Ever since the beginning of time, human history is full of events, discoveries and innovations. We mark events with the dates of their occurrence for the ease of remembering. The year 1600 tells us about the establishment of the East India Company, which helps recall the first steps of the British in India. We use dates to mark periods of history and identify events based on these eras. Our history textbooks are full of dates of events of historical importance.

All of us are familiar with dates mentioned in BCE in history books. Do you know what BCE abbreviates for? Before the Current Era, which means that the incident dates back to another era of the calendar. This brings us to our discussion of why past dates are important in history. Before we answer why dates are important, let us look at the various routine practices in which dates play a significant role.

Historians have used dating procedures to identify the eras to mark events and places. When identifying prehistoric places of settlements, knowing the era to which the place belongs becomes essential. Several places, such as Dholavira, the  Ashoka Pillar, are of historical and cultural significance. To understand their importance, they are categorised into the era they belong to.

A study of the era helps understand the historical context and relevance of a particular person, an artefact or an event. Dates help separate one period from another. It also tells us about the difference in cultural practices and traditions followed.

You would have also studied the various dynasties that ruled the nation. The calendar dates help devise a chronology to determine the order in which the foreigners came to rule. These dates help us recognise the various aspects of an era.

To remember the Battle of Panipat, you recall the era of King Babar, the founder of the Mughal dynasty. This tells us about the 1500s. We connect this event with the establishment of the Mughal dynasty. Hence, events can be interlinked when we know the date of their occurrence. Historians use this method to identify the eras to which events belong with detailed accuracy.

For instance, when we talk of the bombing of Hiroshima by America in 1945, the date immediately reminds us of the second world war. The Japan disaster was one of the repercussions of the second world war. Dates help study why a certain event happened and how that led to another incident. This tells us about the association between events.

Similarly, in Indian history, the Non-Cooperation movement was the first organised revolt against British rule under Mahatma Gandhi’s leadership. Due to the Jallianwala Bagh massacre in 1919, this act received nationwide support. These date links between events help us to study the events of history.

#2. Identify Important Events

Dates help identify events of historical significance. The date 2nd October or 15th August or 26th January need no introduction; they speak for the important events they signify. In other words, dates act as records of history. History books are all about important events and their dates. It becomes easy to remember events in this way through dates.

#3. Identifying Long-term Effects of an Event

When historians identify a specific place or event, they try to find the particular event’s period. Identifying the dates tells a lot about the event. It helps us understand the cultural differences, human geography, and practices followed in different places, in different periods. These data further help predict and analyse the long-term impact of such events.


Dates have been used for a long time by humans for keeping track of the passage of time. They help us identify events, relate them and study the causes.
