Frequently Asked Questions
Why does the converted time sometimes show the previous day or +1 day?
Time zones are offset from one another by several hours. When the difference crosses midnight, the converted result may land on the previous calendar day or the next day.
Does this time zone converter account for daylight saving time?
Yes. The converter uses the browser's built-in internationalization data, which applies daylight saving time rules for supported regions when relevant dates are selected.
What is UTC and why is it important?
UTC stands for Coordinated Universal Time. It is the global time standard used to compare local times around the world and avoid confusion between regional offsets.
Can I compare more than two time zones at once?
Yes. Use the Add timezone button to add extra comparison rows so you can line up several cities or regions side by side.
Why might a city have a different UTC offset during the year?
Many regions switch between standard time and daylight saving time. That changes the UTC offset during certain months, which is why the selected date matters.
