Why Calendar Time Zone Settings Matter

Your calendar time zone controls how events appear on your schedule. If it’s incorrect, events may show up at the wrong time—even if they were created correctly.

Common situations where time zone changes are needed:

Traveling to another country
Working with international teams
Online classes or virtual meetings
Recently moved to a new region
Events showing incorrect times
Daylight Saving Time changes

A properly set time zone keeps your schedule accurate and stress-free.

Understanding How Time Zones Work in Google Calendar

Google Calendar assigns a time zone to:

Your account
Each calendar
Individual events (if needed)

By default, Google Calendar uses the time zone from your device or Google Account. However, you can change it manually.

How to Check Your Current Calendar Time Zone

Before making changes, it’s a good idea to check what time zone your calendar is currently using.

Steps to Check Time Zone (Desktop)

Open Google Calendar
Click the gear icon (Settings)
Select Settings
Go to General → Time zone

Here, you’ll see:

Primary time zone
Option for secondary time zone

How to Change Calendar Time Zone on Desktop (PC or Laptop)

Add a Secondary Time Zone

A secondary time zone is helpful if you work with people in another country.

Tap the menu (☰)
Go to Settings
Tap General

💡 This gives you manual control instead of automatic syncing.

How to Change Time Zone for a Specific Calendar

If you manage multiple calendars, each one can have a different time zone.

This is useful for shared or work calendars.

How to Change Time Zone for Individual Events

Sometimes you only want to adjust a single event.

Why Events Show Wrong Times After Changing Time Zone

This is a common concern and totally normal.

Why It Happens

Events were created in a different time zone
Device and calendar time zones don’t match
Daylight Saving Time adjustments
Imported calendar conflicts

Changing the calendar time zone does not always change existing event times automatically.

How to Fix Events Showing Incorrect Times

Option 1: Edit Individual Events

Manually update event times and time zones.

Option 2: Use Event Time Zone Option

Enable time zone display in event settings.

Option 3: Recreate Important Events

For critical events, deleting and recreating ensures accuracy.

Time Zone and Daylight Saving Time (DST)

Google Calendar automatically adjusts for Daylight Saving Time—but only if your time zone is correct.

Common DST Issues

Events appear one hour early or late
Meetings shift unexpectedly
Recurring events change timing

Fix DST Problems

Confirm your calendar time zone
Avoid using “floating” times
Double-check recurring events

Best Practices for Managing Calendar Time Zones

Always confirm the time zone before scheduling meetings
Use secondary time zones for global work
Avoid frequent manual changes
Double-check imported calendars
Review calendar settings after travel

These habits prevent most scheduling problems.

Common Problems and Quick Solutions

Time Zone Keeps Changing Automatically?

→ Disable “Use device time zone.”

Events Shift After Travel?

→ Check calendar and device time zone sync

Shared Calendar Shows Wrong Time?

→ Askthe owner to confirm the calendar time zone

Imported Events Are Incorrect?

→ Adjust calendar-level time zone or recreate events

Difference Between Device Time Zone and Calendar Time Zone

Device time zone: Set by your phone or computer
Calendar time zone: Used by Google Calendar

If these don’t match, event times can look wrong.

Who Should Use Secondary Time Zones?

Secondary time zones are perfect for:

Remote workers
Freelancers
International teams
Students attending global classes
Business owners with overseas clients

It’s one of Google Calendar’s most underrated features.
