How Fast Does Trello Calendar Sync To Google Calendar

Productivity Software

As a frequent user of both Trello and Google Calendar, I have often pondered the speed at which Trello’s calendar synchronizes with Google Calendar. In this article, I will delve into this matter, sharing my personal experience and offering detailed observations.


Trello, a popular project management tool, offers a seamless integration with Google Calendar. This integration allows you to view your Trello board’s due dates and deadlines directly in your Google Calendar. It’s a great feature that ensures you never miss an important deadline.

How Does the Trello Calendar Sync Work?

The Trello calendar sync operates using the iCalendar format, a standard for exchanging calendar information. When you enable the Trello-Google Calendar integration, Trello generates a unique iCalendar feed URL for your Trello board.

To sync your Trello board with Google Calendar, follow these steps:

  1. Open your Trello board and click on “Power-Ups” in the right-hand menu.
  2. Search for the Google Calendar power-up and click “Add” to enable it.
  3. Authorize Trello to access your Google Calendar account.
  4. Once authorized, you’ll see a new “Calendar” button on the right-hand menu of your Trello board.
  5. Click on the “Calendar” button to generate the iCalendar feed URL.
  6. Copy the URL provided.
  7. In your Google Calendar, click on the “+” button next to “Other calendars” and select “From URL”.
  8. Paste the copied iCalendar feed URL and click “Add calendar”.

Once you complete these steps, your Trello board’s due dates and deadlines will automatically sync to your Google Calendar. But how fast does this sync occur?

Sync Speed: My Personal Experience

Based on my personal experience, Trello’s calendar sync with Google Calendar is relatively fast. In most cases, I have noticed that updates made in Trello, such as adding or modifying due dates, are reflected in Google Calendar within a few minutes.

However, it’s important to note that the exact sync speed can vary based on several factors:

  • Trello Server Load: During times of high server load, such as when many users are actively making changes to their Trello boards, the sync speed may be slightly slower. This is because the Trello servers need to process a higher volume of data.
  • Google Calendar Sync Frequency: Google Calendar periodically syncs with external calendars. The frequency of these syncs can impact the speed at which changes from Trello are reflected in Google Calendar. While the exact sync frequency is not publicly disclosed by Google, it is generally considered to be within a few minutes.
  • Internet Connection: The speed of your internet connection can also affect the sync speed. A slower connection may result in a delay in updates being reflected in Google Calendar.

Overall, I have found Trello’s calendar sync with Google Calendar to be reliable and efficient, allowing me to seamlessly manage my tasks and deadlines across both platforms.


In conclusion, Trello’s calendar sync with Google Calendar is an invaluable feature for individuals and teams who rely on both platforms for task management. While the exact sync speed may vary based on factors such as server load and internet connection, in my personal experience, the sync is typically fast, with updates reflected in Google Calendar within a few minutes. By leveraging this integration, users can ensure they never miss an important deadline and stay on top of their tasks.
