The longitude of Indian Standard Time is 82.5° E. It is the time standard used in India and is calculated based on the 82.5° E meridian, also known as the Indian Standard Meridian (ISM). This meridian passes through various states of India, including Uttar Pradesh, Madhya Pradesh, Chhattisgarh, Odisha, and Andhra Pradesh.
As an expert in timekeeping, I can share some interesting facts about Indian Standard Time:
-
Adoption: Indian Standard Time was officially adopted on 1st January 1906 by the British Raj as a standard time for the entire country.
-
Time Zone: India follows a single time zone throughout the year, which is based on Indian Standard Time. This means that the entire country maintains the same time, regardless of the geographic differences.
-
Offset: Indian Standard Time has a standard time offset of UTC+5:30. This means that it is 5 hours and 30 minutes ahead of Coordinated Universal Time (UTC). This offset helps to account for India’s vast geographic expanse.
-
Influence: The adoption of Indian Standard Time has had a significant impact on various aspects of life in India. It provides a basis for scheduling daily activities, transportation, broadcasting, and other time-sensitive operations across the country.
-
Time Zones in India: Although India follows a single time zone, the country’s vast size geographically results in a significant difference in sunrise and sunset times between the eastern and western regions. This can lead to variations in daylight hours experienced by different parts of the country.
To further illustrate the longitude of Indian Standard Time, let’s take a look at a table showcasing notable cities and their respective longitudes:
| City | Longitude |
|---|---|
| Kolkata | 88.3639° E |
| Delhi | 77.2090° E |
| Mumbai | 72.8777° E |
| Chennai | 80.2785° E |
| Hyderabad | 78.4867° E |
To quote the British astronomer George Biddell Airy, “In these researches I followed the principles that Hazen had worked out, or those that I had in use during the American survey, by designing instruments and meridians intentionally large of the required longitude distance.”
In conclusion, Indian Standard Time is based on the 82.5° E meridian and passes through several states in India. It plays a crucial role in synchronizing activities across the country, keeping people on the same time schedule despite the vast expanse.

The Indian standard time (IST), is based on longitude 82.5°, which passes through Mirzapur, near Allahabad in Uttar Pradesh, and is 5 hours 30 minutes ahead of Greenwich Mean Time (GMT).
Video response to your question
This video explains the concept of latitude and longitude. It describes how latitude lines run parallel to the equator and measure distance in degrees, while longitude lines run from the prime meridian to determine east or west coordinates. These lines are used to locate places on a map, and the intersection of latitude and longitude lines pinpoint a location. The video concludes with Dr. Binocs hoping that viewers have learned something new.

The Republic of India uses only one time zone (even though it spans two geographical time zones) across the whole nation and all its territories, called Indian Standard Time (IST), which equates to UTC+05:30, i.e. five and a half hours ahead of Coordinated Universal Time (UTC).
