I just added DateLine to my regular apps. From developer MachineCodex’s website:
DateLine is a small, simple app which displays a linear calendar on your desktop in a transparent window. It provides easy access to iCal by double clicking on a day. The background and text colors are customizable with support for transparency.
For me, it solves the problem of needing the date readily handy but not having much MenuBar real estate on my 13″ MacBook. I put DateLine on my desktop, and when I need it I invoke Expose Show Desktop.
