Making Calendar Event End Before It Begins

I haven't seen how to do that but I think M. C. Escher drew it once.

 

Can you elaborate on what you want to accomplish?

 

You'd hope that any respectable calendar app developer would deliberately prevent events finishing before they'd started, since its impossible in the real world. Unless of course you've invented time travel! As Mr_Brightside_@ says, if you can explain what you're trying to achieve then it might be easier to point you in the right direction.

 

I certainly hope that this is not possible as it would probably make a lot of applications crash.

 

Event start and end times are both tied to the same time zone. In your case the flight only ends "before" it starts when you use different time zones for start and end. Simply insert both times with your departing time zone and your phone will display you the correct event times in your destination time zone when you land.

 

That's pretty funny, but if you're Mac is aware of what time zone(s) you're in for the duration of the meeting then the calendar will make all the shifts...and it won't matter where you are...the meeting will show as ending after it begins.

On the plane you'll have to change time zones manually, I'm sure: System Preferences>Date & Time>Time Zone. Have the pilot keep you updated. I'm sure he or she will be more than happy to oblige you.

 

Bottom line is that there isn't a "problem" here.
