We generally tend to associate the past with dates where the focus is more on political events, dynasties, rulers and their achievements. We must understand that the past is also about social, economic and cultural developments that occurred at different points of time. When it all happened, what happened at that time (key events), how things developed or stayed the same (continuity and change) who contributed and who was affected and the sequence of events. The notion of time in the discussion of any given historical process or period does not always have to be dated in terms of a particular month or even a year. In the case of political events specific dates become important but in social and economic developments broader time periods assume significance. It would be incorrect to fix precise dates to processes that happen over a period of time because time also reflects changes in social and economic organization, and in the transformation of ideas and beliefs For example the Harappan civilization did not come to an end suddenly, but it happened over a period of time. Similarly people in India did not begin to play cricket or start drinking tea or women did not wear the sari one fine day. So also we cannot fix one single day on which the Mughal Empire was established or a particular date when the national movement started. All such developments occurred over a period of time. In History, we look at developments that occurred over a span of time over which particular chnrges became visible. The rebellion of 1857 did not occur on a precise date but the discontent that led to the revolt was already prevalent earlier before it culminated in the revolt of 1857.History is therefore more about developments/processes and changes/continuities that have occurred over a period of time.
