What Is WorldTimeBuddy and What Can It Do?

Updated

WorldTimeBuddy (worldtimebuddy.com) is a free online world clock, time zone converter, and meeting scheduler. It is built for anyone who needs to compare several time zones at once — people scheduling conference calls, webinars, or international phone calls, as well as travelers and anyone tracking market hours across regions. You can use it in a browser without signing in; signing in is only needed if you want to save your settings.

What the tool actually does

The site combines three functions that are usually split across separate apps:

  • World clock — shows the current time in multiple cities side by side.
  • Time zone converter — lets you compare hours across those cities at a glance.
  • Meeting scheduler — turns a chosen hour into a shareable event.

The core idea is comparison "at a glance": instead of converting one time at a time, you see all your locations lined up on the same horizontal scale.

How to use it

The site's own getting-started steps are short:

  1. Add locations — add, remove, set a home city, or reorder the cities you care about.
  2. Mouse over hours — hover over an hour to convert time at a glance.
  3. Click hour tiles — click an hour to schedule and share it.

A practical example: you are in New York and need a call with someone in Buenos Aires and someone in London. Add all three cities, hover along the row until the working hours overlap, then click that hour tile to build the event.

Features worth knowing

  • Multiple time zones in one view — the main advantage over single-conversion tools.
  • Widgets — a World Clock Widget and an Event Widget.
  • Mobile app — available alongside the web version.
  • Calendar and sharing options — the interface references Outlook / iCal, Google Calendar, Clipboard, Gmail, and a link to the selection, so a chosen time can be exported or shared.
  • Display settings — options include showing time zones, marking weekends, and calendars, plus am/pm vs 24-hour format.
  • Sign in to save settings — the site states this is free.

Who it is for

Use case How WorldTimeBuddy helps
Scheduling conference calls, webinars, online meetings Compare all attendees' time zones and pick an hour that works
International phone calls to friends or family Quickly see whether it is a reasonable hour abroad
Business travel and flights Check arrival times and local times across zones

Things to keep in mind

  • The page requires JavaScript enabled to work properly.
  • Signing in is optional and only relevant if you want your settings saved; the site describes this as free.
  • The tool is a converter and planner — it does not place the call or book the meeting for you. You still export or share the selected time through your own calendar or messaging tool.

If your main problem is "what time is it there, and when can we all meet?", WorldTimeBuddy is designed to answer both in one screen.
