An International Expo is held in one of the years between two World Expos, and lasts for 3 months (for example Yeosu, South Korea in 2012).
A World Expo (exposition) is held every 5 years, in years ending with a '0' or a '5', and lasts for 6 months. There are two types of world fairs or exhibitions. A bit like comparing IMG World or Motiongate to Stargate in Zabeel Park.
What is a World Exposition? For UAE residents familiar with Global Village, a World Expo is similar but with more air conditioning, more lights, higher ticket prices, more restaurants, more stuff to look at, and not so many baskets or leather jackets for sale. It is the first time a World Expo is held in the Middle East. Dubai (the city and emirate) in the UAE (the country), will be the host city for the 2020 World Expo exhibition, held from October 2020 to April 2021, with the theme slogan 'Connecting Minds, Creating the Future'.
