Asana Calendar Not Syncing With Google Calendar? Here The Real Fix

Asana Calendar Not Syncing With Google Calendar? Here’s the Real Fix

A sync that shows nothing, outdated tasks, or refuses to update whenever you want it to isn’t usually a broken system – it’s either a setting, a feed URL issue, or an unexpected behavior of the sync process itself that someone didn’t think to explain.

(You know that afternoon I spent convinced my Asana → Google Calendar sync was broken before I finally gave up and stopped refreshing that feed URL? Half my troubleshooting time would’ve been saved if I’d known the one thing I eventually realized.)

Why This Happens

Before we get into solutions, let’s quickly cover the root causes:

  • The calendar feed URL was copied incorrectly or from the wrong project
  • The project/task visibility settings are private, excluding those tasks from the feed
  • The feed URL hasn’t refreshed yet (Google Calendar only pulls from it occasionally)
  • The wrong Google account is subscribed to the feed (common on shared/computer accounts)
  • Recurring tasks are duplicating/refreshing incorrectly
  • Timezone settings are different on Asana and Google Calendar, shifting when tasks appear without changing the date

The One Thing Most Guides Get Wrong

This is the detail most guides miss, and the reason half the problems described here don’t actually have solutions elsewhere: Asana’s calendar sync to Google Calendar only works through an ICS/iCal feed, and Google only pulls from that feed periodically. It isn’t a near-real-time or instant sync like most would expect.

In practice, this means Google Calendar will only refresh an external iCal feed somewhere between every few hours and once every 24 hours, at Google’s sole discretion. There is no setting inside Asana or Google Calendar that can make it update instantly. If a task was created, moved, or completed in Asana and it hasn’t shown up or stopped showing up in Google Calendar, in most cases, nothing is wrong – it’s just a matter of when Google decides to refresh the feed.

This single fact explains more “broken sync” issues than any other solution on this page, which is why it gets its own section.

How to Fix It

  1. Re-copy the feed URL to Google Calendar from Asana:

    In Asana, go to the project you want synced → click the calendar view → “Export to Calendar” → Copy the new feed URL and subscribe with Google Calendar instead of any old URL you might’ve used.

  2. Check task/project visibility:

    Private tasks and projects aren’t included in the feed at all, even if you have permission to view them normally.

  3. Confirm you’re subscribed with the correct Google account:

    If multiple Google accounts are logged into the same computer, you might be subscribed with the wrong one entirely.

  4. Try waiting before moving on:

    Give it at least several hours (ideally overnight) before deciding the sync is broken, as Google Calendar may just need more time to refresh the feed.

  5. Remove and re-add the subscription in Google Calendar:

    Delete the “Other calendars” entry for Asana → Re-add the feed URL subscription fresh, which may help it resynchronize properly.

  6. Check timezone settings in both apps:

    A discrepancy between Asana and Google Calendar’s time settings can cause tasks to appear hours earlier or later on one calendar than the other while still showing the same date.

Advanced Fixes

Try exporting a project-specific feed instead of “My Tasks”:
Project-specific feeds tend to be more consistent and predictable in their behavior, and they avoid including tasks from projects you don’t want on your calendar.

Rule out a browser/cache issue:
If tasks show up in Asana’s calendar but not Google Calendar, the issue is specifically with the export and subscription process, not Asana itself.

Check if recurring tasks are the specific problem:
Asana’s recurring tasks can show up in the iCal feed in unexpected ways depending on how far out they’re set to repeat, limiting the visible task window or duplicating unnecessarily.

Try “Refreshing calendars” in Google Calendar settings instead of just waiting:
Under Google Calendar Settings → “Other calendars,” there isn’t currently an option to manually refresh an external iCal feed, so the subscription removal/recreation method is your best alternative.

2026-Specific Sync Issues

  • Asana’s continued API and integration improvements through 2025-2026 have resulted in more teams using native Google Workspace integrations in place of the classic iCal feed method, potentially resulting in duplicate tasks showing up on the calendar from two separate sync processes
  • Google Workspace’s increased security and permission restrictions (rolled out throughout 2025 and 2026) mean a correctly formed feed URL can still fail silently on business/managed Google accounts due to an overarching organization-level restriction
  • Asana’s premium and enterprise plans increasingly separate calendar/portfolio sync capabilities from the free tier, resulting in some sync behaviors being noticeably different based on the specific plan instead of just the settings

A Faster Alternative Worth Knowing

If the periodic refresh behavior of the iCal feed is genuinely unacceptable, Asana also supports a faster, more direct calendar integration through Zapier or Make (formerly Integromat) that can push task changes to Google Calendar as events near-instantly, with the only caveat being the extra setup required compared to the native export.

About This Guide

I’ve set this up for myself and for small teams more times than I can count, and the single largest issue that always comes up is the refresh behavior not being intuitive or adjustable. Once I knew what was happening, troubleshooting actually had a meaningful impact instead of just spinning my wheels. I’ll continue to update this guide as both Asana and Google Workspace continue to change and refine their behaviors, as a working solution yesterday might require a minor adjustment today after one endpoint changed expectations for the other.

Frequently Asked Questions

Why does my Asana calendar sync show up as working but with outdated information?

This is almost certainly the expected behavior of Google Calendar’s external feed refresh system.

Can I make the sync occur in real time?

Not with the native iCal feed export, since Google controls when it refreshes and there’s no official way to force it to refresh immediately. For a true real-time or near-real-time sync, you’ll need to use a third-party automation tool like Zapier to push task changes directly to Google Calendar as events.

Why are some of my tasks not appearing on the synced calendar at all?

Private tasks and projects are excluded from the feed by design, even if you have permission to view them in Asana itself.

Does removing and re-adding the calendar subscription lose any data?

No – it only affects the subscription itself, not the data in Asana, since the feed only exports information, it doesn’t control or modify it.

Why do I keep getting duplicate events show up on my calendar?

This is most commonly caused by having both the classic iCal feed and a native Google Workspace integration set up simultaneously by accident; make sure there’s only one Asana calendar subscription in Google Calendar under “Other calendars.”
