide an opportunity to bring attention to activities that are connected with the dairy sector.

History World Milk Day was first designated by the FAO in 2001. June 1 was chosen as the date because many countries were already celebrating a milk day during that time of year. The Day provides an opportunity to focus attention on milk and raise awareness of dairy’s part in healthy diets, responsible food production, and supporting livelihoods and communities. This is supported by FAO data showing that more than one billion people's livelihoods are supported by the dairy sector and that dairy is consumed by more than six billion people globally. The fact that many countries choose to do this on the same day lends additional importance to individual national celebrations and shows that milk is a global food.

World Milk Day celebrations World Milk Day 2016 In 2016, World Milk Day was celebrated in over 40 countries. Activities included marathons and family runs, milking demonstrations and farm visits, school-based activities, concerts, conferences and seminars, competitions and a range of events focusing on promoting the value of milk and illustrating the important role played by the dairy industry in the national economy.

Worked examples

Example 1 — a first encounter with World Milk Day

Start with the simplest possible case. Write down what World Milk 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 World Milk 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 World Milk 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 World Milk Day

In research: World Milk 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 World Milk 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: World Milk Day is common in secondary-school and first-year university syllabi. It links to neighbouring topics June observances, Milk, Observances about food and drink, so understanding it makes those chapters shorter.
In everyday life: Look for World Milk 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.
