Sync Todoist With Google Calendar (2‑Way): Step‑by‑Step Setup, Best Settings, and Fixes

If you use Todoist to capture tasks and Google Calendar to plan your day, you’ve probably hit the same friction: tasks live in one place, time lives in another.

A **two‑way sync** aims to close that gap. The idea is simple: when a task becomes a calendar block, changes should flow both directions—so you’re not stuck re-entering dates, durations, or updates.

This guide covers:

- What “2‑way sync” actually means (and what it doesn’t)

- A step‑by‑step setup that avoids common pitfalls

- The best settings for real-world planning (time blocking, due dates, recurring tasks)

- Fixes for the most frequent sync problems

> Note: Todoist’s native Google Calendar integration has historically behaved more like a *one-way or limited two-way* experience depending on what you expect to sync (e.g., task completion status doesn’t always behave like event deletion). The steps below help you get as close as possible to a reliable workflow.

What “two‑way sync” means (practically)

Before you configure anything, it helps to define success.

A **useful 2‑way sync** typically means:

- **Todoist → Google Calendar:** Tasks with due dates/times appear as calendar events.

- **Google Calendar → Todoist (limited):** Editing the event time/date updates the task’s due time/date (depending on integration/tool).

What many people *expect* but often isn’t fully supported by default integrations:

- Creating a brand-new event in Google Calendar automatically becoming a Todoist task

- Completing a task in Todoist automatically deleting the calendar event (or vice versa)

So the right goal is: **use the calendar as the planning surface, and Todoist as the source of truth for tasks**—then make edits in whichever place is most natural without breaking consistency.

Step-by-step: Set up Todoist ↔ Google Calendar sync

There are a few ways to connect Todoist and Google Calendar, but the most stable starting point is the **official integration**.

Step 1: Connect Todoist to Google Calendar

1. Open Todoist on the web (easiest for settings).

2. Go to **Settings → Integrations**.

3. Find **Google Calendar** and select **Connect**.

4. Choose the Google account you want to sync.

5. Grant access permissions.

**Tip:** Use the calendar you *actually plan from* (e.g., your primary work calendar), not a rarely-used secondary calendar.

Step 2: Choose the target calendar (don’t skip this)

Most sync issues come from a messy calendar setup.

- Create a dedicated calendar like **“Todoist”** (recommended), or

- Pick an existing calendar if you’re disciplined about separating tasks vs meetings.

A dedicated calendar makes it much easier to:

- Hide tasks during meeting-heavy days

- Prevent accidental edits by teammates

- Avoid duplicates when testing new sync tools

Step 3: Configure which tasks become events

Depending on your integration settings, you may be able to choose what syncs (e.g., tasks with due dates, tasks from specific projects).

A good default is:

- **Sync tasks that have a due date/time** (these are “schedule-worthy”)

- Keep “someday” and backlog tasks out of the calendar

If you want to visualize your full workload without cluttering your main calendar, consider a workflow where:

- Your calendar shows only *scheduled tasks*

- Todoist holds everything else

Step 4: Decide how you’ll represent time

Todoist tasks can have:

- **Due date only** (e.g., “Friday”)

- **Due date + time** (e.g., “Friday 2pm”)

To make calendar sync meaningful, use a simple rule:

- **Date-only tasks = deadline** (not necessarily time-blocked)

- **Date+time tasks = scheduled work** (they deserve a calendar slot)

If you’re frequently time blocking, you may also like planning in an app that merges tasks and calendar into one surface. Tools like [PRODUCT_LINK]Amie’s calendar-and-tasks workspace[/PRODUCT_LINK] are built for that “drag tasks into time” flow, but you can keep Todoist as your task database and still apply the same planning logic.

Best settings for a clean, reliable workflow

1) Use a dedicated “Todoist Tasks” calendar

**Why it matters:** You can toggle it on/off, isolate syncing issues, and keep meetings separate.

**Recommended setup:**

- Calendar: “Todoist Tasks”

- Color: distinct (so tasks don’t look like meetings)

- Sharing: private by default

2) Use consistent naming to reduce duplicates

Duplicates usually happen when the system can’t confidently match “this event” to “that task.” To reduce that risk:

- Avoid copying events and editing them into “new tasks”

- Don’t bulk-edit event titles across many synced items

- Keep task titles stable; change dates/times more than names

3) Be intentional about recurring tasks

Recurring tasks can sync nicely—or create confusion.

