I keep all my events in Backpack Calendar because I love the streamlined way to enter dates and times there. But now that I've got a spiffy new iPhone that can sync with iCal, I want my events to show up there too.
Well, good news: It's easy to share Backpack calendars in iCal format and then view them elsewhere (e.g. in an iCal that syncs with an iPhone). Here's how:
1. Go to your Backpack Calendar and click on the name of the specific calendar you want to share in the sidebar.
2. Then click the "Share this calendar" link that appears.
3. You'll see an iCal URL that can be pasted into another calendar program that accepts iCal feeds.
4. Copy that iCal URL and then go to the iCal app. Add a new calendar by clicking the "+" button at the bottom left of the app. Then right-click the calendar and select the "Subscribe" option.
5. Paste in the iCal URL you got from Backpack, hit the "Subscribe" button, and name your Calendar (you can choose how often to refresh it too). Your Backpack events will now show up in your iCal.
6. Now just sync your iCal with your iPhone. Voila, your Backpack calendar is mobile!
