The Saudi working week
Saudi Arabia’s weekend is Friday and Saturday, so the business week runs Sunday to Thursday. That leaves three days of overlap with Europe and the US (Monday to Thursday) and makes Sunday a working day in Riyadh but not in London.
The Saudi stock exchange (Tadawul) trades from 10:00 to 15:00, Sunday to Thursday.
Riyadh and its neighbours
Riyadh shares UTC+3 with Doha, Kuwait City and Manama, and is one hour behind Dubai and Abu Dhabi. In winter it is three hours ahead of London; during British Summer Time, two hours.
