City time versus fixed abbreviations

New York, Chicago, Denver, and Los Angeles are date-aware city zones. They can switch between standard and daylight time during the year.

EST, CST, MST, and PST pages use fixed standard-time offsets. Use these only when the abbreviation is explicitly required; use a city route for present-day schedules.

Questions

Time converter FAQ

Does this time zone converter account for daylight saving time?

City routes use IANA time-zone rules for the date entered. Fixed abbreviation routes such as EST and PST remain at their stated standard-time offset throughout the year.

Is GMT the same as UTC?

For ordinary civil-time conversion, both are represented as offset +00:00 here. UTC is the modern time standard, while GMT is a historical time-zone term.

Why can the time difference between two cities change?

Countries can start daylight saving time on different dates, end it on different dates, or not observe it at all. Date-aware city zones capture those changes.
