The time of a place depends on the longitude that passes through it. Therefore, the standard time for each country is usually taken as the time of the central meridian that passes through it. India has a vast longitudinal extent. Since many meridians pass through it, it is important to adopt the local time of one central meridian of a country as the standard time for the country. Thus, we need a standard meridian for the country. In India 82 1/2 degreeE longitude determines the standard time. This is known as the Indian Standard Time. This longitude passes through Allahabad in Uttar Pradesh. Question Description Importance of standard meridian time and why do we need standard time ? for Class 9 2023 is part of Class 9 preparation.

This answer will extensively provide information about the Indian Standard Time (IST), the reasons for choosing a particular standard meridian, etc. Reasons behind selecting Standard Meridian of India • The time at the Central Meridian of a nation is considered as the Standard Meridian of the country to maintain uniformity of time to the best possible extent within the territorial limits of that nation. • There is a standard practice among all the countries in the world that the standard meridian of the countries has to be in the multiples of 7°30′ of longitude. • This is done so that the difference between Greenwich Meridian time and the standard time of a country can be expressed as multiples of an hour or half an hour. Hence 82°30′ E meridian passing through Mirzapur (Uttar Pradesh) has been selected as the ‘standard meridian’ of India. • The time difference between Greenwich Mean Time and the Indian Standard Time is 5 hours and 30 minutes. Need for more than 1 Standard Meridian in India • There is a wide difference in local time of places located at different ends of India due to a longitudinal extent of about 29° as India extends between 68°7’E and 97°25’E longitudes from west to east. • The sun rises about two hours earlier in the east (Arunachal Pradesh) than in the west (Gujarat). • For every one degree of longitude, the local time changes by four minutes, the difference between extreme two points of India would be about two hours.

The Arunachal Pradesh is the easternmost state and the Gujarat is the westernmost state. Naturally, they experience such variation in the local time because of the longitudinal distance of 30° longitudes. This longitudinal distance of 30° longitudes makes a difference of 2 hours between the Arunachal Pradesh and the Gujarat. Hence, when it is 6 a.m. in Arunachal Pradesh, the local time at Gujarat is supposed to be behind by 2 hours as compared to the Arunachal Pradesh, it is 4 a.m. Therefore, it is correct to say that when the sun has already risen in the Arunachal Pradesh, it is still night in the Gujarat. The latitudinal and longitudinal extent of India is almost the same in degrees (i.e. 30 degree) but in kilometres, the north-south distance is 3200 kilometres while that of east-west distance i.e. 3000 km. In order to bring uniformity in local time, the Standard Meridian of 82°30'E has been accepted. It passes through Mirzapur (U.P.). Hence, we can state that we need Standard Meridian for India to maintain a standard time. Hyderabad is situated between the Tropic of Cancer and the Equator. When the sun is in aphelion, then it shines to the north of Hyderabad and when the sun is in perihelion, it shines to the south of Hyderabad at midday but Delhi is in the north of Tropic of Cancer, so this phenomenon does not take place in Delhi. 1. India is not a pigmy because of her 3.2 million sq. kilometre area equal to the entire continent of Europe. It is not giant because of he...

We need a Standard Meridian for India because it ensures that all its locations have the same time. The Standard Meridian, with its longitude of 82°30’E and passage through Mirzapur in Uttar Pradesh, determines India’s standard time. Standard time is defined as synchronizing clocks within a specific geographical location to a single standard time rather than using solar time or a locally selected meridian (longitude) to produce a local mean time standard. Need for Standard Meridian for India India’s North-South extent is greater than its East-West extent. The following factors account for it: • While the difference in latitude remains constant throughout, the difference in longitude decreases as one gets closer to the poles. • At the equator, the distance between two longitudes is 111 km. It represents the difference between two latitudes. It is always 111 km but drops to 0 km at the poles. • As a result, the north-south extent and distance of India remain unchanged. • As the two longitudes get closer, the east-west extension bends in a U-shape, shortening the east-west distance. • The longitude lines are now closer together as a result, and the East-West distance is now shorter than the North-South distance. Standard Meridian of India Local time differs from one location to the next. Dibrugarh in Assam and Dwarka in Gujarat have different local times that differ by approximately one hour and forty-five minutes in India. As a result, the national standard time must be esta...

A standard meridian is a line of longitude used as a reference point for measuring the position of places on the earth. The world’s standard meridian is the Prime Meridian, which passes through Greenwich, England. India’s standard meridian is the 82nd meridian east of the Greenwich Meridian, which passes through the town of Mirzapur in Uttar Pradesh. This meridian is used as a reference line to measure the location of places in India. Why We Need a Standard Meridian The need for a standard meridian has been felt since the early days of cartography and navigation. It helps in accurately determining the geographical coordinates of places on the earth. A standard meridian also serves as a reference line for mapping and navigation. It is used to measure time zones, calculate distances, and to draw accurate maps of the world. Explaining the Need for India’s Standard Meridian India has its own standard meridian, which is the 82nd meridian east of the Greenwich Meridian. This meridian is used as a reference line for measuring the location of places in India. It is important for India to have its own standard meridian to accurately determine the geographical coordinates of places within its borders. This is especially important for mapping and navigation purposes, as it helps in calculating the distances between different places in India. It is also used to determine the time zones in various parts of India, which is important for keeping track of time. Having a standard meridian ...
