Standard time year-round
Shanghai runs on China Standard Time (CST, UTC+8) year-round — same offset as the entire Chinese mainland. No DST. Business hours 9 AM - 6 PM in coastal Shanghai, often "996" (9 AM - 9 PM, 6 days a week) in Chinese tech — though this has legally been challenged and is less overt than a decade ago. SSE (Shanghai Stock Exchange) trading runs 9:30 AM - 3 PM CST with a 1.5-h lunch break.
East Asia — China, Japan, Korea, Taiwan, Mongolia — sits mostly at UTC+8 (China's single-timezone policy across the whole country) or UTC+9 (Japan, Korea). None observe DST anymore (Japan ended its post-WW2 experiment in the 1950s), so offsets are fixed. The region's single-large-zone footprint makes cross-Asia coordination unusually easy compared to Europe or North America.
