Today, July 17 is a number that every Mac owner knows without exception. This number is used on the icon of one standard Mac OS X application — an elegant and simple
iCal calendar.
If you always wanted to know why July 17 was chosen as the date, now you will finally get an explanation. The thing is that it was on July 17 at the MacWorld Expo in New York that Apple introduced this very iCal. By the way, that exhibition was held in 2002, so iCal today celebrates its small anniversary.
Well, from me to you the translation of the comic (like the holiday itself) comic strip from the
team The Joy of Tech :

Yes, yes, today at the opening of iCal, the date July 17 won't go anywhere! Happy -holiday you, friends!
