If you travel often, you’ve probably had moments when you scheduled a meeting but got the time wrong. It might be morning in one place and late evening in another. This happens because of time zones. Understanding how they work helps avoid confusion and makes trips easier.
What are time zones and why do they exist?
Time zones are a system that keeps time consistent across different regions. They were introduced to simplify transportation, business, and international communication. There are 24 main time zones worldwide, each typically differing by one hour. The starting point is the prime meridian in Greenwich, London, which sets the standard for Coordinated Universal Time (UTC).
Some regions have unusual offsets, such as 30 or 45 minutes, but most follow a full-hour difference. Many countries also adjust clocks for daylight saving time (DST), temporarily shifting the standard offset.
What should you know about PST?
PST (Pacific Standard Time) follows UTC-8. It covers the western part of North America, including California, Nevada, Washington, Oregon, and parts of Canada. Major cities in this zone include Los Angeles, San Francisco, and Vancouver.
However, Pacific Standard Time changes seasonally. From March to November, daylight saving time applies, shifting the region to Pacific Daylight Time (PDT), which is UTC-7. If you're scheduling calls, booking flights, or planning events, it's important to check whether PST or PDT is in effect.
How does time difference affect travelers?
If you fly from London to Los Angeles, the time difference will be either 8 or 7 hours, depending on the season. When it’s noon in the UK, it might be only 4 AM in California. This shift can cause jet lag, where your body struggles to adjust to a new schedule. The greater the time difference, the harder it is to adapt.
Time zones also impact flight bookings, hotel check-ins, and remote work. A miscalculation could mean missing an important event or arriving at the airport on the wrong day.
How to manage time differences
Use online time converters to quickly check the difference between time zones
Check seasonal changes since some regions observe daylight saving time while others don’t
Set reminders for calls or meetings in different time zones to avoid missing them
Adjust your schedule in advance by gradually shifting your sleep pattern a few days before traveling
Conclusion
Understanding time zones helps travelers stay organized and avoid unnecessary stress. PST is a key time zone for anyone visiting the US or working with companies in California. Keeping track of time differences and seasonal shifts makes travel planning easier and schedules more predictable.
