The weekend is Friday–Saturday
The UAE shifted to a Saturday–Sunday weekend for government in 2022, but many private companies still observe Friday–Saturday. Always confirm.
Tip: Friday afternoon is sacred for prayers. Many businesses close 12–2pm on Fridays.
AC is life
Temperatures hit 50°C in summer. Everything is air-conditioned — malls, cars, bus stops, even some outdoor spaces. Nobody walks outside June–September unless they have to.
Cash is fading
Cards and Apple Pay work almost everywhere. But keep some cash for older cafeterias, souks, and parking meters. ATMs are plentiful.
