Understanding Daylight Saving Time Across the Globe
A memorable experience on a chilly evening in London highlighted the complexities of daylight saving time (DST). While enjoying a glass of wine in a Bermondsey bar, I inadvertently learned that not all countries adjust their clocks at the same time. My casual scrolling revealed a crucial scheduling detail: the UK shifts its clocks forward on the last Sunday in March, a full hour behind my home city of New York, where the change had already taken place on the second Sunday in March.
To avoid the kind of confusion I experienced, it’s vital for travelers to familiarize themselves with DST schedules, especially when navigating international time zones. For example, many states in the U.S. readjusted their clocks on November 1.

Countries across the globe observe DST on various dates, or in some cases, not at all. Most European nations follow a similar schedule to the UK, clocking forward in March and back in October. However, it’s essential to check the specific DST practices of your destination, as approximately two-thirds of the world does not observe this practice, according to Pew Research Center.
While North America and parts of Europe largely participate in DST, several countries such as Armenia, Belarus, and Turkey maintain standard time throughout the year. In 2023, Egypt was notable for reintroducing DST for the first time in seven years, moving its clocks forward on the last Friday of April.
Daylight Saving Time Disparities Within the U.S.

Traveling within the United States requires similar vigilance. DST is adhered to in 48 states from the second Sunday in March to the first Sunday in November. However, Arizona and Hawaii do not adjust their clocks, which may lead to timing issues, particularly for Arizona, which borders states that do observe DST.
According to Becky Blaine, a travel expert, “It’s crucial to verify the timing when flying in and out of Arizona, as miscalculations can lead to missed flights and other mishaps.” Remember, Arizona operates under Pacific Daylight Time from mid-March to early November, reverting to Mountain Standard Time at other times of the year.
Unique Time Zone Practices in Canada and Australia
In Canada, many regions align with the U.S. DST calendar, while others, such as parts of Saskatchewan and the Yukon, remain on standard time year-round. Australia also presents variances, with DST beginning on the first Sunday in October in certain states, while others like Queensland and Western Australia do not follow the practice.
Private Resorts and Local Time Zones

While not directly related to DST, certain destinations, like the Maldives, present additional challenges with time zones. Notably, some island resorts operate on a different time than the local airport to enhance guests’ enjoyment of evening daylight. Travelers should always check their resort’s local time practices to avoid unintended delays.
Half-Hour Time Zones: A Unique Challenge

Newfoundland operates on a 30-minute difference from the Atlantic Time Zone, which can add confusion for those traveling across Canada. Similar half-hour offsets exist in India, Sri Lanka, and Australia, while Nepal presents an even more unusual offset of 45 minutes.
Managing Calendar Events While Traveling
Travelers must stay alert to potential errors when adding events to digital calendars. For instance, entering a calendar event while in a different time zone can lead to misalignment when returning home. Experts recommend toggling time zone settings in calendar applications to prevent this common oversight.
Time Adjustments on Cruises: Stay Informed
Cruising can introduce multiple time zone changes in quick succession, particularly on transoceanic journeys. Passengers should be aware of time shifts to avoid missing important events. Cruise lines generally provide notifications about time changes, but relying solely on your phone may lead to errors. It’s advisable to carry a manual timepiece for double-checking time accuracy.
Conclusion: Navigate Time Zones Wisely
When journeying across borders or even state lines, travelers should not assume uniformity in DST practices. Awareness of local time conventions can prevent disappointments, such as missed flights or last-minute surprises.
