I love the activity app on my iPhone home. Gives me a quick overview of my month. In fact just realized I missed my move goal yesterday so no chance for a perfect month. But that's fine. When I went back up to last month I notice I had nothing on a Friday Sept 5th. Which didn't make since. I knew I was driving that day so I would meet my goals but I should have got something. Even weirder, on the next day, Saturday, Sept6, I had data shown but I didn't wear my watch at all that day so It should be empty. After a few minutes I realized that the calendar days were wrong. The last listed day of the week was actually Sunday not Saturday. And the day I thought was Friday, was actually Saturday. So the day with no data was Saturday no Friday which is how it should have been. My iPhone calendar isn't set up like that so why is the activity app set up like that. And how to I fix the days of the week to be correct. I want Sunday to be the first day of the week like it should be. Does anyone know how to fix this?
