I use PC at work with Lotus Notes 8.5 at home all of our life runs off Apple environment (2 iPhones, 2 iPads and 3 iMacs), I use an app at work called Mobile Iron which syncs up all my email, contacts and work calendar to my iPhone, I then use iCloud to sync with the rest of my devices (iPads and iMacs) I now have all my calendars sharing the same information regardless of the device I use to look it up on, if you don't have an iPhone or Mobile Iron is not the way to go for your company you can also sync up your lotus notes with a google calendar account and also sync that up with ical.
If you want add even more convenience, set up a google calendar account for the family and enter all the family events there like school schedules for your children, family gatherings, birthdays, etc. and sync that one up with your iphone as well, if you want to look only at your work schedule just tick the family calendar off or vice versa.
