How to Use the Timezone Converter
Three simple steps to track any timezone and find times that work for everyone.
Add Countries
Click "Add Country or Timezone" and search for any country or region. Your own timezone is always pinned at the top.
Watch the Live Clocks
Each row shows live local time, UTC offset, and how many hours ahead or behind you it is. The day/night gradient bar updates in real time.
Drag to Explore
Drag the day/night bar on any row to scrub through time — all rows sync together instantly so you can see what time it is everywhere at once.
Frequently Asked Questions
Does the timezone converter work offline?
Yes. All timezone conversions happen entirely in your browser using the built-in Intl API — no network requests needed. Once the page loads, you can use it offline.
Are the times automatically updated for daylight saving?
Yes. The tool uses the IANA timezone database built into your browser, which handles daylight saving transitions automatically for every country and region.
Will my saved timezones be remembered next time?
Yes. Your country list is saved to your browser's local storage and restored automatically on your next visit. No account needed.
How do I compare times across timezones?
Add your countries using the "Add Country or Timezone" button. Then drag the day/night bar on any row — all rows sync together so you can instantly see the corresponding local time everywhere.
Can I add countries with multiple timezones like the US or Russia?
Yes. When you search for a country with multiple timezones, every timezone option is listed — so you can add Eastern, Central, Mountain, and Pacific separately.
