Well today is the one day of the year that iCal shows the correct date without the program being opened. It marks first time iCal was announced to the public (ie birthed) back on July 17th, 2002.
This day is also significant because my brother was born on this day.

BTW: I should note that the Calendar feature on the iPhone displays the current date in the logo, while the weather widget constantly displays 73 degrees and sunny. Also, the Joy of Tech points out that we can now celebrate iPhone clock hour twice a day:
