Chapter 4 of the Class 6 Social Science book introduces students to the concept of historical time and the sources used to study history. It explains how historians divide time into years, decades, centuries, and millennia to make sense of the past. The chapter also talks about different types of calendars, such as the Gregorian, Islamic, and Indian calendars, and how they help us track historical events. Students learn about various sources of history—like coins, inscriptions, books, tools, and oral traditions—that help us understand how people lived in earlier times. This chapter builds a strong foundation for learning about ancient civilizations and historical developments by showing how time and sources help us study the past.
Below are the solutions to all the textbook questions from Chapter 4 Timeline and Sources of History. These answers are designed to help Class 6 students understand how we measure historical time and the different sources that help us study history. The chapter also introduces important concepts like BCE and CE, timelines, and the role of primary and secondary sources in understanding the past.
Question 1. How do we measure historical time?
Answer: We measure historical time using calendars, timelines, and years. We also divide time into decades (10 years), centuries (100 years), and millennia (1000 years).
Question 2. How can various sources help us understand history?
Answer: Sources like old books, coins, tools, pictures, and buildings help us know what happened in the past and how people lived long ago.
Question 3. How did early humans live?
Answer: Early humans hunted animals, gathered fruits, lived in caves, used simple tools, moved from place to place, and made fire to cook food and stay warm.
Question 1. What is the earliest memory you can recollect? Do you remember how old you were at that time? Those memories together are a part of your past, maybe going five or six years back. How do you think understanding the past will help us understand the present world?
Answer: My earliest memory is when I went to school for the first time. I think I was around 4 years old. Understanding the past helps us know how things have changed over time. It tells us how people lived, what they discovered, and how the world developed. This helps us understand the present better and learn from past mistakes to make a better future.
Question 1. Such calculations are simple, but there is a catch. In the Gregorian calendar, there is no ‘year zero’. The year 1 CE follows immediately the year 1 BCE. Draw a simple timeline marking every year from 2 BCE to 2 CE; you will see that because of the absence of a year zero, only 3 years have passed between those two dates.
So to calculate the number of years between a BCE date and a CE date, you should add them but subtract 1 — in the above case, 2 + 2 – 1 = 3.
Practice a few examples with your classmates. For example, to return to the question about the Buddha, suppose we are now in the year 2024 CE, then the Buddha was born 560 + 2024 – 1 = 2,583 years ago.
Answer:
In the Gregorian calendar, there is no year zero.
That means the year 1 BCE is followed directly by 1 CE.
So, if you draw a timeline from 2 BCE to 2 CE, you’ll see that only 3 years have passed, not 4.
Here's how: 2 + 2 – 1 = 3 years.
To find the number of years between any BCE and CE dates, use this formula:
BCE year + CE year – 1 = Total years

Question 1. Create a timeline stretching from 1900 CE to the current year and place the dates of birth of your grandparents, parents, siblings and yourself. Also, mark the years that the 20th century CE begins with and ends with.
Answer:
Steps to Create the Timeline:
Draw a straight horizontal line.
Mark years starting from 1900 CE to 2025 CE at equal gaps.
Highlight these important points:
20th century began in 1901 CE
20th century ended in 2000 CE
Now, add your family's birth years. Example:
Example Timeline (you can change the years as per your family):
1901 CE – Start of 20th century
1945 CE – Grandfather born
1950 CE – Grandmother born
1975 CE – Father born
1978 CE – Mother born
2005 CE – Sibling born
2012 CE – You were born
2000 CE – End of 20th century
2025 CE – Current year

Question 1. Have you ever seen old coins, books, clothes, jewellery or utensils in and around your house? What type of information can we gain from such objects? Or from old houses or buildings?
Answer: Yes, I have seen old coins and utensils in my house. These objects tell us about how people lived in the past. Old coins can show us which kings ruled and what kind of money was used. Old clothes and jewellery show the fashion and culture of that time. Utensils tell us how food was cooked and eaten. Old houses and buildings help us understand the design, materials, and lifestyle of people many years ago.

Question 1. As a project, write the history of your family (or village if you live in one), using sources of history at your disposal. Ask your teacher to guide you.
Answer:
I live in a small village named Roshanpur in Uttar Pradesh. I collected information about my family and village from my parents, grandparents, and the Gram Panchayat records.
My great-grandfather was Amar Singh, a farmer, born in 1910 in this village.
My grandfather, Mahesh Singh, was also a farmer and was born in 1940.
We have an old photograph of Amar Singh and some family stories that helped me learn about our past.
Our village is believed to be settled around 500 A.D., nearly 1500 years ago, according to old village records.
I used oral history, old photos, and documents to prepare this family history.
Question 2. Can we compare historians to detectives? Give reasons for your answer.
Answer:
Yes, we can compare historians to detectives because both try to find out the truth using clues.
Detectives use clues to solve crimes.
Historians use old books, objects, inscriptions, and stories to find out what happened in the past.
Both ask questions, collect information, and carefully put pieces together to understand what really happened.
Question 3. A few exercises with dates:
(a) Place these dates chronologically on the timeline:
323 CE, 323 BCE, 100 CE, 100 BCE, 1900 BCE, 1090 CE, 2024 CE
Chronological Order:
1900 BCE
323 BCE
100 BCE
100 CE
323 CE
1090 CE
2024 CE
(b) If King Chandragupta was born in 320 CE, which century did he belong to? And how many years was that after the Buddha’s birth?
Answer:
King Chandragupta was born in the 4th century CE.
Buddha was born in 560 BCE.
So, 560 + 320 – 1 = 879 years.
Chandragupta was born 879 years after Buddha’s birth.
(c) Rani of Jhansi was born in 1828. Which century did she belong to? How many years was that before India’s Independence?
Answer:
Rani of Jhansi was born in the 19th century CE.
India became independent in 1947.
1947 – 1828 = 119 years
Rani of Jhansi was born 119 years before Independence.
(d) Turn ‘12,000 years ago’ into a date.
Answer:
Current year = 2024 CE
12,000 – 2024 + 1 = 9977 BCE
So, the date is around 9977 BCE.
