Frequently Asked Questions
How does the time zone converter work?
Our converter uses your browser's built-in Intl timezone database (the same standard used by every major operating system) to calculate accurate times across 500+ cities. It automatically accounts for daylight saving time transitions so you always see the correct local time.
Does this tool account for daylight saving time?
Yes. Because we rely on real-time IANA timezone data provided by your browser, every conversion reflects the current DST status of both cities. When clocks spring forward or fall back, the converter adjusts automatically.
What is the best time to make international calls?
The green overlap zone on the timeline shows hours that fall within business hours (9 AM – 5 PM) in both cities. This is generally the most convenient window for international calls. The tool highlights this range automatically when you select two cities.
Can I share a time zone conversion with someone?
Absolutely. Use the Link button to copy a shareable URL, the Text button for a plain-text summary you can paste into a message, or the Image button to generate a visual card you can share on social media or in chat.
How many cities does this converter support?
The converter includes over 500 cities covering every IANA timezone in the world. This includes all US cities with populations over 200,000, every world capital, and major metros across India, the Philippines, Europe, Latin America, the Middle East, and more.
