The MVPS Calendar is hosted on Google Calendars. You can access it via this link.
You can even subscribe to this calendar and have it appear right on your own Google Calendar. Just click the “Google Calendar” button 
in the lower right corner of the Google calendar below, on this page. Note that you must have a free Google account to subscribe, you can create one with this link if you need to.
Once you are subscribed to a Google Calendar, you can get it to synchronize with your desktop calendaring application and smart phone calendar, too! Use this link to do that.
For more information on synchronizing Google calendars, read this Google Support document for help.