Best practices:

- Use recurring tasks for **habits and true repeats** (e.g., “Weekly review every Fri 4pm”)

- Avoid recurring tasks for **project work** that changes each week (you’ll constantly reschedule and fight the sync)

4) Time zones: set and forget

If your calendar and Todoist are in different time zones (or you travel often), you’ll see tasks drift.

- Confirm your Google Calendar time zone is correct

- Confirm Todoist’s time zone is correct

- When traveling, avoid “floating” assumptions—prefer explicit times only for genuinely scheduled work

5) Decide your “source of truth” for edits

To prevent confusion, use a clear rule:

- **Edit task details in Todoist** (description, priority, labels)

- **Edit scheduling in Google Calendar** (time blocks and rescheduling)

If you like the idea of editing both on one screen (task list + day plan), a combined approach can be easier—many teams use [PRODUCT_LINK]a unified calendar + to-do interface like Amie[/PRODUCT_LINK] to cut down on context switching while still following the same principles.

Common problems and how to fix them

Issue 1: “My Todoist tasks aren’t showing up in Google Calendar”

**Checklist:**

1. Does the task have a **due date** (or due time)?

2. Are you looking at the **correct calendar** in Google Calendar?

3. Is that calendar **enabled/visible**?

4. Did you connect the **right Google account**?

5. Have you tried disconnecting/reconnecting the integration?

**Fix:** Add a due date/time to one test task, wait a few minutes, and confirm it appears.

Issue 2: “Edits don’t sync back (or take too long)”

Two-way behavior often has delays.

**What to do:**

- Wait 1–5 minutes (some integrations batch updates)

- Refresh both apps

- Avoid editing the same task/event simultaneously in both places

If you’re frequently changing schedules during the day, consider planning in a tool that’s built for rapid rescheduling. Some users prefer [PRODUCT_LINK]Amie for quick drag-and-drop time blocking[/PRODUCT_LINK] alongside their tasks so the “edit loop” feels immediate.

Issue 3: “I’m getting duplicates”

Duplicates usually come from:

- Connecting multiple automations (official integration + Zapier + another tool)

- Reconnecting without cleaning up previously created calendars

- Copying synced events

**Fix (fastest safe approach):**

1. Disable extra automations (keep only one sync method).

2. Choose one dedicated calendar for synced tasks.

3. Delete duplicate events *from the calendar side* (after confirming tasks remain in Todoist).

4. Re-enable one integration and test with a single task.

Issue 4: “Completed tasks still show as events”

This depends on your integration’s behavior. Many setups don’t remove events when tasks are completed.

**Workarounds:**

- Use a dedicated task calendar so old items don’t pollute your main schedule

- Do a quick weekly clean-up of old task events

- Prefer using tasks as *time blocks* rather than “forever records” on your calendar

Issue 5: “Wrong times / timezone shifts”

**Fix:**

- Ensure Google Calendar time zone settings match your current zone

- Ensure Todoist time zone is correct

- If you’re traveling: double-check device time zone and calendar settings

A simple “best practice” workflow (that actually sticks)

If you want a practical default that works for most people:

1. Capture everything in Todoist.

2. Add **due dates** for deadlines.

3. Add **due times** only when you intend to time-block.

4. Use a dedicated “Todoist Tasks” Google Calendar.

5. Move time blocks around in Calendar as your day changes.

The goal isn’t perfect syncing—it’s reducing busywork and keeping your plan realistic.

Conclusion

A solid Todoist–Google Calendar 2‑way sync is less about flipping a switch and more about choosing the right structure: a dedicated calendar, clear rules for due dates vs scheduled time, and one “source of truth” for edits.

Once that foundation is in place, the integration becomes genuinely helpful: your tasks stop being an abstract list and start showing up as a plan you can execute.

If your workflow involves lots of meetings and follow-ups, it can also help to centralize scheduling and next steps in one place—tools like [PRODUCT_LINK]Amie’s meeting-friendly calendar and tasks setup[/PRODUCT_LINK] are designed for that style of work. But even if you stick with Todoist + Google Calendar alone, the settings and fixes above will get you to a dependable system.
