Important Weeks and Fortnights: Dates and Observances
Exam notes on important weeks and fortnights: National Safety Week, Van Mahotsav, Wildlife Week, World Space Week, Vigilance Week and the pakhwadas.
By GK24 Editorial Team· Published · 4 min read

Besides single days such as Republic Day or World Environment Day, governments and international bodies set aside longer stretches of the calendar for a theme. A week runs for seven days and a fortnight, called a pakhwada in official Hindi, runs for about fifteen. The longer span is chosen when the message needs campaigns, camps and school activities rather than a single ceremony, which is why nutrition, safety, wildlife and vigilance are all given weeks. Examinations ask for the exact dates, for the body that observes the week and for the day from which it begins, so those three things are what this chapter fixes.
How a week is fixed
Three patterns cover almost every observance. Some weeks sit on fixed dates, such as 1 to 7 September for National Nutrition Week. Some are anchored to an important day and run outward from it, as National Safety Week begins on National Safety Day and Fire Service Week begins on Fire Service Day. Some are floating, described only by their position in a month, as World Immunization Week is the last week of April and Van Mahotsav is the first week of July. When a question gives a date and asks for the week, work back to the anchor day, because that is usually the fact being tested.
The weeks and fortnights most often asked
| Observance | When | Observed by or for |
|---|---|---|
| National Safety Week | 4 to 10 March | Begins on National Safety Day; industrial and workplace safety, National Safety Council |
| Fire Service Week | 14 to 20 April | Begins on Fire Service Day, in memory of the firefighters killed in the Bombay dock explosion of 1944 |
| World Immunization Week | Last week of April | World Health Organization; vaccination across the life course |
| Van Mahotsav | First week of July | Tree planting festival in India, begun in 1950 on the initiative of K. M. Munshi |
| World Breastfeeding Week | 1 to 7 August | World Health Organization and UNICEF |
| National Nutrition Week | 1 to 7 September | Ministry of Women and Child Development |
| Hindi Pakhwada | From 14 September | A fortnight in central government offices beginning on Hindi Diwas |
| Wildlife Week | 2 to 8 October | Ministry of Environment, Forest and Climate Change |
| World Space Week | 4 to 10 October | Declared by the United Nations General Assembly |
| Vigilance Awareness Week | The week containing 31 October | Central Vigilance Commission; anti-corruption pledge |
| Qaumi Ekta Week | 19 to 25 November | National Integration Week; ends with Communal Harmony Flag Day |
| World Antimicrobial Resistance Awareness Week | 18 to 24 November | World Health Organization; misuse of antibiotics |
Weeks anchored to a day
National Safety Week opens on National Safety Day, 4 March, the foundation day of the National Safety Council, and factories across the country hold drills and pledge ceremonies through the week. Fire Service Week opens on 14 April, the day in 1944 when a ship loaded with cotton and explosives caught fire in the Bombay docks and the firefighters who went to it were killed in the blast; the week honours them and teaches fire prevention. Vigilance Awareness Week is arranged by the Central Vigilance Commission around 31 October, the birth anniversary of Sardar Vallabhbhai Patel, and begins with an integrity pledge in offices. Qaumi Ekta Week, or National Integration Week, runs from 19 to 25 November and closes with Communal Harmony Flag Day.
Weeks for health and for nature
World Breastfeeding Week, from 1 to 7 August, is coordinated by the World Health Organization and UNICEF and presses the case for feeding an infant only mother's milk for the first six months. National Nutrition Week, from 1 to 7 September, carries the same argument into Indian anganwadis and schools, and the whole of September is separately observed as Poshan Maah, a nutrition month. World Immunization Week falls in the last week of April, and World Antimicrobial Resistance Awareness Week, from 18 to 24 November, warns against taking antibiotics without need or stopping a course halfway. On the side of nature, Van Mahotsav in the first week of July is the national tree planting festival, and Wildlife Week, from 2 to 8 October, is observed in national parks, sanctuaries and zoos.
Fortnights
A fortnight gives twice the room of a week and is used where an activity must actually be carried out rather than merely remembered. Swachhata Pakhwada is the cleanliness fortnight that each ministry of the central government takes up in turn through the year, so that every ministry gets its own two weeks of drives, inspections and repairs. Hindi Pakhwada begins on Hindi Diwas, 14 September, and central government offices spend the following days on competitions, workshops and reviews of official language work. Several states and departments also run a health fortnight, a plantation fortnight or a consumer awareness fortnight on the same pattern.
