সিন্ধু সভ্যতার কালসীমা।*** It is a difficult problem to determine the antiquity of the Harappa civilization. Mohenjodaro is still Waterlogged under. Apart from the introduction of new information and judicial system, the time of this civilization is always changed. After the discovery of Harappa civilization, it is possible to delay its time limit as far as possible. Sir John Marshall set the deadline between BC 3250 and 2750 BC. After that, the information obtained in various places in the Indus Valley and Mesopotamia, Under the Harappan civilization, it was tried to reduce the time of civilization through pottery color analyzes and radio karbon-14 tests. In the modern age, Dendro Chronology has its tendency to delay its timeframe.

Lowest period :*** Two stages of Harappa civilization's deadline. The lack of proper information has led to difficulties in determining the timing of Indus Civilization. However, scholars have tried to determine the duration of this civilization by analyzing the findings resulting from excavation. It is believed that the civilization was developed during the period between the Neolithic Age and the Iron Age. Iron is said to be here as a sign. Harappa civilization did not match any of the iron signs. There was close contact with the Indus Valley along the west. There was an introduction of iron in the middle of the second millennium BC. Estimates of scholars AD: Before the 1500s, the Iron Age began. The Aryan attacks in India were made before 1500 BC and Rigveda was compiled in 1400 BC. This time is considered to be the lowest period of Harappa civilization.

Senior period:*** It is very difficult to diagnose a high level of calcification. The early historians originally tried to take back the origin of the Harappa civilization, depending on Harappan civilization and the similarity of the Mesopotamian civilization. Similar seal of Indus Civilization found in Mesopotamia, Elam, Babylon Armada region. By determining their similar analogy, Stuart Pigt (1950) and Huilar (1946 and 1960 AD) determined Harappan deadline between 2500 BC and 1500 AD. According to Sir John Marshall, the duration of this civilization is from 3250 to 2750 BC. C. J. Gadd set the deadline for examining 12 seals 2500 to 1500 BC. Dr. Frankfurt Tale examined the two seals found in Assmare and determined their deadline for 2800 AD. Dr. Fabri examined a Sumerian Babylonian inscription found in the Indus Valley and said that the period from 2800 to 2300 BC. It may be said that the 2800 BC is Harappar's maximum deadline. So if adding 500 years to 2800, then 3300 BC, As a result, this is the birth of civilization.

*** Currently Radio Carbon-14 is the best time to calculate time. Through this test, the FairServices said that the period from AD 2000 to AD 1500 is the period. Reviewing the materials found in Mesopotamia, Buchanan commented that Harappa culture is the result of the phase 3000 BC. According to Agarwal, Harappar differentiated between city and border region. According to him, the time limit of Harappa city is approximate: 2300 to 2000 AD. The primary level of Harappa culture is in Kalibangan, Lothal, Rozdi, and the primary level is tested by Radio Carbon-14 BC: 2200 to 1700 A.D.
*** But it is true that determining the time of Harappa or Indus Civilization is all based on estimation. It is not possible to know the exact time limit if Sindhu Lepi is not the reading gate.
