When do clocks go back?

Fall-back dates depend on the country and year. Most of Europe and the UK change clocks on a late-October Sunday, while the United States and Canada usually follow on the first Sunday in November. Use the worldwide schedule on this page for each region's exact local transition date and time.

What happens to US–Europe meeting times during the DST overlap week?

When Europe has already fallen back but most of the US and Canada are still on daylight time, transatlantic time gaps shrink by one hour for that week. A recurring meeting booked for a fixed local hour in one city may land at a different hour in the other until the US fall-back catches up.

What is daylight saving time and how does it work?

Daylight saving time (DST) is a seasonal clock change used by some countries and regions. At the start of DST, clocks usually move forward by one hour; when DST ends, clocks usually move back by one hour. The exact date, local time, and size of the change depend on the location.

When do the clocks change?

Clock-change dates depend on the country, region, and year. North America and Europe normally change on different weekends, while Southern Hemisphere changes occur in opposite seasons. Use the worldwide schedule on this page for each location's exact local transition date and time.

Do all countries use daylight saving time?

No. Many countries keep one standard UTC offset all year. Some countries observe DST nationwide, some use it only in selected regions, and others do not change their clocks at all.

What do spring forward and fall back mean?

Spring forward means clocks move ahead when daylight saving time begins, creating a skipped local hour. Fall back means clocks move backward when daylight saving time ends, causing one local hour to repeat. A few locations use changes other than one hour.

Does UTC change when daylight saving time starts or ends?

No. Coordinated Universal Time (UTC) does not change for daylight saving time. The local UTC offset changes instead. For example, a location may move from UTC-5 to UTC-4 when its clocks move forward.

How does DST change the time difference between two places?

When one place changes clocks before another, the time difference between them can temporarily increase or decrease. Recurring international meetings should be checked against the DST rules in effect on each meeting date.

What do EST, EDT, GMT, and BST mean?

These are time zone abbreviations. EST is a standard-time label, EDT and BST identify daylight or summer time, and GMT is a fixed UTC+0 reference that is also used as standard time in some places. Read an abbreviation together with its UTC offset and location because some abbreviations are used by more than one time zone.

Is it daylight saving time or daylight savings time?

The official term is daylight saving time, without an s after saving. Daylight savings time is a common informal phrase and usually refers to the same seasonal clock-change practice.
