Our website provided a free download of PandoCalendar 7.0.8 for Mac. The application belongs to Productivity Tools. This free Mac app is a product of Panda Systems.
From the developer:
This useful Mac-only program places a fully functional calendar on your desktop.
The look is completely customizable. You can change the calendar's font, size, and the colors used to draw the calendar; the background can be entirely transparent, so you can still see your desktop picture; you can center the current week (so you are always able to look back and ahead a full month at a time).
You may want to check out more Mac applications, such as VoodooPad 5, PersonalBrain or Thoughts, which might be similar to PandoCalendar.
