First, the basics
So what exactly is "Dubai" — a city, or a country?
Short answerDubai is a city and an emirate — one of seven that make up the United Arab Emirates. The country sits on the Arabian Peninsula, on the Persian (Arabian) Gulf, next to Saudi Arabia and Oman.
People say "I'm going to Dubai" the way they'd say "I'm going to New York", but it helps to know the frame around it. The United Arab Emirates was formed in 1971 as a union of emirates, each historically its own sheikhdom. Abu Dhabi is the federal capital and the largest emirate by area; Dubai is the best-known internationally and the commercial and tourism engine.
The official language is Arabic, but English is spoken almost everywhere — on signs, in shops, in taxis and hotels — because the population is famously international, with residents from across the world. The currency is the UAE dirham (AED), and the country is known for safety, modern infrastructure and a year-round sunny climate.
Good to know: the working week is Monday to Friday, with Friday a shorter day and the weekend on Saturday and Sunday, in line with most international business.