Revision advice
Learn the fixed-date weeks first, because they are asked most: 4 to 10 March, 1 to 7 August, 1 to 7 September, 2 to 8 October, 4 to 10 October and 19 to 25 November. Then attach each floating week to its anchor day. Do not mix up the two October weeks, since Wildlife Week begins on 2 October and World Space Week on 4 October, and note that 4 October is chosen because the first artificial satellite, Sputnik, was launched on that date in 1957, while the week ends on 10 October, the date of the Outer Space Treaty of 1967.
Exam Point of View
Almost every question is a date question, either the week to its dates or a date to its week, so the fixed-date list must be learned exactly. Two pairs cause most of the errors. The first is the October pair, Wildlife Week from 2 October and World Space Week from 4 October. The second is the nutrition pair, World Breastfeeding Week from 1 August and National Nutrition Week from 1 September, which share the first to the seventh and differ only in the month. A second line of questioning asks for the anchor day: 4 March for safety, 14 April for fire service, 31 October for vigilance and 14 September for Hindi Pakhwada. A third asks which body observes the week. Leave out the theme of the current year for any of these weeks, since the theme changes annually and is current affairs, not static general knowledge.

Practice MCQs on this topic
National Nutrition Week in India is observed every year from:
- A.1 to 7 August
- B.1 to 7 September
- C.2 to 8 October
- D.19 to 25 November
Show answer
Correct answer: B. 1 to 7 September
Explanation
The correct answer is B, 1 to 7 September. National Nutrition Week is observed by the Ministry of Women and Child Development through anganwadis, schools and health centres to spread the message of balanced diet, and the whole of September is separately kept as a nutrition month. Option A is wrong because 1 to 7 August is World Breastfeeding Week, coordinated by the World Health Organization and UNICEF; the two are close in theme and in shape, which is why they are placed together as options. Option C is wrong because 2 to 8 October is Wildlife Week in India. Option D is wrong because 19 to 25 November is Qaumi Ekta Week, the national integration week. Notice how many of these weeks run from the first to the seventh of a month, and separate them by month rather than by date.
World Breastfeeding Week is observed every year from:
- A.1 to 7 August
- B.4 to 10 March
- C.14 to 20 April
- D.18 to 24 November
Show answer
Correct answer: A. 1 to 7 August
Explanation
The correct answer is A, 1 to 7 August. The week is coordinated worldwide by the World Health Organization and UNICEF and argues for feeding a baby only mother's milk for the first six months, and for beginning that feeding within an hour of birth. Option B is wrong because 4 to 10 March is National Safety Week in India, which opens on National Safety Day and deals with workplace and industrial safety. Option C is wrong because 14 to 20 April is Fire Service Week, beginning on the anniversary of the Bombay dock explosion of 1944. Option D is wrong because 18 to 24 November is the World Antimicrobial Resistance Awareness Week, a health observance of a different kind, about the misuse of antibiotics. Both August weeks and September weeks concern nutrition, so anchor them by their month.
Wildlife Week in India is observed from:
- A.1 to 7 July
- B.2 to 8 October
- C.4 to 10 October
- D.22 to 28 April
Show answer
Correct answer: B. 2 to 8 October
Explanation
The correct answer is B, 2 to 8 October. Wildlife Week is observed in national parks, sanctuaries, zoos and schools across India with exhibitions, walks and competitions, and it is coordinated by the Ministry of Environment, Forest and Climate Change. Option A is wrong because the first week of July is Van Mahotsav, the tree planting festival begun in 1950. Option C is wrong and is the closest trap in the list, since 4 to 10 October is World Space Week, declared by the United Nations; both fall in the same October fortnight, so learn the starting dates, 2 October for wildlife and 4 October for space. Option D is wrong because the last week of April is World Immunization Week, which changes its dates slightly each year with the calendar.
Van Mahotsav, the national tree planting festival of India, is observed in:
- A.The first week of July
- B.The first week of June
- C.The last week of August
- D.The second week of September
Show answer
Correct answer: A. The first week of July
Explanation
The correct answer is A, the first week of July. Van Mahotsav was begun in 1950 on the initiative of K. M. Munshi, then the union minister for agriculture and food, and July was chosen because the monsoon has set in over most of the country by then and a sapling planted in wet ground has the best chance of surviving. Option B is wrong because the first week of June holds World Environment Day on 5 June, a single day and not a planting festival. Option C is wrong because the last week of August has no national plantation observance of this kind. Option D is wrong because the second week of September falls in the nutrition month and carries Hindi Diwas on 14 September. Tie the festival to the rain: monsoon first, planting second.
