iCalendar on MacBook Air is one day off - iPhone is showing correct dates
My main contact list is on OneDrive and I am using this list for my contacts on both MacBook and iPhone. (iCloud is deactivated).
When looking at birthdays on MacBook, they are indicated +1 day.
On iPhone and OneDrive Contact-list dates are correct.
Timezones on all 3 are Belgium / Brussels. How can I fix this?
Thank you for your feedback
MacBook Pro 13″, OS X 10.10
