Tokyo observes Japan Standard Time (JST, UTC+9) year-round. Japan abolished Daylight Saving Time in 1951, after experimenting with it during the post-war US occupation (1948–1951), and has not reinstated it since. The fixed UTC+9 offset means that Tokyo's sunrise and sunset times shift significantly across seasons — the sun rises before 04:30 in late June and after 06:50 in late December — but the clock never moves. Japan Standard Time is shared by the entire country, which spans only about 30° of longitude, making a single national timezone practical.
Tokyo is the world's most populous metropolitan area and a global financial powerhouse. The Tokyo Stock Exchange (TSE) opens at 09:00 JST and closes at 15:30 JST with a lunch break from 11:30 to 12:30 — one of the few major exchanges still observing a midday break. Tokyo's fixed UTC+9 means the trading day never shifts relative to the rest of the world's schedules: TSE always closes at 06:30 UTC, just as European morning trading begins. The lack of DST simplifies scheduling with Tokyo; you never need to check "is Japan currently on DST?" — it is always UTC+9.
Tokyo is 9 hours ahead of London (GMT), 14 hours ahead of New York (EST), and 17 hours ahead of Los Angeles (PST). This puts Tokyo so far ahead of the Americas that a live daytime meeting covering both is virtually impossible during normal business hours for either side. It is 1 hour ahead of Beijing and Seoul, and exactly the same offset as South Korea (KST) in winter. The JST zone also covers South Korea's Jeju island in practice, though Korea officially uses KST (also UTC+9).
Dubai observes Gulf Standard Time (GST, UTC+4) year-round. The UAE has never observed Daylight Saving Time, making Dubai one of the most consistent timezone anchors in the world for scheduling purposes. GST is shared by the UAE and Oman. The fixed UTC+4 position places Dubai midway between Europe and Asia — it is 4 hours ahead of London (GMT), 9 hours ahead of New York (EST), and 4 hours behind Singapore (SGT) — a location that historically made the Persian Gulf a trading crossroads between East and West.
Dubai has transformed into a global business hub in the 21st century, hosting regional headquarters for hundreds of multinational corporations, a major international airline (Emirates), and one of the world's busiest airports by international passenger traffic. The Dubai Financial Market (DFM) and Abu Dhabi Securities Exchange (ADX) operate Sunday to Thursday — the UAE workweek runs Sunday through Thursday, with Friday and Saturday as the weekend (though some private companies use Monday–Friday). This creates a narrow window of weekday overlap with European and American counterparts: Sunday in Dubai is a workday while Europe is on weekend, and Thursday in Dubai ends before much of the Americas starts its week.
The lack of DST means Dubai's offset to summer-time Europe briefly narrows: when London is on BST (UTC+1) in summer, London–Dubai difference is only 3 hours instead of 4. When New York is on EDT (UTC−4) in summer, the New York–Dubai gap narrows from 9 to 8 hours. These changes are on the other parties' side, but awareness is important for anyone scheduling across the Dubai–Europe or Dubai–Americas boundary.
Dubai is currently 5 hours behind Tokyo.
When it is 12:00 noon in Tokyo, it is 07:00 in Dubai (based on current offsets — verify during DST transitions).
