Microsoft confirms its purchase of popular calendar app Sunrise

Last week, reports surfaced that Microsoft nabbed popular calendar app Sunrise. Today, the folks in Redmond confirmed the purchase. For the unfamiliar, Sunrise is a well-designed calendar for the web, Mac, iOS and Android that pulls info from iCal and Google Calendar. It also taps into Twitter, Facebook, TripIt, Evernote and more to make sure all of your commitments are accounted for. The app will continue to exist on its own and support those third-party add-ons, and Microsoft says it'll soon reveal how Sunrise's features will fit into its universal apps and services.

If you'll recall, Microsoft bought email startup Acompli back in December before making its mobile apps the iOS and Android versions of Outlook. Now, it seems the company is looking to make even more changes inside its email client -- one that's become a solid mobile option in the weeks following its release, packing both mail and calendar tools in the same place. Neither side is offering financial specifics, but those early rumblings hinted at a figure around $100 million.
