Oklahoma operates on Central Standard Time (CST) during winter months, which is 6 hours behind Coordinated Universal Time (UTC-6). During daylight saving time, observed from the second Sunday in March to the first Sunday in November, Oklahoma switches to Central Daylight Time (CDT), which is UTC-5.
All of Oklahoma follows the same time zone. Major cities including Oklahoma City, Tulsa, Norman, Broken Arrow, and Edmond all observe Central Time. This makes scheduling across Oklahoma straightforward, as there's no time difference within the state.
Oklahoma is a major energy hub in Central Time. When it's 9 AM in Oklahoma City, it's 10 AM in New York and 4 PM in Dubai. Oklahoma's energy sector coordinates oil and gas trading across multiple global time zones.
