There is no time difference between Jeddah and Riyadh. Both cities use Arabia Standard Time (AST, UTC+3). When it's 9:00 AM in Jeddah, it's also 9:00 AM in Riyadh.
Saudi Arabia uses a single timezone across the entire country and does not observe daylight saving time.
Any time works! Since both cities share the same timezone, you can schedule calls during standard business hours (9:00 AM - 5:00 PM) without any time conversion needed.
Jeddah and Riyadh are Saudi Arabia's two largest cities, connected by a 1.5-hour flight or the Haramain high-speed railway. Riyadh is the capital and political center, while Jeddah is the commercial hub and gateway for pilgrims visiting Mecca.
