9am in Riyadh is 2am in New York City

When it’s 9am in New York City, it’s 5pm in Riyadh. Riyadh is 8 hours ahead from New York City, placing United States and Saudi Arabia far enough apart to require deliberate scheduling. The best window for live calls is 8am to 10am in New York City (4pm to 6pm in Riyadh). Corporate travelers and deal-makers on the New York City-Riyadh route schedule calls during the shared business-hours window to avoid after-hours meetings on either side. Financial and trade connections between United States and Saudi Arabia concentrate activity in that overlap window. The wide gap means one city is often asleep while the other is fully active, so asynchronous tools carry most of the daily communication load. New York City observes daylight saving time while Riyadh does not, so the offset narrows by one hour when United States clocks spring forward. Keeping a timezone converter bookmarked helps both sides quickly verify the current time in Riyadh before sending a calendar invite.
