About Timezone Converter
Our Timezone Converter makes it easy to convert any date and time from one timezone to another. Whether you're scheduling an international meeting, planning travel across time zones, or coordinating with a global team, this tool provides instant and accurate conversions.
The converter supports 20+ major timezones spanning all continents, including US time zones (Eastern, Central, Mountain, Pacific, Alaska, Hawaii), European timezones (London, Paris, Berlin, Moscow), Asian timezones (Dubai, Kolkata, Bangkok, Singapore, Shanghai, Tokyo, Seoul), and Pacific timezones (Sydney, Auckland).
All conversions account for daylight saving time (DST) automatically using the Internationalization API built into modern browsers. This ensures your conversions are accurate regardless of the season or local DST rules.
Frequently Asked Questions
Q Does this tool account for daylight saving time?
Yes! The converter uses the browser's built-in Internationalization API (Intl.DateTimeFormat) which automatically handles daylight saving time transitions for each timezone. The UTC offset shown reflects the actual offset at the specified date and time, including any DST adjustments.
Q What is UTC?
UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks and time. It's essentially the same as GMT (Greenwich Mean Time) for everyday purposes, but more precisely defined. All timezone offsets are expressed relative to UTC — for example, US/Eastern is UTC-5 (or UTC-4 during daylight saving time).
Q Why do some countries have half-hour offsets?
Not all timezones use whole-hour offsets from UTC. India uses UTC+5:30, Nepal uses UTC+5:45, and parts of Australia use UTC+9:30. These offsets were chosen based on geographical position and political decisions to align the clock time closer to solar time in those regions.
