I find a error in iPhone calendar
Year 1900 is not a leap year. In iPhone calendar, there are 29 days in 1900 and there are 8 days in that week. If you can fix it, it will be good
iPhone 5, iOS 7.0.6
I looked at my calendar and I see the same thing. I don't see any need for a fix unless it is for historical purposes as I don't plan on using that year for any information. You can offer feedback to Apple here: http://www.apple.com/feedback/
