MagiCal is a free menu-based clock and calendar for your Mac OS X Menu Bar. It features a huge range of configuration options for how the time and date are displayed, and can operate in conjunction with, or as a replacement for built in system menu clock.
In addition to this, MagiCal features a handy drop-down calendar that can be torn off and placed anywhere on screen.
MagiCal is available in three versions: PPC-only, Intel-only or Universal.

MacDailyNews Note: Intel-only version tested. It works well. Recommended. Note also that you can type directly into the application’s Date and Time preferences to achieve exactly the look and format you desire.
