In this article, we’ll delve into Los Angeles’ time zone, explore time differences with major cities around the globe, answer frequently asked questions, and provide clarity on the subject.
Time Zone of LA
LA operates within the Pacific Time Zone (PT). The Pacific Time Zone is eight hours behind Coordinated Universal Time (UTC-8) during standard time. However, during Daylight Saving Time (DST), LA adjusts its clocks forward by one hour, moving to UTC-7.
The Pacific Time Zone encompasses much of the western United States, including states like California, Oregon, and Washington. This time zone can vary depending on whether it’s daylight saving or standard time.
- Pacific Standard Time (PST): UTC-8 (Late Fall to Winter)
- Pacific Daylight Time (PDT): UTC-7 (Spring to Early Fall)
Daylight Saving Time in Los Angeles
Daylight Saving Time (DST) in LA begins on the second Sunday in March, when clocks are moved forward one hour, and ends on the first Sunday in November, when clocks revert to standard time. This adjustment is made to extend daylight hours into the evening and conserve energy. As a result, Los Angeles operates on Pacific Daylight Time (PDT) during the summer months.
Key Dates:
- Start of DST: Second Sunday in March (clocks move forward by one hour)
- End of DST: First Sunday in November (clocks move back by one hour)

Time Difference During Business Hours
One of the most important factors is the time difference during typical business hours (9:00 AM to 5:00 PM) in Los Angeles. Knowing when business hours overlap between cities helps schedule meetings, video calls, and productive communication.
For example:
New York: If it’s 9:00 AM in LA, it’s already noon in New York. The business day in New York starts three hours earlier.
London: Los Angeles is typically eight hours behind London. If it’s 9:00 AM in Los Angeles, it’s 5:00 PM in London, meaning businesses in London are finishing their day.
Tokyo: The time difference is substantial with Tokyo, at 17 hours ahead of Los Angeles. When it’s 9:00 AM in LA, it’s already 2:00 AM the next day in Tokyo.
International Flights and Time Changes
For those flying internationally, understanding the time difference is vital for adjusting your schedule and avoiding jet lag. For example, flights from LA to Sydney, Australia, often cross multiple time zones, with a time difference of 19 hours.
Los Angeles to Sydney: If you depart LA at 10:00 PM PST on a Tuesday, you will arrive in Sydney approximately 14 hours later, but the local time in Sydney will be around 3:00 AM on Thursday due to the 19-hour time difference.
Los Angeles to London: A flight from LA to London typically takes about 10 hours, but with an eight-hour time difference, you’ll arrive the next day in the early afternoon or late morning.
Understanding these time zone changes ensures better planning for flights, especially when it comes to making connections or attending business meetings.
Time Zones and Communication
In today’s globalized world, businesses, travellers, and remote workers often need to communicate across time zones. Here’s how the LA time difference might impact communication with major global regions:
Europe: As LA is typically 8-9 hours behind Europe, scheduling calls and meetings early in the morning in Los Angeles is important, as it’s already late afternoon or evening in Europe.
Asia: LA is around 16-17 hours behind much of Asia, including China, Japan, and South Korea. This means scheduling calls with Asia often requires early morning or late evening hours in Los Angeles.
Australia and Oceania: Sydney is 19 hours ahead of LA, which means coordinating with contacts in Australia requires careful scheduling, often for late evening or early morning calls.
