Calendar was one of the original apps on the original iPhone. It started off simply but over the years it added Exchange support, landscape mode, a week view, a year view on iPad, the ability to touch and drag events around, and more. Apple renamed iCal on the Mac to Calendar to match the iPhone and iPad. And, after an era of heavy design, Calendar also got a clean, crisp makeover as part of the overall iOS redesign last year.