World Space Week, declared by the United Nations, is observed from:
- A.2 to 8 October
- B.4 to 10 October
- C.12 to 18 August
- D.1 to 7 November
Show answer
Correct answer: B. 4 to 10 October
Explanation
The correct answer is B, 4 to 10 October. The two dates were chosen for two events: on 4 October 1957 the first artificial satellite, Sputnik, was placed in orbit, and on 10 October 1967 the Outer Space Treaty came into force. Option A is wrong because 2 to 8 October is Wildlife Week in India, and mixing the two October weeks is the commonest error here. Option C is wrong because August holds no space week; National Space Day in India marks a lunar landing and is a separate single day. Option D is wrong because the first week of November has no such observance either. The easy hold is the anniversary of Sputnik: space week opens on the day the space age began.
Vigilance Awareness Week is observed by the Central Vigilance Commission around the birth anniversary of:
- A.Mahatma Gandhi
- B.Sardar Vallabhbhai Patel
- C.Jawaharlal Nehru
- D.Dr B. R. Ambedkar
Show answer
Correct answer: B. Sardar Vallabhbhai Patel
Explanation
The correct answer is B, Sardar Vallabhbhai Patel, who was born on 31 October 1875. The Central Vigilance Commission arranges the week around that date, and it opens with an integrity pledge taken in government offices and public sector undertakings; the same day is also observed as Rashtriya Ekta Diwas, the national unity day. Option A is wrong because the birth anniversary of Mahatma Gandhi, 2 October, is Gandhi Jayanti and the International Day of Non-Violence. Option C is wrong because the birth anniversary of Jawaharlal Nehru, 14 November, is Children's Day. Option D is wrong because the birth anniversary of Dr B. R. Ambedkar, 14 April, is Ambedkar Jayanti, which is also the day Fire Service Week begins. A useful cue is that the vigilance week is the only one of these tied to a birth anniversary that is itself a national observance, Rashtriya Ekta Diwas, so the two facts reinforce each other.
Qaumi Ekta Week, the National Integration Week, is observed from:
- A.19 to 25 November
- B.1 to 7 December
- C.26 January to 1 February
- D.14 to 20 August
Show answer
Correct answer: A. 19 to 25 November
Explanation
The correct answer is A, 19 to 25 November. The week is observed to strengthen national integration and communal harmony, with each day given a theme such as minorities welfare, linguistic harmony and women's day, and it closes on 25 November with Communal Harmony Flag Day. Option B is wrong because the first week of December carries Armed Forces Flag Day on 7 December, a separate observance for the welfare of ex-servicemen. Option C is wrong because 26 January is Republic Day, a single national day that begins no week of this kind. Option D is wrong because 15 August is Independence Day, again a single day. A flag day at the end of a week is a good clue to remember the November observance by.
National Safety Week in India begins on National Safety Day, which falls on:
- A.4 March
- B.8 March
- C.23 March
- D.1 May
Show answer
Correct answer: A. 4 March
Explanation
The correct answer is A, 4 March, the foundation day of the National Safety Council of India. The week that follows, from 4 to 10 March, is used in factories, mines, ports and construction sites for safety pledges, drills, inspections and competitions, with a different theme each year. Option B is wrong because 8 March is International Women's Day. Option C is wrong because 23 March is Shaheed Diwas, the day Bhagat Singh, Sukhdev and Rajguru were hanged in 1931. Option D is wrong because 1 May is International Workers' Day, also called May Day and Labour Day, which is about the rights of workers rather than their physical safety at work, and is therefore the option most likely to mislead. Remember the chain in order: 4 March National Safety Day, then the week to 10 March, with a fresh theme announced by the National Safety Council every year.
