Las Vegas is typically 8 hours behind London. When it's 5:00 PM in London, it's 9:00 AM in Las Vegas. Both cities observe daylight saving time, though the transition dates differ slightly.
During the brief periods when the US and UK change clocks on different weekends (usually in March and November), the difference can temporarily be 7 or 9 hours. For most of the year, it's a consistent 8-hour difference.
Optimal meeting window: 6:00 AM - 9:00 AM Las Vegas time (2:00 PM - 5:00 PM London). This catches afternoon business hours in London while being early morning in Las Vegas.
Convention and entertainment industry professionals often schedule UK calls during this window.
