World Clock — Current Time Around the World

Why a World Clock Matters

Remote teams, family abroad, international markets and global sports fixtures all run into the same problem: "what time is it there right now?" A world clock answers that instantly, and more importantly it answers it correctly — including the daylight saving shifts that catch people out twice a year.

VClock reads time zone rules from the IANA database built into your browser, the same source operating systems use. That means Phoenix stays on Mountain Standard Time all year while Denver switches, London and New York change DST on different weekends, and India stays 30 minutes offset from its neighbours — all without you configuring anything.

US Time Zones at a Glance

Zone	Standard	Daylight	Example cities
Eastern	UTC−5	UTC−4	New York, Miami, Atlanta, Boston
Central	UTC−6	UTC−5	Chicago, Dallas, Houston, New Orleans
Mountain	UTC−7	UTC−6	Denver, Salt Lake City, Albuquerque
Mountain (no DST)	UTC−7	UTC−7	Phoenix, most of Arizona
Pacific	UTC−8	UTC−7	Los Angeles, Seattle, San Francisco
Alaska	UTC−9	UTC−8	Anchorage, Juneau
Hawaii–Aleutian	UTC−10	UTC−10	Honolulu (no DST)

In the United States, daylight saving currently begins on the second Sunday in March and ends on the first Sunday in November. Hawaii and most of Arizona do not observe it at all, which is why a call that works in July may not work in January.

Scheduling Across Time Zones Without Mistakes

• Always name the zone. "3 PM ET" removes ambiguity that "3 PM" creates.
• Watch the date line. A Friday afternoon meeting in New York is Saturday morning in Sydney — check the date on each card, not just the hour.
• Beware the DST gap. For three weeks in March and one in November, the US and Europe are one hour closer or further apart than usual. Recurring meetings drift during these windows.
• Find the overlap first. Add every participant's city, then look for hours that sit between roughly 9 AM and 6 PM on all cards at once.
• Use UTC for records. Logs, deadlines and contracts are far less error-prone when written in UTC.

How Time Zones Work

The world is divided into zones offset from Coordinated Universal Time (UTC), the modern successor to Greenwich Mean Time. In theory each zone is one hour wide; in practice borders follow political lines, and several regions use 30- or 45-minute offsets — India is UTC+5:30, Nepal UTC+5:45, and parts of Australia UTC+9:30. Add seasonal daylight saving, which about a third of the world observes on its own schedule, and manual conversion becomes genuinely error-prone. That is exactly the arithmetic a world clock removes.
