Riyadh Time Zone: Arabia Standard Time (AST, UTC+3)
Riyadh and all of Saudi Arabia operate on Arabia Standard Time (AST), which is UTC+3 year-round. Saudi Arabia does not observe daylight saving time, so the UTC offset stays fixed at +3 regardless of the season. This makes it straightforward to calculate time differences with Riyadh throughout the year.
AST (UTC+3) is shared with several neighbouring countries: Kuwait, Qatar, Bahrain, and Yemen all use the same UTC+3 offset. This makes the entire core Gulf Cooperation Council (GCC) region — except the UAE and Oman (UTC+4) — operate on the same clock as Riyadh.
Riyadh Business Hours and the Saudi Working Week
Saudi Arabia officially moved to a Monday–Friday working week for government and most businesses in 2013, aligning with international norms. Standard government and bank hours are 7:30 AM to 3:30 PM AST. Private sector companies typically work 9:00 AM to 6:00 PM, with a midday break in some traditional businesses.
During Ramadan, working hours are legally shortened. Government employees work 6 hours per day, and many private businesses reduce to a 6-hour day as well. Friday remains a day of special significance — Friday prayers (Jumu'ah) typically take place around midday, and many businesses close or reduce hours on Friday afternoons.
