Why Time Zones Matter
In our connected world, time zones are more important than ever. Whether you're scheduling a video call with colleagues across the globe, planning a trip to another country, working with remote teams, or coordinating international events, accurately converting time between different time zones is essential. Manual time zone conversion is error-prone, especially when dealing with daylight saving time changes, which vary by country and region.
Our free online time zone converter makes it easy to convert time between any two cities or time zones instantly. The tool automatically accounts for daylight saving time (DST) adjustments, works with both past and future dates, and provides accurate conversions for locations worldwide. It's completely free, requires no registration, and works entirely in your browser—no data is sent to servers, ensuring complete privacy.
The converter supports over 25 major cities and time zones, including New York, London, Tokyo, Sydney, and more. You can convert current time, or enter any specific date and time to see what it would be in another timezone. Perfect for global business, travel planning, and international communication.
How to Use the Time Zone Converter
Using our time zone converter is simple and straightforward:
- Select your current city or time zone: Choose the timezone you're starting from using the "From Timezone" dropdown. You can select from major cities like New York, London, Tokyo, or any other supported timezone.
- Select the target city or time zone: Choose the timezone you want to convert to using the "To Timezone" dropdown.
- Enter the date and time (optional): If you want to convert a specific date and time, enter it in the date-time field. You can also check "Use current time" to instantly convert the current moment.
- Click "Convert Time": The converter will instantly display the converted time in both timezones, along with the time difference.
Examples:
- Convert New York 3 PM to London time: Select "New York" as source, "London" as target, enter 3:00 PM, and convert. During EST, New York is 5 hours behind London, so 3 PM EST becomes 8 PM GMT/BST.
- Convert Tokyo 9 AM to Sydney time: Select "Tokyo" as source, "Sydney" as target, enter 9:00 AM, and convert. Tokyo is typically 1 hour behind Sydney, so 9 AM JST becomes 10 AM AEST.

Frequently Asked Questions
How do I convert time zones?
Select the source time zone from "From Timezone" and the target from "To Timezone". Enter the date and time (or check "Use current time"), then click "Convert Time". You get the equivalent time in the other time zone and the time difference. Use it as a world clock to compare multiple places.
What is a world clock?
A world clock shows the same moment in time across different time zones. Our time zone converter works like a world clock: pick two places (or time zones), enter a time, and see what that time is in the other place. Use it to schedule calls, plan travel, or coordinate with teams in other countries.
Does the converter account for daylight saving time?
Yes! Our time zone converter automatically accounts for daylight saving time (DST) adjustments. When you select a date and time, the converter uses the correct DST rules for that specific date. For example, New York switches between EST (UTC-5) in winter and EDT (UTC-4) in summer, and the converter handles this automatically. This ensures accurate conversions year-round, regardless of when DST changes occur.
Can I calculate time differences for future dates?
Absolutely! You can convert time for any date—past, present, or future. Simply enter the date and time you want to convert, and the converter will show you what that time would be in another timezone. This is perfect for planning meetings, scheduling events, or calculating times for future travel. The converter accounts for DST rules that will be in effect on that date, ensuring accuracy even for dates far in the future.

Yes! Our time zone converter is completely free to use. There's no registration required, no hidden fees, and no usage limits.
