Stop Calendar from changing time-zone I use Google Calendar instead of the stock calendar on my LG G5. I travel internationally on a weekly basis, and the Calendar app would automatically adjust the calendar events' scheduled time once I landed to a different time zone (if Auto Date &amp; Time is on) or once I adjusted the time zone manually (if Auto Date &amp; Time is off). 

The fact that Calendar Events' times got changed is utterly impractical and annoying.

For example, I would add an event at 8pm on a future date in that destination of a different time zone, and once I land there, the Calendar event time will be changed to 2pm. This throws off the timing of all my events. I almost missed several flights because the alarm did not go off at the right time, especially in connected flights crossing multiple time zones.

How can I stop Calendar from doing that? If I recall, iPhone does not do that.
It's a bit of inconvenience of how Google Calendar uses time zones.
Here is a brief explanation of how it uses time zones:

How Calendar uses time zones
When you create an event, you'll see it in your local time zone. It
will also show up in the local time zones for anyone you invite, even
if they're in a different time zone.

Some workarounds:
1. Disable device time zone
When you travel to a different time zone, you can see your calendar in the local time.

Open the Google Calendar app .
In the top left, tap Menu .
At the bottom, tap Settings .
Tap General.
Tap Use device time zone on or off.


If &quot;Use device time zone&quot; is on, your time zone will update
automatically as you travel. If &quot;Use device time zone is off&quot;, you can
select a time zone from the drop-down menu.

2. Create an event in a different time zone
There is another workaround involving setting time zone for an individual event in Google Calendar.
For example, if you're going on a trip to Bahamas and want to make sure your 2 PM island tour shows up on your calendar correctly, you should choose the time zone for Bahamas while creating your event. i.e

Create an event

Open the Calendar app .
Tap Create .
Tap Event .
Start typing in a title for your event. You'll often see suggestions – choose one or keep typing.
Tap Done .
Edit event details like the date, location, time, event visibility, and who's invited. If you don't share your calendar, you
won't see visibility settings at all for your event.
Optional: If you have more than one calendar and want to change which one you're adding the event to, go to the top and tap the
calendar name.
Tap Save.
