Sharp World Clock is a feature-packed time zone clock and alarm clock software, using state of the art Microsoft programming technology (.Net / WPF) unlike most others.

Resizable Desktop World Clock / Time Zone Clock

Put Sharp World Clock on your Windows desktop as a constantly or temporarily visible timepiece, so you can see the time for every city or location you need. There is no limit for the number of clocks - it comes with a number of clocks, but you can easily add more. Clocks can be small or very big, in a window or single. Clocks are resizable without any loss of sharpness or visual quality, because the interface is using vector based graphics. You can have an analog or digital display of the time and date and any time format you like, in any language. » Download now

Alarm Clock: Alarms, Reminders, Chimes

Sharp World Clock features a powerful alarm center. It can be an alarm clock for you: always handy when you wish to add an appointment or reminder. You can add alarms for your current time zone or any other time zone, that you have set up a clock for. Just open the Alarm Center, select the date and the time and "Local Time" or "Time in City...". You can not only set up one-time (single) alarms, but also recurrent alarms (daily or annually) and countdown alarms. Alarms can be edited in the alarm list (for upcoming alarms) or in the alarm history list (for passed alarms). Chimes can be set on the hour and, optionally, on the quarter. You can use a realistically sounding bell sound (grandfather clock / church bell) or let the clock speak the time.

Desktop Calendar Widget

With the included calendar widget you always have a small month calendar widget on your desktop. It is steplessly resizable like the clocks and you can choose any color or background image you like, even make it semi-transparent. Clicking a day opens the alarm center dialog, ready to enter a new event. Events from the alarm center show up in the calendar as triangular markers and on mouse-over you can see the event details in a small popup window.

Time Zone Converter / Time Zone Calculator / Meeting Scheduler

Sharp World Clock comes with a time zone converter with three functions. 1. a converter, where you can select a city, time and date and get the time and date for another city you select. 2. a meeting planner, which shows you all cities you have in your current clocks and the time differences in a graphical overview. Move a slider to show the time for any given local time: easy to use for choosing the ideal time for phone conferences! 3. a time shift function - this moves the time and date in all your clocks within a -12..+12 hours time frame, showing the actual time in the selected locations.

Trust me....this desktop clock will remain a part of my desktop for a very long time!«
  • » Best clock program I have seen & worth for money spent. Nice interface & easy to customize; It has 34 preset faces to choose & almost everything is adjustable according to need. Time offset of other cities from local time is very useful. Graphical sky interface gives an easy visualization of other cities. Compared to other similar products its interface is attractive. Both analog and digital clocks can be set. There is no limit to the number of clocks. Time zone converter is provided. A graphic sky can be attached to the clock face - this is not seen in similar other products. Lots of other functions provided. I strongly recommend to try it.«
  • » I checked out quite a few sites, but this one stood out by far, because it's very good looking, highly customizable, powerful and trustworthy being 100% clean and tested. In short, nothing short of excellent. Finally, the author Mr. Johannes Wallroth is also very courteous, helpful and responsive.«
  • » Most of my customers are in other countries. I also have several sales people that are scattered over the USA. Sharp World Clock helps me keep up with time of both. I love it!.«
  • » Reliable, easy to use, lots of features. It is really one of the best in the market. You just have all in one: calculating time zone, multi-use alarm and every day remainder. Using it every day.«
  • » Great program with many as yet unexplored options - and I've been using it daily for over two years. With every new computer, Sharp World Clock is one of the first programs I install. Well worth the money, especially with free upgrades for life.«
  • » This is a feature rich and mature piece of software which I've been using for almost three years. I'm an engineer with appreciation for detail and this product provides a simple interface with layers of superb detail which allows me to configure precisely as I want. World Clock takes care of summer and winter savings time by applying the appropriate rules at the exact change over times - I dont need to concern myself with that detail. If you have a requirement for knowing local times around the world, this is the best software product available, I tried all I could find before settling on this and it's never let me down during the past three years..«
  • » I like it's many ways to customize it, the looks and the overall functionality, I have for an example 10 clocks on my desktop showing the time of my friends all over the world customized the way I want them. I have many DJ friends around the globe and I've always had the problem that I didn't know what their local time was. I tried many different so called world clocks but nothing as good as the Sharp World Clock. Very easy to configure and good looking app. Much recommended!«
  • » Features galore and they are just awesome. I am in the FOREX market, this clock makes my life considerably easier for the different time zones conversion I deal with. The support is speedy and very to the point. Thanks Mr Wallroth.«
  • » The Sharp World Clock takes care of my needs perfectly. I email or call people halfway around the world very often, so the night sky feature lets me know at a glance if I am calling too early or too late. Highly recommended even if you just call nationally from coast to coast. «
  • » I have been using this for many years, it is practical and colorful. Free updates forever and great customer service. Highly recommended. Just love the product.«
  • » I've used it for 4 years. Highly flexible and customizable, yet menus are easy to understand and use. So much people want every bell & whistle imaginable, which wouldn't necessarily make this better. Technical support is the BEST!«
  • » The product is top of the line for what it is intended to do. I have used other world clock programs but this one is tops in terms of look and feel, functionality and general usage. Just having it on my desktop gets people interested since so many people often need to know what time it is in other parts of the world. Conducting world-wise business, this at-a-glance look for world time is exactly what I have been looking for.«
  • » I travel a lot and have been using the Sharp World Clock for several years. It helps me avoid those calls when you have to say "Oh sorry, I forgot the 9 hour time difference..." Keep up the fine work - I don't know what I'd do without it. If you avoid a single embarrassing call that wakes someone in the middle of their night, it is money well spent. Stop looking for something free because you'll get exactly what you pay for. This is the BEST!«
  • » What has impressed me most about this product is the integration of both functionality and elegance, with no apparent "trade off" between the two. I've tried so many world clock programs and none have come close to this one. It's not just visually appealing either; the sound files (the chimes in particular) are hauntingly realistic. Highly recommended.«
  • » I can not imagine a feature you would want in a clock app that is not included in Sharp World Clock. It makes other clock programs look dumb. Version 5 has outdone itself. I like to trade on world markets like forex and I use this program to remind me when markets are opening or close. That is super easy with alarms and office hours. I can only think of about 100 other reasons to use it. If you need an app for even one other time zone I wouldn't bother with the others, I did and this is the one I was looking for. It is fun to configure and is really sharp.«
  • » My friends ask why I would pay for a clock program when there are so many that are free. Hah! There are mostly many that have very limited functionality. I congratulate you for your effort and your insights. This is by far the most useful of the many clock programs I've tried. The customizing options are superb. You've truly done a world-class job with it.

Version History
