The Pack 26 Google Calendar is iCal compliant and can be synced with many types of calendar software including Apple's iCal, Google Calendar, Mozilla Calendar, Sunbird, Windows Calendar and Yahoo! Calendar Beta. Simply open your calendar program and subscribe to our ical feed:http://www.google.com/calendar/ical/hop.pack.26%40gmail.com/public/basic.ics And if you have your calendar software automatically sync to your Smartphone, then you should be able to access the pack calendar from your Smartphone too. If a Pack 26 event changes during the year, your own calendar will be automatically updated, just like with the HPS Source Book Calendar.
