Understanding UTC Offsets

Every time zone is expressed as an offset from UTC — the number of hours (and sometimes half-hours) added or subtracted. For example, UTC+5:30 is India Standard Time, which is 5 hours and 30 minutes ahead of UTC.

Offsets can be negative (the Americas are mostly west of UTC), zero (London in winter), or positive (Europe, Asia, and the Pacific). Some countries use non-standard half-hour or quarter-hour offsets — India (+5:30), Iran (+3:30), and Nepal (+5:45) are common examples.

Americas

UTC−12 to UTC−3. Most of the US uses UTC−5 (EST) or UTC−8 (PST) in winter.

Europe & Africa

UTC−1 to UTC+4. Central Europe is UTC+1 (CET) in winter, UTC+2 in summer.

Asia & Pacific

UTC+3 to UTC+14. Japan (UTC+9) and Australia (UTC+10/11) are common destinations.

Frequently Asked Questions

How do I convert time between time zones?▾
Select two time zones from the dropdowns above. The tool shows the current local time in both zones and calculates the time difference automatically. For a specific time, enter it in the "Convert a specific time" field.
What is UTC?▾
UTC (Coordinated Universal Time) is the global time standard. All time zones are defined as UTC plus or minus an offset. For example, New York is UTC-5 (EST) or UTC-4 (EDT) during daylight saving time. UTC never observes daylight saving.
What is the difference between UTC and GMT?▾
For everyday purposes, UTC and GMT (Greenwich Mean Time) are interchangeable — both represent the same time with zero offset. Technically, UTC is an atomic time standard while GMT is based on solar time. UTC replaced GMT as the civil time standard in 1972.
How does daylight saving time affect conversions?▾
The converter uses your browser's clock and the IANA timezone database, which accounts for daylight saving time (DST) automatically. When a region observes DST, its offset from UTC shifts by 1 hour. Not all countries observe DST — the US, most of Europe, and Australia do; Japan, China, India, and most of Africa do not.
What time is it in [city] right now?▾
Select that city's timezone from the dropdown to see the current local time. The display updates every second from your system clock.
What is the best time to schedule an international meeting?▾
A typical overlap for US/Europe is 3–5 PM CET (9–11 AM EST). For US/Asia, there is often no business-hours overlap — someone must take an early or late call. Use this converter to find a time that falls within 9 AM–6 PM for all participants.
Why do some cities change UTC offset at different dates?▾
Daylight saving time transitions happen on different dates by country. The US shifts on the second Sunday in March; Europe shifts on the last Sunday in March. This creates a 1–3 week period each spring and fall when the offset between US and European cities differs from the rest of the year.
