Oslo is 7 hours ahead of Dallas. When it's 9:00 AM in Dallas, it's 4:00 PM in Oslo. Both cities observe DST on similar schedules.
Dallas uses CT (Central Time) while Oslo uses CET (Central European Time). The time difference stays consistent year-round as both regions adjust their clocks together.
Optimal window: 7:00 AM - 9:00 AM Dallas time (2:00 PM - 4:00 PM Oslo). Early morning calls from Dallas reach evening hours in Oslo.
This 7 hours difference requires flexibility. Many Dallas professionals in energy, telecommunications, and technology start early to collaborate with Oslo's energy, shipping, and technology teams before they end their workday.
