Managing multiple calendars can be a pain, especially if you have a busy schedule. It can be difficult to keep track of all your appointments and events, and it's easy to forget something important. But what if there was a way to aggregate all your calendars into one place?
In this article, we'll show you how to aggregate multiple calendars into one, using a variety of different methods. We'll also discuss the benefits of aggregating your calendars, and why it's such a great way to improve your time management skills.
What is the best way to aggregate multiple calendars into one
OneCal is the simplest and most reliable way to combine multiple calendars into one. It can aggregate multiple Outlook and Google Calendars in under a minute, and the calendars stay in sync in real-time. This means that any new meetings or events you create in one calendar will be automatically updated in your target calendar.
How to automatically aggregate multiple Outlook and Google Calendars into one using OneCal
- Connect your Calendars. The first step is to connect all the calendars you want to aggregate. You can connect multiple Google Calendars or Outlook Calendars.
- Choose one-way as sync direction. With OneCal, you can aggregate one calendar into another or multiple calendars at the same time. To aggregate multiple calendars into one, choose one way.
- Choose the source calendar and the calendar you want to aggregate it to. The third step is to choose which calendar are you going to aggregate, and the target calendar you’ll aggregate it to.
- Configure how events are reflected across your calendars. To protect your privacy when aggregating multiple calendars into one, it is important to be selective about which information you share. One option is to only sync a generic placeholder title, such as "Busy." This will ensure that you reserve the time as busy in all your work calendars, without disclosing any confidential information.
Your calendars are aggregated into one!
The selected source calendar is aggregated into the target calendar. OneCal will keep the aggregation updated in real time.
To aggregate more calendars into the target calendar, please follow the same process again.
For example, if you want to aggregate 4 calendars (A, B, C, D) into one (calendar E), you have to follow these steps:
- Create a sync with source A and target calendar E
- Create a sync with source B and target calendar E
- Create a sync with source C and target calendar E
- Create a sync with source D and target calendar E

How to Manually Aggregate Multiple Calendars Into One
Calendar sharing is another way to aggregate multiple calendars into one. The downfall of this method is that you’ll have to repeat a long process process for each calendar (usually 13 steps to aggregate one calendar to another). Let's say you want to aggregate 4 calendars into one. Let’s name the calendars A, B, C, D, and Target. The process would be:
- Export calendar A, and import it into the Target Calendar
- Export calendar B, and import it into the Target Calendar
- Export calendar C, and import it into the Target Calendar
- Export calendar D, and import it into the Target Calendar
The biggest downfall is that updates don’t happen in real-time. If a meeting is created into calendar A, you’ll have to wait up to 24 hours for the meeting to be reflected in the Target calendar.
Furthermore, if team members want to meet with you on the aggregated calendar, they won't be able to see any of the meetings from the calendars you just aggregated, as providers only check for busy slots on primary calendars, not imported calendars.
Let’s break down how to auto-block time across two calendars, by provider:
Aggregate an Outlook Calendar with a Google Calendar

Drawbacks of Manually Aggregating Multiple Calendars Into One
- Meeting conflicts: If your team uses the "Find a Time" feature in your target calendars to schedule meetings, they will only be able to see events in your primary calendar. This can lead to scheduling conflicts that span across multiple calendars.
- Privacy concerns: Aggregating multiple calendars into one via sharing offers limited privacy controls. You will need to decide whether to make all events public or private. This may be a concern for workspace administrators, who could potentially access event information and details from the imported calendars.
- Unreliable aggregation: When aggregating from a Google Calendar to an Outlook Calendar through sharing, it can take 24 hours or more for new changes to be reflected. Often, these changes do not synchronize correctly, which can increase the risk of double bookings and cause confusion among team members.
- Complicated setup: You can only aggregate one calendar to another. Since syncing is done through sharing, this means that if you have multiple calendars, you will need to repeat the same process for each pair. This can be redundant and time-consuming.
