Frequently Asked Questions
How accurate is this time zone converter?
Our tool uses authoritative IANA time zone databases and updates in real-time. It handles Daylight Saving Time rules for regions like North America and Europe automatically.
Why is the time difference between NYC and London sometimes 5 hours and sometimes 4?
Because of Daylight Saving Time. When New York is on EDT (UTC-4) and London is on BST (UTC+1), the difference is 5 hours. When New York switches to EST (UTC-5) while London is still on BST, it can vary.
Does it handle Daylight Saving Time automatically?
Yes, the tool automatically adjusts for 'Spring Forward' and 'Fall Back' transitions for all supported locations. You'll see a 'DST' indicator when daylight saving is active.
Is this tool completely free?
Absolutely. No registration, no hidden fees, and no usage limits. Use it as much as you need for personal or business planning.
How many time zones can I compare at once?
You can add and compare unlimited time zones simultaneously. It is perfect for coordinating calls between San Francisco, New York, and London.
What's the difference between GMT and UTC?
GMT (Greenwich Mean Time) and UTC (Coordinated Universal Time) are essentially the same for most purposes. UTC is the scientific time standard used by the internet and aviation.
Can I use this offline?
The tool requires an internet connection to load the latest time zone data. Once loaded, basic functionality works offline using your device's system time settings.
Can I set a custom date and time for conversion?
Yes! Use the "Custom Date & Time" panel to schedule future events or check past times. Great for planning that conference call for next Tuesday at 2 PM.
