Do you like your calendar to start on Monday so that you see the entire week, followed by the weekend on a single line? Do you have an unusual job and want to start your calendar on a Thursday and have Wednesday be the last day of the week? Customizing iOS for this is easy:
- Mail, Contacts, & Calendars
- Scroll down to the bottom and tap "Start Week On"
- Select your desired day
- Tap the go back button in the top left (in blue)
This tip works on all iOS devices and versions of iOS.