Fire Service Week in India begins on 14 April, in memory of firefighters killed in:
- A.The Bombay dock explosion of 1944
- B.The Bhopal gas tragedy of 1984
- C.The Chennai floods of 2015
- D.The Jallianwala Bagh massacre of 1919
Show answer
Correct answer: A. The Bombay dock explosion of 1944
Explanation
The correct answer is A, the Bombay dock explosion of 1944. A ship carrying cotton bales and explosives caught fire in the Bombay docks on 14 April 1944; the firefighters who went aboard to douse the blaze were killed when the cargo detonated, and Fire Service Day and the week that follows commemorate them. Option B is wrong because the Bhopal gas tragedy of December 1984 was a leak of methyl isocyanate and is remembered on its own anniversary. Option C is wrong because the Chennai floods of 2015 were a natural disaster with no connection to this observance. Option D is wrong because the Jallianwala Bagh massacre took place on 13 April 1919 in Amritsar; its date falls a day earlier, which makes it a deliberate trap in this question.
In official Indian usage, a pakhwada is a period of:
- A.Three days
- B.Seven days
- C.About fifteen days
- D.One month
Show answer
Correct answer: C. About fifteen days
Explanation
The correct answer is C, about fifteen days. A pakhwada is a fortnight, half of a lunar month, and government departments use it when a theme needs actual work rather than a ceremony; Swachhata Pakhwada, the cleanliness fortnight taken up by each ministry in turn, and Hindi Pakhwada, which begins on Hindi Diwas, are the standard examples. Option A is wrong because three days has no such name in official usage. Option B is wrong because seven days is a saptah, a week, the unit used for National Nutrition Week and Wildlife Week. Option D is wrong because a month long observance is called a maah, as in Poshan Maah in September. Learn the three words together: saptah for a week, pakhwada for a fortnight, maah for a month.
Hindi Pakhwada in central government offices begins on Hindi Diwas, which falls on:
- A.14 September
- B.14 November
- C.10 January
- D.21 February
Show answer
Correct answer: A. 14 September
Explanation
The correct answer is A, 14 September. On that day in 1949 the Constituent Assembly adopted Hindi in the Devanagari script as the official language of the union, and the anniversary is kept as Hindi Diwas, after which offices run a fortnight of competitions and reviews of official language work. Option B is wrong because 14 November is Children's Day. Option C is wrong because 10 January is World Hindi Day, which marks the first World Hindi Conference held in 1975 and is a different observance with a similar name, the very confusion this question is built on. Option D is wrong because 21 February is International Mother Language Day, declared by UNESCO. Keep the pair straight: 14 September at home, 10 January for the world.
World Immunization Week is observed in the last week of which month?
- A.February
- B.April
- C.July
- D.October
Show answer
Correct answer: B. April
Explanation
The correct answer is B, April. The World Health Organization keeps the last week of April for this campaign, which presses the case for vaccination at every age and reminds governments of the children still missed by routine immunisation. Because it is tied to the position of the week rather than to fixed dates, its exact days shift a little each year. Option A is wrong because February carries World Cancer Day on 4 February and National Science Day on 28 February, both single days. Option C is wrong because the first week of July belongs to Van Mahotsav in India. Option D is wrong because October already holds Wildlife Week from 2 to 8 October and World Space Week from 4 to 10 October. Floating weeks like this one are best learned by their month.
Frequently Asked Questions
What is the difference between a saptah, a pakhwada and a maah?
A saptah is a week of seven days, as in National Nutrition Week. A pakhwada is a fortnight of about fifteen days, as in Swachhata Pakhwada and Hindi Pakhwada. A maah is a month long observance, as in Poshan Maah, which fills the whole of September.
Why does World Space Week run from 4 to 10 October?
Both dates carry an event. On 4 October 1957 Sputnik, the first artificial satellite, was placed in orbit, and on 10 October 1967 the Outer Space Treaty came into force, so the week is framed between the start of the space age and the law that governs it.
Why does Van Mahotsav fall in July?
By early July the monsoon has reached most of India, and a sapling planted in wet soil has the best chance of taking root. The festival was begun in 1950 on the initiative of K. M. Munshi, then the union minister for agriculture and food.
Which weeks in India are anchored to a person's birth anniversary?
Vigilance Awareness Week is arranged around 31 October, the birth anniversary of Sardar Vallabhbhai Patel, which is also Rashtriya Ekta Diwas. Qaumi Ekta Week begins on 19 November, the birth anniversary of Indira Gandhi, and closes on 25 November.
Should the theme of a week be memorised?
No. Themes such as the annual slogan of National Safety Week or World Breastfeeding Week are announced afresh each year and belong to current affairs. For static general knowledge, learn the dates, the anchor day and the organisation that observes the week.
