About Central Daylight Time (CDT)
Central Daylight Time (CDT, IANA: America/Chicago during DST window) is the summer-time variant of CST, set at UTC-5:00 — observed from the second Sunday in March to the first Sunday in November per the US Energy Policy Act of 2005. CDT shares the same UTC offset as Eastern Standard Time (EST), so during winter months Chicago/Dallas are one hour behind New York/Atlanta, but during summer months Chicago/Dallas are still one hour behind because both regions advance equally for DST. The 'spring forward / fall back' transition affects an estimated 311 million US residents annually per Census data. CDT is used in 16 US states partially or fully (Illinois, Texas, Wisconsin, Minnesota, Iowa, Missouri, Arkansas, Louisiana, Mississippi, Alabama, Tennessee, Kansas, Nebraska, Oklahoma, North Dakota, South Dakota) and parts of Canada (Manitoba, western Ontario, Saskatchewan partial — Saskatchewan stays on CST year-round, an exception). Affects MLB season game scheduling, CME / CBOT commodity trading hours, and US-Canada-Mexico USMCA cross-border supply-chain handoffs.
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.
