How to Convert Brasília Time to India Standard Time
Formula
To convert Brasília Time (BRT) to India Standard Time (IST): Convert BRT to IST
About Brasília Time (BRT)
Brasília Time (BRT, IANA: America/Sao_Paulo) is the official civil time of Brazil's most populous regions, set at UTC-3:00 — named after the federal capital city of Brasília. BRT serves approximately 175 million people across 23 of Brazil's 26 states + Federal District including the megacities São Paulo (12M), Rio de Janeiro (6.7M), Salvador (2.9M), Fortaleza (2.7M), Belo Horizonte (2.5M), Brasília (3.1M), Curitiba (1.9M). Brazil abolished Daylight Saving Time in 2019 by Presidential Decree 9772/2019 (citing minimal energy savings and disruption costs), so BRT is observed year-round without seasonal change since then. Acre State and a small portion of Amazonas use Acre Time (ACT = UTC-5:00); the remainder of Amazonas plus Mato Grosso/Mato Grosso do Sul/Rondônia use Amazon Time (AMT = UTC-4:00); the Fernando de Noronha archipelago uses UTC-2:00. BRT affects: B3 (São Paulo Stock Exchange) trading hours, Brazilian football Série A match scheduling, and Petrobras / Vale international corporate-call timing.
About India Standard Time (IST)
India Standard Time (IST, IANA: Asia/Kolkata) is the civil time of the Republic of India and Sri Lanka, set at UTC+5:30 — one of the world's most populous 30-minute-offset time zones. India does not observe Daylight Saving Time per the Government of India directive (a brief DST trial in 1942-1945 during WWII was discontinued; subsequent proposals from 2010-2017 were rejected by the Indian Government citing minimal energy savings + agricultural sector disruption). IST is defined as the local mean solar time at 82.5°E longitude (passing through Shankargarh fort in Uttar Pradesh, with the reference clock at the National Physical Laboratory in New Delhi per the Indian Institute of Astrophysics). The 30-minute offset is preserved because India's east-west extent (68°E to 97°E) spans ~28° of longitude — approximately 2 hours of solar time — and the central meridian is most representative for a single unified zone. IST serves approximately 1.4 billion people in India + 22 million in Sri Lanka (Sri Lanka observes SLST = UTC+5:30, identical to IST). Major cities: Mumbai (12.5M), Delhi (16.8M, NCR 29M), Bengaluru (8.4M), Hyderabad (10M), Chennai (7M), Kolkata (4.5M), Ahmedabad (5.5M), Pune (3.1M). Affects: BSE/NSE stock exchanges, IPL Indian Premier League cricket schedules.
