My calendar has been showing that It's one day ahead. For example today it the 17th of April, my calendar has the RED circle on the 18th. Anyone know what to do to fix it? It's been doing that for the past couple of months. I've restarted my computer and checked the time/date settings on the computer multiple times but keeps doing it. This is only happening on my laptop and not on my iPhone or iPad.
MacBook Pro, iOS 10.3.1, Version 10.11.6
I had the same issue and finally figured it out tonight. I went to Calendar preferences > Advanced > and unchecked "Turn on time zone support". The day reverted back to the correct day. I check the box again and it remained the same day. Hope this helps you as well!

If the wrong date or time is displayed in some apps on your MacDate and time formats are user account-specific, so one user account might see the correct date modified on a file, while another user on the same might see an incorrect date modified on the same file.
To determine if you are seeing incorrect dates or times because of a custom date or time format use these steps:
OS X Yosemite and Mavericks
- Open System Preferences.
- From the View menu, choose Language & Region.
- Click the Advanced button.
- Click the Dates tab.
- Click the Restore Defaults button.
- Click the Times tab.
- Click the Restore Defaults button.
- Click OK.
- Quit the app where you were seeing incorrect dates or times displayed.
- Open the app again, and verify that the dates and times are now displayed correctly.
That did NOT help. My date and time was already on default setting. I went ahead and changed and changed back again to default settings then restarted the Calendar app but nothing changed. The funny thing is right now the apps bar shows the calendar to be 18 April (correct date) but the calendar itself still shows 19 April encircled (still one day ahead).
Click on finder > Go > Computer > MacintoshHD > Preferences > drag and drop com.apple.timezone.auto.plist to the desktop and restart the machine , see if it works .Otherwise just wipe out the hard drive completely and once again install the operating system .
Calendar marking that it's one day ahead!
