How to Combine Two Google Calendars Into One View

Combining two Google Calendars usually means seeing all their events together in one view — and Google does this natively by overlaying calendars rather than fusing them. If you truly need events from one calendar to live inside another, you'll import them. This guide covers both approaches and the limits of "merging" so you pick the right one.

First decide: overlay or merge?

These are different goals, and most people actually want the first.

Google Calendar has no single "Merge calendars" button. Overlaying is instant and reversible; importing copies events and is permanent.

Method 1: Overlay calendars (recommended)

If both calendars are already in your account or shared with you, you just need them visible at the same time.

1. Open Google Calendar.
2. In the left sidebar, look under My calendars and Other calendars.
3. Tick the checkbox next to each calendar you want to see.
4. All checked calendars now overlay in the same grid, each in its own color.

To add a calendar that isn't there yet (a coworker's, for example), they must share it with you, or you can subscribe to its iCal feed.

Give each calendar a distinct color so overlaid events stay readable — see how to change event colors.

Method 2: Merge events by importing

Use this only when you genuinely need events from one calendar to become events in another (for example, retiring an old calendar).

Step 1: Export the source calendar

1. Go to Settings (gear icon → Settings).
2. In the left menu click the calendar you want to copy from.
3. Open Import & export, or use Settings → Import & export.
4. Under Export, click Export. Google downloads a .zip containing one .ics file per calendar. Unzip it. See how to export your calendar to a file for details.

Step 2: Import into the target calendar

1. Still under Settings → Import & export, click Import.
2. Click Select file from your computer and choose the .ics for the source calendar.
3. Under Add to calendar, pick the destination calendar.
4. Click Import.

Events now appear in the target calendar as real, editable events.

The limits of merging

Importing copies events but isn't a perfect clone:

• It's one-time, not live. Future changes on the source calendar won't flow into the target. For an always-current copy, subscribe to the source's iCal feed instead.
• Recurring events generally import as a single recurring series, but unusual rules can flatten into individual events.
• You can't bulk-delete an import easily. If you change your mind, removing the imported events is tedious. Test with a small calendar first.
• No deduplication. Importing the same .ics twice creates duplicate events.

Which should you use?

• Just want one screen with everything? Overlay — it's free, instant, and reversible.
• Consolidating and deleting an old calendar? Import.
• Want a live mirror of someone else's calendar? Subscribe to its feed.

If you're trying to see Google and Outlook calendars in a single combined view, nocal merges them into one timeline without exporting anything — see how.
