Timezone Converter - Convert Time Between 31 World Time Zones

What happens at 3 PM in Warsaw when your call is at 9 AM in New York

Pick a date and time, choose the source zone, pick the target zone - and the converter shows the exact result with UTC offsets and the hour gap between the two locations. It covers 31 time zones across Europe, North and South America, Asia, Australia, Africa and UTC. Daylight saving time shifts are handled by the browser's built-in Intl engine, so the result reflects the actual offset on that specific date.

How to use the Timezone Converter - step by step

Date and time - enter the date and time you want to convert (e.g. 2026-06-26 15:00 for 3 PM on June 26).
Source time zone - select the zone the entered time belongs to (e.g. Warsaw for Central European Time).
Target time zone - select the zone you want to convert to (e.g. New York for Eastern Time).
Read the results - the converter displays both times side by side with weekday, date, UTC offset and the hour difference.

Common time zone differences

These offsets apply during summer (DST active in both locations where applicable):

From	To	Difference (summer)	Difference (winter)
London	New York	-5h	-5h
Warsaw	New York	-6h	-6h
New York	Los Angeles	-3h	-3h
London	Tokyo	+8h	+9h
New York	Sydney	+14h	+16h
Dubai	Singapore	+4h	+4h

Practical examples

Example 1: Meeting at 3:00 PM Warsaw time. In New York that is 9:00 AM (EDT, -6h). Both on the same day (Thursday).

Example 2: Flight lands in Tokyo at 11:45 AM local time. Back in London it is 3:45 AM the same day (-8h in summer).

Example 3: 11:00 PM Friday in Los Angeles = 2:00 PM Saturday in Sydney (+17h in winter). The date changes across the International Date Line.

Example 4: 9:30 AM Delhi (UTC+5:30) = 5:00 AM Warsaw (UTC+1, winter) or 6:00 AM Warsaw (UTC+2, summer). The half-hour offset makes Delhi conversions tricky.

Example 5: 12:00 PM UTC (noon) = 8:00 AM New York (EDT), 2:00 PM Warsaw (CEST), 9:00 PM Tokyo (JST). UTC is the universal anchor.

About daylight saving time (DST)

Not all time zones observe DST. Tokyo, Dubai, Singapore and most of Africa stay on the same offset year-round. Europe switches clocks on the last Sunday of March and October. The US switches on the second Sunday of March and the first Sunday of November. During the two-to-three-week gap when one region has switched and the other has not, the hour difference is temporarily 1 hour more or less than usual.

Region	DST starts	DST ends	Observes DST?
US / Canada	2nd Sun March	1st Sun November	Yes
Europe	Last Sun March	Last Sun October	Yes
Australia (Sydney)	1st Sun October	1st Sun April	Yes
Japan / Korea	-	-	No
Dubai / Singapore	-	-	No

FAQ - Frequently asked questions

Does the converter handle daylight saving time automatically?

Yes. The converter uses the browser's built-in Intl.DateTimeFormat API, which knows the DST rules for every time zone. If you enter a date in July, it applies summer offsets. If you enter January, it applies winter offsets. No manual adjustment needed.

What is UTC and why does it matter?

UTC (Coordinated Universal Time) is the global reference. All other time zones are defined as offsets from UTC. New York is UTC-5 in winter, UTC-4 in summer. Tokyo is always UTC+9. Using UTC removes ambiguity when scheduling across zones.

Can the date change during conversion?

Yes. If you convert 11 PM Friday in New York to Tokyo (+13h), the result is 12 PM Saturday in Tokyo. The converter shows both the date and weekday so you can see when the day rolls over.

Why is Delhi offset by 30 minutes instead of a full hour?

India Standard Time is UTC+5:30 - one of several zones with a half-hour offset. Nepal is UTC+5:45. The converter handles these non-standard offsets correctly.

How many time zones are supported?

31 zones covering major cities on every continent: 8 European, 9 American, 9 Asian, 2 Australian, 1 Oceanian, 2 African and UTC.

What is the difference between GMT and UTC?

For practical purposes, they are identical - both represent the zero offset. Technically, GMT is a time zone (used in the UK in winter), while UTC is a time standard based on atomic clocks. This converter uses UTC as the reference.
