I don’t know about you, but I’m constantly forgetting when our US Holidays occur. I work from home so I schedule my days off whenever I need them, (well, honestly every day is a day off if I’m not working on a freelance project), but I’d like to know in advance when the my friends and family are going to have some holiday time to hang out. So, I looked on Apple’s site and I found a US Holiday Calendar for iCal. Stoked. I highly recommend this calendar if you forget when US Holidays are.
