Important Days in May and June: Dates and Facts — GK24 title card

Questions on important days are the cheapest marks in a general knowledge paper, because the answer is a single number and the number never changes. What does change is the theme announced each year, so an examiner rarely asks for a theme; the paper asks the date, or asks which day falls on a given date, or asks whose birth anniversary is marked by an observance. May and June carry two of the biggest days in the calendar, World Environment Day and the International Day of Yoga, and a set of Indian days, National Technology Day and Statistics Day among them, that examiners like because they carry a story.

Important days in May

May opens with International Labour Day on 1 May, which is also the foundation day of Maharashtra and Gujarat, the two states created on that date in 1960. World Press Freedom Day falls on 3 May and World Red Cross and Red Crescent Day on 8 May, the birth anniversary of Henry Dunant, the founder of the Red Cross movement and the first Nobel Peace Prize winner; 8 May is also World Thalassaemia Day. National Technology Day on 11 May marks the Pokhran nuclear tests of 1998 and the other technological achievements announced in India on the same day. International Nurses Day on 12 May is the birth anniversary of Florence Nightingale. World Telecommunication and Information Society Day on 17 May marks the founding of the International Telecommunication Union in 1865. Anti-Terrorism Day on 21 May is observed in India on the anniversary of the assassination of former Prime Minister Rajiv Gandhi. The month ends with the International Day for Biological Diversity on 22 May, Everest Day on 29 May, marking the first ascent by Edmund Hillary and Tenzing Norgay in 1953, the International Day of United Nations Peacekeepers on the same date, and World No Tobacco Day on 31 May.

Important days in June

June belongs to the environment. World Environment Day on 5 June was set up by the United Nations General Assembly after the Stockholm Conference on the Human Environment in 1972 and has been observed since 1973; it is the most frequently asked day of the month. World Oceans Day follows on 8 June and the World Day to Combat Desertification and Drought on 17 June. The International Day of Yoga on 21 June was proposed by India at the United Nations in 2014; the General Assembly adopted the resolution in December that year and the first observance was in 2015. The date was chosen because it is the summer solstice, the longest day of the year in the northern hemisphere. World Blood Donor Day on 14 June is the birth anniversary of Karl Landsteiner, who discovered the ABO blood groups. World Refugee Day falls on 20 June, the International Day Against Drug Abuse and Illicit Trafficking on 26 June, and National Statistics Day in India on 29 June, the birth anniversary of Prasanta Chandra Mahalanobis.

The days with a person behind them

Four of the observances in these two months are birth anniversaries, and that connection is asked as often as the date itself. 8 May is Henry Dunant's, 12 May is Florence Nightingale's, 14 June is Karl Landsteiner's and 29 June is P. C. Mahalanobis's. Two more are anniversaries of events: 11 May recalls the nuclear tests of 1998 and 21 May the assassination of Rajiv Gandhi in 1991. Note also the days that move with the week rather than the date, such as Mother's Day on the second Sunday of May and Father's Day on the third Sunday of June, because a question may ask for the rule and not for a number.

How to revise this chapter

Revise these two months as one list of about thirty rows, not as two separate months, because the paper mixes them. Say each date with its day aloud, then test yourself in the other direction by naming the date for a given day. Keep a separate short list of the Indian days, which are 1 May for Maharashtra and Gujarat, 11 May for technology, 21 May for anti-terrorism and 29 June for statistics; state examinations favour these over the international ones.

Exam Point of View

Three forms of this question appear in papers. The first gives a date and asks which day falls on it, the second gives the day and asks for the date, and the third asks whose birth anniversary an observance marks. Themes change every year and are therefore rarely asked, so spend no time on them. The traps in these two months are predictable. World Environment Day on 5 June is confused with World Oceans Day on 8 June and with the day against desertification on 17 June. The three Indian days sit close together, 11 May, 21 May and 29 June, and candidates swap them. Nurses Day on 12 May and Red Cross Day on 8 May are both linked to a famous name, so learn Florence Nightingale with the twelfth and Henry Dunant with the eighth. Finally, remember that Yoga Day was first observed in 2015, though the resolution was adopted in December 2014.

Frequently Asked Questions

Why is National Technology Day observed on 11 May?

It marks 11 May 1998, the day India carried out nuclear tests at Pokhran in Rajasthan. Two other achievements were announced in the country on the same day, the first test flight of the indigenous Hansa aircraft and a successful test of the Trishul missile. The day was declared soon afterwards to honour the work of Indian scientists and engineers.

When is the International Day of Yoga and why was 21 June chosen?

It falls on 21 June. India proposed the day at the United Nations in 2014, the General Assembly adopted the resolution in December of that year, and the first observance was held on 21 June 2015. The date is the summer solstice, the longest day of the year in the northern hemisphere, which gives it a place in many traditions.

Whose birth anniversary is International Nurses Day?

Florence Nightingale's. She was born on 12 May 1820 and is remembered for her work with wounded soldiers in the Crimean War and for founding modern nursing as a trained profession. Do not confuse this day with World Red Cross and Red Crescent Day on 8 May, which marks the birth anniversary of Henry Dunant.

Since when has World Environment Day been observed?

Since 1973. The United Nations General Assembly designated 5 June as World Environment Day after the Conference on the Human Environment held at Stockholm in 1972, the meeting that also led to the creation of the United Nations Environment Programme. A different country hosts the main event each year and a new theme is announced, so examiners ask about the date rather than the theme.

Why is 29 June observed as Statistics Day in India?

It is the birth anniversary of Prasanta Chandra Mahalanobis, the statistician who founded the Indian Statistical Institute, devised the Mahalanobis distance and shaped the plan model used in the Second Five Year Plan. The Government of India declared the day to recognise his contribution and to spread awareness of the use of statistics in planning.

Which day is observed on 21 May in India and why?

Anti-Terrorism Day, observed on the anniversary of the assassination of former Prime Minister Rajiv Gandhi on 21 May 1991. Offices and institutions take a pledge against violence on that date. Note that 22 May, the very next day, is the International Day for Biological Diversity, and the two are often placed together in the same set of options.
