About Our Time Zone Converter

Our free online time zone converter makes it simple to convert times between any two time zones in the world. Whether you're scheduling an international meeting, coordinating with a remote team, or planning a phone call across continents, this tool provides accurate conversions with support for Daylight Saving Time.

Time zones can be confusing, especially when dealing with multiple regions that observe Daylight Saving Time at different dates. Our converter handles all the complexity automatically, giving you accurate results every time. Simply select your source and target time zones, enter the time you want to convert, and get instant results.

Understanding Time Zones

The world is divided into 24 standard time zones, each roughly 15 degrees of longitude wide. The primary reference point is UTC (Coordinated Universal Time), which replaced GMT (Greenwich Mean Time) as the world standard. All time zones are expressed as offsets from UTC, ranging from UTC-12 to UTC+14.

Daylight Saving Time (DST) adds another layer of complexity. Not all countries observe DST, and those that do may start and end it on different dates. For example, the United States changes clocks in March and November, while Europe changes in late March and October. This means the time difference between two locations can vary throughout the year.

Major Time Zones Explained

Eastern Time (ET) covers the US East Coast, including New York, Washington D.C., and Miami. It's UTC-5 during Standard Time and UTC-4 during Daylight Saving Time. This is one of the most important business time zones globally.

Pacific Time (PT) serves the US West Coast, including Los Angeles, San Francisco, and Seattle. It's 3 hours behind Eastern Time, making it UTC-8 (Standard) or UTC-7 (Daylight). Silicon Valley operates on Pacific Time, making it crucial for tech industry scheduling.

Central European Time (CET) covers most of Western Europe, including Paris, Berlin, Rome, and Madrid. It's UTC+1, or UTC+2 during summer. London operates on GMT (UTC+0) or BST (UTC+1), one hour behind mainland Europe.

Japan Standard Time (JST) is UTC+9 and doesn't observe Daylight Saving Time, making calculations consistent year-round. The same applies to Singapore Time (SGT) at UTC+8, which serves as a major business hub for Asia.

Tips for Global Scheduling

When scheduling meetings across multiple time zones, consider finding overlapping business hours. A meeting at 9 AM Eastern (New York) is 2 PM in London and 6 PM in Dubai—workable for all three locations. However, the same meeting would be 10 PM in Tokyo, outside normal business hours.

For teams spanning the US and Asia, consider rotating meeting times to share the inconvenience fairly. Alternatively, use asynchronous communication tools and only hold synchronous meetings when absolutely necessary.

Always specify the time zone when sharing meeting times. Instead of saying "Let's meet at 3 PM," say "Let's meet at 3 PM EST / 8 PM GMT." This prevents confusion and ensures everyone shows up at the right time.

Frequently Asked Questions

How do I convert time between time zones?

To convert time between time zones, select your source time zone (where you are), enter the time you want to convert, then select the target time zone. Our converter automatically calculates the time difference and shows you the converted time, accounting for any Daylight Saving Time differences.

Does the converter account for Daylight Saving Time?

Yes, our time zone converter automatically accounts for Daylight Saving Time (DST) when applicable. The converter uses your browser's built-in timezone database which includes current DST rules for all regions, ensuring accurate conversions throughout the year.

What is UTC and how does it relate to time zones?

UTC (Coordinated Universal Time) is the primary time standard used worldwide. All time zones are defined as offsets from UTC. For example, New York (EST) is UTC-5, meaning it's 5 hours behind UTC. During Daylight Saving Time, it becomes EDT at UTC-4. Using UTC as a reference makes it easier to calculate time differences between any two zones.

How do I schedule a meeting across multiple time zones?

To schedule a meeting across time zones, first choose a time that works for you, then use our converter to see what time that would be in each participant's location. Look for overlapping business hours (typically 9 AM - 6 PM) in all locations. For widely distributed teams, consider rotating meeting times to share the inconvenience fairly.

What's the time difference between New York and London?

London is typically 5 hours ahead of New York. However, this can temporarily become 4 or 6 hours during DST transitions since the US and UK change their clocks on different dates. For a few weeks in spring and fall, the difference may vary. Use our converter for accurate current differences at any time of year.
