The easternmost longitude of India holds significant geographical and geopolitical importance. Located at 97°25²E, this point marks the farthest eastern boundary of the Indian mainland, situated in the state of Arunachal Pradesh. It is more than just a coordinate; it represents the beginning of the day for the country in terms of sunrise, as well as being a point of strategic relevance. Understanding this easternmost longitude helps in comprehending time zones, national boundaries, and the diversity of India’s vast geographical landscape.
Geographical Location and Coordinates
The easternmost longitude of India lies at 97 degrees 25 minutes east. This longitudinal point is located near the village of Kibithu in the Anjaw district of Arunachal Pradesh, a northeastern state that shares its borders with China, Myanmar, and Bhutan. The village is nestled in the rugged Himalayan terrain, surrounded by natural beauty and steeped in strategic significance.

Time Zone Implications
India operates under a single time zone known as Indian Standard Time (IST), which is UTC+530. This time is calculated based on the 82.5°E longitude, which passes near the city of Mirzapur in Uttar Pradesh. However, the easternmost point of India is about 15 degrees east of this reference, causing a significant time difference between sunrise and sunset in the northeastern and western parts of the country.
Why Time Difference Matters
The people in Arunachal Pradesh experience sunrise and sunset much earlier compared to western states like Gujarat. For example, the sun can rise as early as 430 AM and set around 400 PM in some parts of the Northeast. This mismatch has sparked ongoing discussions about having a separate time zone for northeastern states to better align with natural daylight hours and improve productivity.
Strategic and Geopolitical Importance
The easternmost point of India is not just a geographical fact but also of strategic importance. Arunachal Pradesh, where this point lies, is part of a sensitive border area shared with China. The region is subject to territorial claims by China, which considers it part of South Tibet. Consequently, India’s presence in this region, including the monitoring of its easternmost longitude, is vital for national security.
Military Relevance
- Presence of Indian Army and Indo-Tibetan Border Police (ITBP)
- Construction of roads and outposts for better border management
- Surveillance to monitor cross-border activity
Cultural and Ethnic Diversity
The region around India’s easternmost longitude is home to numerous indigenous tribes, each with their own unique languages, traditions, and cultural heritage. The Mishmi tribe, for instance, resides in the Anjaw district and contributes to the cultural richness of the region. These communities live in harmony with nature, practicing agriculture, weaving, and traditional crafts that have been passed down through generations.
Key Cultural Facts
- Traditional dances and music reflect deep spiritual beliefs
- Festivals like Reh and Tamladu are celebrated with great enthusiasm
- Many tribes follow animistic religions, often mixed with Buddhism or Christianity
Ecological Significance
The easternmost part of India is characterized by dense forests, river valleys, and high-altitude mountain ranges. It is part of the Eastern Himalayas, one of the world’s biodiversity hotspots. The region hosts a wide variety of flora and fauna, including rare species like the red panda, clouded leopard, and Mishmi takin. Because of its ecological importance, there are several protected areas and wildlife sanctuaries in the region.
Biodiversity Highlights
- Namdapha National Park, one of the largest protected areas in the country
- Over 500 species of birds, including hornbills and pheasants
- Rich vegetation ranging from tropical rainforests to alpine meadows
Connectivity and Infrastructure Challenges
Despite its importance, the region around India’s easternmost longitude faces major challenges in terms of infrastructure and accessibility. Steep terrain, landslides, and dense forests make transportation difficult. However, in recent years, efforts have been made to build better roads, bridges, and communication systems to improve connectivity and ensure the integration of remote border villages with the rest of the country.
Development Projects
- Border Roads Organization (BRO) initiatives to build highways and bridges
- Plans for better telecom coverage in remote areas
- Government schemes to boost tourism and local economy
Tourism Potential
Due to its natural beauty and cultural uniqueness, the easternmost longitude of India has potential as an offbeat tourist destination. Adventure seekers and nature enthusiasts often visit Arunachal Pradesh for trekking, bird watching, and cultural immersion. However, permits are required for domestic and foreign tourists due to the region’s sensitivity and proximity to international borders.
