Frequently Asked Questions
How accurate is this time zone converter?
Our converter uses official time zone data and updates in real-time. It automatically handles Daylight Saving Time changes for maximum accuracy.
Why is the time difference between Beijing and London sometimes 7 hours instead of 8?
London observes Daylight Saving Time (DST) from late March to late October, changing from GMT (UTC+0) to BST (UTC+1). During this period, the time difference with Beijing (UTC+8) is 7 hours instead of the standard 8 hours.
Does it handle Daylight Saving Time automatically?
Yes, the tool automatically adjusts for DST transitions in all supported locations. No manual adjustments needed - you'll see "(DST)" marked when daylight saving time is active.
Is this tool completely free?
Absolutely. No registration, no hidden fees, no usage limits. Use it as often as you need for personal or business purposes.
How many time zones can I compare at once?
You can add and compare unlimited time zones simultaneously. Perfect for managing global teams or international business.
What's the difference between GMT and UTC?
GMT (Greenwich Mean Time) and UTC (Coordinated Universal Time) are essentially the same. UTC is the modern international standard we use as reference.
Can I use this offline?
The tool requires internet connection to load and ensure up-to-date time zone data. Once loaded, basic functionality works offline using your device's system time.
Can I set a custom date and time for conversion?
Yes! Use the "Custom Date & Time" feature in the left panel to set any specific date and time. This is perfect for planning future meetings or checking historical time zones.
