Best Free Multiple Timezone World Clock



If you're like me and have friends and family in other countries, or need to work on a daily basis with people in multiple timezones around the world, then this page is for you. I have searched, and found a vast number of web sites claiming to have free multiple timezone world clock utilities, able to display multiple times and clocks simultaneously.

Unfortunately, many web sites have misleading keywords and text around the applications, apparently all they want is page hits and will shamelessly attract people with deception. A large percentage of the pages I have visited in my searches for a good utility yielded almost entirely fully commercial or shareware applications. I prefer to use true freeware, which is the purpose of this website, and in fact this software category.

Many of the utilities are also very limited, not delivering on what the pages promise, or being limited in the number of clocks that can be displayed simultaneously. For some people, the magic number of five simultaneous clocks offered by many programs might be enough. For anyone working for a global company, dealing with people in different time zones on a daily basis, you will probably find, like me, that five just doesn't cut it, and you need more like ten or even twenty different times available.

NTP Time Zone Clock  

A no-frills clock with all configured times displayed in a single, simple window

Our Rating: 
License: Free
Very small and easy to use, font size changes automatically as you resize the window, NTP time server setting, a fairly comprehensive list of countries and cities is available for selection, and adding a new city is easy, times are displayed in the task bar icon even when the main window is minimized.
Times are always displayed in 24 hour format, no option exists for 12 or 24, and no option exists to turn off display of seconds, transparent mode is rather ugly, not true transparent mode, it simply removes the background color.

Sun Clock  

A world clock that's cool to look at with its graphical map of the earth

Our Rating: 
License: Free (Limited features)
Cool, easy to configure and use, many cities already configured into the system and the world map can be centered on your own home city.
Rather a big download, memory hungry, can't display just a small window with times, can't stay running when switching to other windows, a little slow, no mouse cursor ever shows and you have to just figure out to right click on the display.

Web-based World Clocks and Browser Add-ons

There are many online time services and you may find an online clock or a browser addon is all you need and has the added advantage that you don't have to install yet another new application on your computer. is the one I have found most versatile than any other sites available. It allows you to see the time and date of virtually any city in every country. If you want to customize it and create your own settings for a custom clock with all the time zones you care about, you can create a free account to store your settings so that your custom clock display is always displayed just the way you want it. So far I have not seen any spam associated with the email address I used to register on the web site, so I believe I can recommend it with no hesitation.

The real benefit of a web based service like this over browser based addons is that it is truly portable, in that it is available no matter whether you use your own computer or another, and no matter what web browser is available to you.


FoxClocks is a very versatile and fully featured multi timezone clock addon to Firefox browser. It works just the same way in both Firefox and Thunderbird. It is very configurable, allowing just about any number of clocks and can be configured to display in the status bar (left or right) or in a toolbar.

A really nice feature is the ability to display a little flag icon next to the time for a quick and easy visual identification, and also the ability to change the color of the text used to display the clock depending on the time. I use this to have my primary remote timezone display green during waking hours, and red during the night. Another nice feature is the ability to pick a few clocks to display in the status bar (or toolbar), and have all your configured clocks display when you hover your mouse over the FoxClocks in your status bar. The timezone database is kept up to date, an important feature when countries change their daylight savings time rules.

I installed Qlock, and was keen to use the World Map.
I cannot see it in the right click of SysTray menu ?
Possibly it is a pro feature ?, but the web page says the option should still be there, and be marked Pro.
But I see no mention of it (free or Pro)

PS I tried WorldClock. It installed without any fuss, but it would not show anything, when I right clicked it's SysTray menu option 'Show'

How about DSClock? Free. I've been using it for years.

Updated: Qlock is now the editors' choice in this category as the previous toppick WordClock didn't work well in Windows 10 when tested.

Advanced World Clock does look great, I'm a little nervous that the download link on the site actually downloads a downloader but I'll give it a whirl in vbox later anyway, as it looks v good.

I'd like to add a couple too - for a very simple systray tooltip to which you can add your own timezones, go to the MooO software site and find "World Time". For something with more eye-candy and fun to play with, try "World Clock" from, there's a portable version on the PAF website.

Of course the W7 clock also lets you add custom timezones as well which is pretty neat.

I have removed the URL reference for this one because there is enough doubt as to its safety. Normally, one or even two instances on VT might be false positives but when several sites flag the same source, caution is advised. MC - Site Manager.

When you run it, the Advanced World Clock installer does not appear in a list of programs to kill, instead it opens another installer inside it which has a different name so it isn't easy to figure out what to look for when killing it. The install package itself then wants to install a toolbar and change your home page and it is rather insistent about it.

No idea what the clock itself is like because I terminated the install at that point.
