Business & Commerce

Vienna, Austria's capital, operates on Central European Time (CET, UTC+1) in winter and Central European Summer Time (CEST, UTC+2) from late March through late October. Vienna functions as one of Central Europe's most important business gateways, particularly between Western and Eastern Europe, and as a hub for multilateral institutions. Most notably, Vienna has been the headquarters of OPEC's secretariat since 1965: OPEC ministerial conferences held in Vienna are among the most market-moving events in global commodity markets, with oil production decisions announced from the city capable of shifting energy prices worldwide within hours. The Vienna Stock Exchange (Wiener Börse) rounds out the city's financial profile. At CET/CEST, Vienna is one hour ahead of London and typically six hours ahead of New York.
