About Time Zone Converter
This time zone converter lets you instantly convert a date and time from one world time zone to another. It uses the built-in Intl.DateTimeFormat API to accurately handle daylight saving time (DST) transitions and UTC offsets. Simply select the source and destination time zones, enter the date and time you want to convert, and click Convert. You can also use the Swap button to quickly reverse the direction of conversion. The tool covers 27 major cities across all continents, from Honolulu to Auckland.
FAQ
- How does the time zone converter handle daylight saving time?
- The converter uses the JavaScript Intl.DateTimeFormat API, which automatically accounts for daylight saving time (DST) rules for each time zone. This means the result correctly reflects whether DST is in effect on the selected date.
- What is the difference between UTC and GMT?
- UTC (Coordinated Universal Time) and GMT (Greenwich Mean Time) are essentially the same at offset +00:00. However, GMT is a time zone used primarily in the UK (and switches to BST in summer), while UTC is the universal time standard used as the reference point for all time zones worldwide.
- Why does the time difference show half-hours or quarter-hours?
- Not all time zones are offset by whole hours. For example, India Standard Time (IST) is UTC+5:30, Nepal is UTC+5:45, and several Australian zones use half-hour offsets. The converter correctly displays these fractional offsets.
