Singapore Time (SGT)
Singapore operates on Singapore Time (SGT). This time zone does not observe Daylight Saving Time.
Time Zone: Singapore Standard Time (SST) — Standard Offset: UTC+8 (SGT) — DST: Not observed
Country: Singapore
This city does not observe Daylight Saving Time. The UTC offset remains constant year-round, which simplifies international scheduling.
Singapore operates on SGT (UTC+8), the same offset as Hong Kong, Taipei, Perth, and mainland China — making it the most commercially significant time offset in Asia. Singapore does not observe DST, keeping the offset constant year-round. The city-state's position as a global financial hub means SGT is one of the most important time zones in international business, particularly for banking, shipping, and commodity trading.
The Singapore Exchange (SGX) trades from 9:00 AM to 5:00 PM SGT. Singapore's time zone provides crucial overlap with markets across Asia — identical hours with Hong Kong (HKEX), and just 1 hour behind Tokyo (TSE). When Singapore's market opens, India's markets (BSE/NSE) have been trading for 1.5 hours. This clustering has made Singapore a hub for Asian-focused hedge funds and trading operations that need to monitor multiple regional markets simultaneously.
Singapore's UTC+8 offset creates distinct scheduling windows. For London (8 hours behind), the overlap is early morning Singapore or late afternoon London — a 9 AM SGT call is 1 AM GMT, so realistic overlap starts around 3 PM SGT (7 AM GMT). For New York (13 hours behind), the gap is severe: 9 AM SGT is 8 PM the previous night in New York. Most Singapore-US coordination happens through asynchronous communication or extreme schedule flexibility on one side.
Singapore, Hong Kong, Shanghai, Taipei, and Perth all share the UTC+8 offset, creating a massive same-time-zone business corridor across Asia-Pacific. This makes intra-Asian coordination remarkably smooth — a conference call between Singapore, Hong Kong, and Shanghai requires zero time zone math. The only wrinkle is Japan and Korea at UTC+9, which is a manageable 1-hour difference. India at UTC+5:30 is 2.5 hours behind, making morning Singapore calls work for midday India.
