How to Add a Second Time Zone to Google Calendar

Adding a second time zone to Google Calendar shows two zones side by side along the left edge of the day and week views — perfect if you work with people in another region or travel often. You can also set a different time zone on individual events. This guide covers both the display setting and event-level time zones.

Display a secondary time zone (web)

The secondary time zone display is a web-only setting. It adds a second column of hour labels next to your primary one.

1. Open Google Calendar on a computer.
2. Click the gear icon → Settings.
3. In the left menu, under General, click Time zone.
4. Tick Display secondary time zone.
5. Choose the second zone from the dropdown.
6. Optionally give each zone a label (e.g., "NY" and "London") so the columns are easy to read.

Switch to Day or Week view to see both zones listed down the left side. There's also a Swap button here to flip which zone is primary — handy when you relocate.

You can display up to two time zones total (your primary plus one secondary). Google doesn't support a third.

Set the time zone for a single event

Sometimes one meeting belongs to a different zone than the rest of your calendar — for example a flight or a call hosted in another country.

1. Create or open an event and go to the full editor (More options).
2. Next to the time fields, click Time zone.
3. You'll see separate start and end time zone options. Pick the zone(s) for this event.
4. Save.

Setting a per-event zone keeps the meeting anchored to that zone even if you travel — Google adjusts the displayed local time automatically.

When to use each option

On mobile

The Google Calendar app doesn't show a secondary time zone column, but it does:

• Respect per-event time zones you set on the web.
• Let you change your primary time zone under Settings → General → Use device's time zone (turn it off to set a fixed zone).

For dual-zone viewing, use the web.

Tips

• Label your zones. Unlabeled columns of numbers are easy to misread — short labels like "PST"/"CET" prevent mistakes.
• Watch daylight saving. Zones shift on different dates; double-check cross-zone meetings around DST changes.
• Pair with working hours. If you collaborate across zones, set your working hours so others book you at sane local times.

If your schedule spans Google and Outlook across regions, nocal shows them together in one timeline so you read every event in the right context — see how.
