About Indian Standard Time
Indian Standard Time is calculated with respect to 82.5°E longitude, which passes near Mirzapur, Uttar Pradesh. That meridian is the reference for the national offset of five and a half hours ahead of UTC.
Despite India’s large east–west span, one civil time is used across states and union territories so railways, broadcasting, and government services stay aligned.
IST vs GMT: GMT (often used to mean the time at the prime meridian) is not adjusted for summer in the same way as some regions; India stays fixed at UTC+5:30. When people say “GMT+5:30” they usually mean the same offset as IST.
Time & Vedic astrology
For a Kundli (birth chart), exact birth time in a known timezone—often recorded as IST in India—fixes the ascendant, house cusps, and dasha starting points. Even a few minutes can shift the chart in some cases, so use the precise time on your birth record when you use our tools.

What is the full official timezone name for IST?
In the IANA timezone database, IST is identified as Asia/Kolkata. The full name is India Standard Time (Asia/Kolkata).
Why does all of India use one time zone?
India uses a single offset (UTC+5:30) for the whole country for administrative and practical unity, even though the country spans a wide east–west distance. The offset is based on a standard meridian near 82.5°E (Mirzapur, Uttar Pradesh).
