How the Time Zone Converter Works
Our time zone converter uses JavaScript's Date object and time zone offset calculations to convert time between different time zones accurately. The conversion process includes:
- Time Zone Offset Calculation: Each time zone has an offset from UTC (Coordinated Universal Time). The calculator uses these offsets to determine the time difference between zones.
- Daylight Saving Time Handling: The calculator automatically accounts for daylight saving time (DST) based on the date you're converting. DST rules vary by region and are applied correctly.
- Date Line Crossing: When time zone conversion crosses the International Date Line, the date changes. Our calculator correctly handles this, showing both the converted time and correct date.
- Precision: Conversions are accurate down to the minute, accounting for half-hour and quarter-hour time zone offsets where applicable.
The calculator supports major time zones worldwide and handles all standard time zone variations, including those with fractional hour offsets. All conversions use UTC as the reference point for maximum accuracy.

Tips & Best Practices
Daylight saving time can change time zone offsets. Our calculator handles this automatically, but when planning far in advance, verify DST dates for your target time zones to ensure accuracy.
When dealing with international time, 24-hour format (military time) eliminates AM/PM confusion and reduces errors in time zone conversion, especially for early morning or late evening times.
Time zone conversion can change the date. For example, 2 AM on Monday in one time zone might be 11 PM on Sunday in another. Always verify both date and time in your conversion.
For important events like flights, meetings, or deadlines, double-check your time zone conversion. Even small errors can cause significant problems, especially for time-sensitive activities.
