Have you ever been just slightly annoyed by the fact that one minute is 60 seconds and one hour is 60 minutes? Well, you can just stop using these two pseudo-units as they do not add any information. Simply just use the base unit of time (seconds) for time representation. To represent a large amounts of seconds use the standard SI prefixes like kilo (1 kilosecond = 1000 seconds).

This website is dedicated to provide you with all the information and tools you need to abandon the use of minutes and hours.

To support this cause simply stop using minutes and hours, and encourage your friends, family, co-workers, employer (or employees), etc. to do the same. If you meet somebody that still uses minutes and hours ask them the following: “Could you please explain me why you choose to represent time using base 60? Doesn’t it seem kind of illogical and inconsistent when you use the decimal system for all other purposes?”

Show your support by following this site on Twitter and liking it on Facebook. Please share and retweet so that your Facebook friends and Twitter followers will too know that they have a choice of abandoning minutes and hours.


So how to represent time using seconds only? Simply by not resetting the second counter every 60 seconds (and not adding one to the unnecessary minute counter). This way you have a simple and clear one-unit-only representation of time. This means that instead of having to represent one day as 24 hours of each 60 minutes of each 60 seconds you can simply represent one day as 86 400 seconds (86.4 kiloseconds). Any time during the day can therefore be represented as a number between 0 and 86.4 ks (kiloseconds). An example of this could be the time 60.21 ks which is equivalent to 16:43:30. In the apps section you will find apps that represents time this way.

However until everybody agrees to stop using minutes and hours you will need to be able to convert time between seconds and hours-minutes-seconds representation. One way would be to do the calculations and use 1 hour = 3600 s = 3.6 ks and 1 minute = 60 s = 0.06 ks. Another way would be to just start using the second-only representation and thereby get a natural intuition and feel for it. This could be done by remembering points during the day in both formats. You might find the figure below helpful to get you started.

As we can do perfectly fine with just the SI base unit for time and the SI prefixes, dropping the usage of minutes and hours seems like a logical choice. Listed below are some pros and cons of abandoning minutes and hours.




To help you ease the transition from minutes and hours to seconds only, this section introduce you to some helpful apps.

At the moment only two apps are listed, one for Mac OS X and a web app for smartphones. This will hopefully change soon. Have you developed an app for another platform that represents time as just seconds? Send a direct message on Twitter or Facebook and your app will soon be listed here too. The following apps would be nice to have: app/widget for Android, native iOS app, Windows Phone app, Windows (desktop) taskbar indicator, and apps for various Linux desktop environments. Simple code for time conversion can be found on the ArchWiki.

Mac app

This app simply adds a kilosecond clock to the menu bar of Mac OS X. The app is developed for (and tested at) Mac OS X 10.8 Mountain Lion but it might work for older versions as well.

You can customize the app by choosing unit prefix (kilo or none), decimal separator, and number of decimal places.

The app can not yet be downloaded from the Mac App Store and should therefore be downloaded directly from here:


To have the app start up automatically it should be added to your "login items" (System Preferences → Accounts → Login Items).

Please report back any problems and suggestions for improvement via Twitter or Facebook.

Web app

The web app is simply a webpage that shows you the time in seconds only. The development of this app is an ongoing process that hopefully will not end any time soon.

You can access the web app at:

If you have an iOS device you can add the app to your homescreen for easier access.


You have only yourself to blame if you miss an appointment.
