Paris is UTC+1 (GMT+1) / UTC+2 (GMT+2). Hong Kong is UTC+8 (GMT+8, no DST). Hong Kong is currently 6 hours ahead of Paris.
Best times to meet (Paris local time): 9:00 AM — 3:00 PM in Hong Kong; 10:00 AM — 4:00 PM in Hong Kong.

Paris operates on Central European Time (CET, UTC+1) in winter and Central European Summer Time (CEST, UTC+2) from the last Sunday in March to the last Sunday in October. France's adoption of CET in 1940 during the German occupation aligned the country with Berlin time, replacing an earlier French legal time of UTC+0:09:21 (the Paris meridian). After the war, France retained CET rather than reverting, making Paris permanently one hour ahead of London in winter despite being geographically close to the GMT meridian.
Paris is the financial centre of continental Europe and hosts many major EU institutions, international organisations, and multinational headquarters. French business hours typically run 09:00–18:00 CET/CEST, with a longer lunch break than Anglo-American norms. Being in the same timezone as most of continental Europe (Germany, Italy, Spain, the Netherlands, Sweden, and more all use CET/CEST) means that Paris aligns perfectly with its major trading partners. It is one hour ahead of London in winter but shares the same UTC+1 offset as London during British Summer Time — a period when "Paris time" and "London time" temporarily converge.
French law mandates that meetings involving public agencies begin no earlier than 08:00 and end by 20:00 local time. The European Union has been debating abolishing seasonal clock changes since 2019, with member states unable to agree on whether to stay on permanent standard time or permanent summer time. Until a resolution is reached, EU countries including France continue to change their clocks twice a year in synchrony.
Hong Kong observes Hong Kong Time (HKT, UTC+8) year-round, with no Daylight Saving Time. Hong Kong briefly observed DST during 1941–1945 and 1946, but has not changed its clocks since 1979, when it permanently abandoned the practice. HKT is identical to China Standard Time (CST), Singapore Standard Time (SGT), Malaysia Time (MYT), the Philippines Standard Time (PST), and Western Australia Standard Time (AWST) — all at UTC+8, making it the world's most widely shared standard timezone offset by number of countries and territories.
Hong Kong is one of the world's leading international financial centres. The Hong Kong Stock Exchange (HKEX) operates 09:30–16:00 HKT with a lunch break from 12:00 to 13:00 — making it notable among major exchanges for retaining a midday pause. The daily turnover on HKEX is among the world's highest, and it serves as the primary gateway between China's capital markets and the rest of the world. Hong Kong's UTC+8 position means it opens about 90 minutes after Tokyo (UTC+9) and about an hour before the Shanghai/Shenzhen exchanges, giving it a slightly earlier start in the region.
Hong Kong is 8 hours ahead of London (GMT) in winter and 7 hours ahead when London is on BST, 13 hours ahead of New York (EST) and 12 hours ahead when New York is on EDT. The narrow overlap with European business hours — typically 09:00–10:00 HKT coincides with London's start-of-day arrival — makes Hong Kong–London conference calls a morning Hong Kong ritual for finance professionals. Despite the same UTC+8 offset as Beijing, Hong Kong maintains its own timezone identity and IANA zone (Asia/Hong_Kong), reflecting its distinct administrative status.
Hong Kong is currently 6 hours ahead of Paris.
When it is 12:00 noon in Paris, it is 18:00 in Hong Kong (based on current offsets — verify during DST transitions).
Paris observes DST, changing from GMT+1 to GMT+2. Hong Kong does not observe DST — GMT+8 is used year-round.
