Frequently asked questions

Q: What is a time zone?
A: A time zone is a region of the Earth that observes a uniform standard time for legal, commercial, and social purposes. The world is divided into 24 primary time zones, each roughly 15 degrees of longitude wide, corresponding to one hour of difference from Coordinated Universal Time (UTC). In practice, time zone boundaries follow political and geographical lines rather than perfect geometric divisions.

Q: What is UTC and how does it relate to time zones?
A: UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks and time. All other time zones are expressed as offsets from UTC — for example, Eastern Time in the US is UTC−5 in winter (EST) and UTC−4 in summer (EDT) during Daylight Saving Time. UTC itself does not change for Daylight Saving Time, making it the universal reference point for scheduling across time zones.

Q: How does Daylight Saving Time affect time zone conversions?
A: Daylight Saving Time shifts clocks forward one hour in spring and back one hour in fall in participating regions, which changes the UTC offset for those time zones. Not all countries observe DST — most of Asia, Africa, and parts of South America do not. This converter uses your browser's time zone data which accounts for DST automatically.

Q: What time zone should I use for scheduling international meetings?
A: For international meetings, it is common to reference UTC or to schedule relative to a shared anchor city such as London or New York. Calendar applications like Google Calendar and Outlook automatically convert meeting times to each participant's local time zone when the event is created with a time zone specified.

Q: Why is it a different day in some parts of the world?
A: The International Date Line runs approximately along the 180th meridian in the Pacific Ocean. When you cross it traveling westward, you move forward one calendar day. This is why locations in Asia such as Japan and Australia are already in the next calendar day when it is still afternoon in the United States.
