Frequently Asked Questions
How does this tool handle Daylight Saving Time (DST) changes?
Our converter uses your browser's native ECMAScript Internationalization API (Intl.DateTimeFormat), which contains the up-to-date IANA Time Zone Database. All seasonal Daylight Saving Time shifts (such as EDT/EST and BST/GMT) are adjusted automatically with 100% precision.
What are the color-coded business hour indicators?
To make cross-border meeting scheduling effortless, each city displays a color status: Green (9:00 AM – 5:00 PM: Core Business Hours), Amber (7:00 AM – 9:00 AM and 5:00 PM – 9:00 PM: Extended Working/Available Hours), and Red (9:00 PM – 7:00 AM: Night/Off-Hours).
What is the difference between UTC and GMT?
UTC (Coordinated Universal Time) is the atomic time standard used globally for technical coordination. GMT (Greenwich Mean Time) is an actual geographical time zone used in parts of Europe and Africa. Functionally, both share the exact same +00:00 time offset without daylight saving adjustments.
Can I add my own custom cities and time zones?
Yes. You can use the 'Add Time Zone' dropdown to include any global city from the official IANA registry.
