Convert time between different time zones. Perfect for remote work and international meetings.
The Time Zone Converter is a free, browser-based tool that lets you instantly convert any date and time between more than 50 major time zones around the world. Whether you are scheduling a meeting with a remote team, planning international travel, or coordinating a live event for a global audience, this tool gives you accurate conversions in seconds.
A time zone converter takes a specific date and time in one time zone and calculates the equivalent moment in one or more other time zones. Because the world is divided into dozens of time zones — each offset from Coordinated Universal Time (UTC) by a different number of hours and minutes — converting between them manually is error-prone and tedious. A dedicated tool eliminates that friction entirely.
This tool also handles Daylight Saving Time (DST) automatically. Many countries shift their clocks forward or backward by one hour at certain points in the year, which means the offset between two time zones can change depending on the date. The converter uses your browser's built-in Intl API to apply the correct DST rules for each zone on the date you specify.
Beyond simple one-to-one conversion, the tool includes a multi-zone comparison panel where you can add several time zones and see the current time in all of them simultaneously. This is invaluable for distributed teams that need a quick reference for where their colleagues are in the day.
When scheduling meetings, always double-check dates near Daylight Saving Time transitions. In the days around when clocks change, the offset between two zones can shift by an hour, which can cause confusion if you calculated the meeting time a week in advance. This tool applies DST rules automatically based on the exact date you enter, so it will always give you the correct result.
Use the comparison panel to build a persistent reference for your most-used time zones. Add your team's locations once and you can see everyone's current local time at a glance without needing to convert each one individually. The panel updates in real time as the clock ticks.
For UTC-based work such as server administration or API logging, set the "To" zone to UTC and use the tool to quickly translate any local time into its UTC equivalent. This is a common need for developers and DevOps engineers who work with timestamps in logs, databases, and monitoring systems.
Time calculations run in your browser using the Intl API. No data is transmitted.
Select the source time zone, enter the time, then select the target time zone. The converter instantly shows the equivalent time. You can add multiple time zones to compare them all at once.
UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks. It has no daylight saving time adjustments. All time zones are defined as offsets from UTC (e.g., EST is UTC-5, IST is UTC+5:30). Using UTC as a reference avoids ambiguity.
The converter accounts for daylight saving time (DST) automatically based on the selected date. A time zone like EST (UTC-5) becomes EDT (UTC-4) during summer. Always specify the date when converting times near DST transitions to get accurate results.
GMT (Greenwich Mean Time) and UTC are nearly identical for practical purposes. GMT is a time zone; UTC is a time standard. The difference is at most 0.9 seconds. In everyday use, they are interchangeable. UTC is preferred in technical contexts.
Enter the proposed meeting time in your local time zone and add all participants' time zones. The converter shows what time it will be for each person. Aim for times that fall within business hours (9 AM - 6 PM) for all participants when possible.
