Daylight saving time guide
When does DST end?
DST end dates differ by country. The US, UK and Europe do not always change on the same Sunday, so meetings can shift by one hour.
Quick answer
Live IANA timezone check
This page uses America/New_York, not a fixed abbreviation, so the browser's IANA timezone database can show the current short name and UTC offset.
Why end dates matter
For one or two weeks each year, US and European offsets can be different from the usual pattern. A 9 AM New York call may land one hour differently in London, Paris or Berlin.
How to plan recurring meetings
Before March and October/November, re-check recurring cross-border calls with a date-aware converter. Avoid fixed labels such as EST, PST, GMT or CET for future dates.
For precise scheduling, use the IANA timezone such as America/New_York and a real calendar date. Abbreviations are helpful labels, but they can be ambiguous and change with daylight saving time.
