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.

About Peru Time (PET)

Peru Time (PET, IANA: America/Lima) is the official civil time of the Republic of Peru, set at UTC-5:00 year-round. Peru abolished Daylight Saving Time long ago — a brief DST experiment in 1994 was discontinued — so PET is observed without seasonal change. PET serves approximately 34 million people across Peru's 24 departments + Constitutional Province of Callao. Major cities: Lima (10M metro — capital and the third-largest South American metro after São Paulo and Buenos Aires), Arequipa (1.1M), Trujillo (1M), Chiclayo (800K), Piura (500K), Iquitos (470K — gateway to Peruvian Amazon), Cusco (430K — gateway to Machu Picchu). PET is identical in offset to Eastern Standard Time (EST) US, Cuban Standard Time (CST-Cu), Colombia Time (COT), and Ecuador Time (ECT) — easing North-to-South-American cross-time-zone coordination during US winter months. Affects: Bolsa de Valores de Lima (BVL) trading hours, Machu Picchu Inca Trail permit time-stamps, Cuzco-Aguas Calientes PeruRail train scheduling, and Inca Sun Festival Inti Raymi June 24 celebrations.
