The 2.3.4 version of VistaClock for Mac is provided as a free download on our website. This software for Mac OS X was originally created by Mazookie, LLC. The program lies within Productivity Tools, more precisely Timekeeping.
From the developer:
VistaClock is a replacement for the Mac OSX build in menu bar clock. VistaClock not only gives you the time and optional week number icon display, but when you click on it, a dialog with calendar and analog clock opens up. Optionally you can add additional clocks with time zones.
You can quickly see the date for two weeks from next thursday. Or the day the 20th of next month falls on.
You may want to check out more Mac applications, such as InTouch With, TopAgenda or MyMenuDate, which might be similar to VistaClock.
