Free Time Zone Converter - World Clock

Convert times between world time zones instantly. Features live world clocks with pinning for premium users.

What Is Time Zone Converter?

A time zone converter translates a specific time from one time zone to another. There are over 24 standard time zones globally (some use half-hour or quarter-hour offsets), and many observe daylight saving time which shifts their offset seasonally. Converting between time zones manually — especially accounting for DST — is error-prone.

This tool converts a time between any two world time zones, handles daylight saving transitions automatically, and shows a World Clocks panel with several zones' current time simultaneously. This is essential for scheduling international calls, catching live events broadcast in other regions and coordinating with remote team members.

Free users see 10 time zones. Premium unlocks all 20, lets you pin your favourite zones to the top of World Clocks, and adds a Meeting Planner — a colour-coded grid showing what hour it is in each of your chosen zones across the day, so you can spot working-hours overlap at a glance.

How to Use This Tool

  1. Select the source time zone and enter the time you want to convert.
  2. Select the target time zone.
  3. View the converted time, with a day-difference note if it lands on a different date.
  4. Check the World Clocks panel below for several zones' current time at once.
  5. Premium: pin your most-used zones to the top of World Clocks, or use the Meeting Planner to find overlapping working hours across multiple zones.

Tips & Best Practices

  • UTC (Coordinated Universal Time) never observes DST — use it as a reference point to avoid confusion.
  • The US has 6 time zones (Eastern to Hawaii); the EU has 3 (Western, Central, Eastern); China uses a single time zone despite spanning 5.
  • DST transitions happen on different dates in different countries — the US and EU change on different weekends.
  • India is UTC+5:30 and Nepal is UTC+5:45 — not all offsets are whole hours.

Common Use Cases

  • Scheduling international calls and video conferences.
  • Finding out what time a live event will air in your time zone.
  • Coordinating across remote teams working in different regions.
  • Planning travel and adjusting to new time zones.
