What is the problem with having two calendars?
Meetings are in Google Calendar because that’s where you arrange them with clients and receive invitations. Task due dates are in Task Manager. To plan your day, you check both places. If you check only one, it’s easy to miss a date in the other.
Task Manager connects to Google Calendar in both directions. Events from Google appear in the Task Manager Calendar, and changes made in Google come through every few minutes. When you move an event like this in Task Manager, or change its time or details, the app first tries to save the change in Google. If that doesn’t work, the event won’t change in either calendar. When you enable “Add new events from Task Manager to this calendar”, new events can also be sent to Google - to one selected connection.
The connection is personal: only you can see events from your Google account. You can connect several accounts at once, such as your work and personal accounts. You choose a calendar for each one; the connections work independently.
How do you connect an account, and what happens next?
An administrator creates OAuth credentials (Client ID and Client Secret) in Google Cloud, then pastes them into Settings, under Advanced → Google Calendar (OAuth). You can also connect your account using your own credentials in Settings → Profile → Google Calendar, without involving an administrator. After that, each team member goes to Settings → Profile → Google Calendar. They click “Connect Google account”, choose an account, grant access and select a calendar to import. They can connect another account in the same section.
By default, the import covers the period from 30 days ago to one year ahead. You can change this window for each connection. Events keep the colour assigned to them in Google, or the calendar colour if they don’t have one. Google expands recurring events into individual occurrences during import; Task Manager doesn’t store the recurrence rule. When you open an event, you’ll see the label “Google event” and a link to open it on the other side.
You can drag an event like this to another date, change its duration or details, or delete it. The change will be sent to Google. If you have Google Calendar connected and don’t want to wait for background sync, the circular two-arrow icon in the Calendar toolbar will fetch changes straight away. You’ll see how many events were added, changed and removed. If background sync fails, the icon turns orange and shows the reason when you hover over it.
What do you gain?
You don’t have to plan your day using two separate views. You can see a proposal deadline next to a client meeting, so you can plan your work around both commitments.
You don’t have to copy arrangements between calendars. Enter an event once, wherever you happen to be, instead of remembering to move it manually.
When you plan your day using only work commitments, it’s easy to miss a personal doctor’s appointment. You can see it alongside work meetings, while your team can’t see events from your Google account.
Use case: a sales representative with two accounts
Marta arranges client meetings in her work Google Calendar. She keeps her child’s pick-up and doctor’s appointment in a separate account. She manages proposals and response deadlines in Task Manager with her team.
She connects both Google accounts. In the Task Manager Calendar, she can see a 10:00 meeting, child pick-up at 15:30 and a proposal deadline at 16:00. The client moves the meeting to 16:30 in Google. A few minutes later, Marta sees the change, or she can sync straight away if she needs to. She checks whether she can finish the proposal in time and moves its deadline. If a colleague is assigned to the proposal task, they can see its new due date, but not events from Marta’s Google accounts.
Frequently asked questions
Does synchronisation work both ways?
Yes. Changes from Google Calendar appear in Task Manager every few minutes, while changes to Google events made in Task Manager are saved to Google straight away. New events created in Task Manager can also be added to your selected Google Calendar.
Can I connect both my work and personal accounts at the same time?
Yes, you can connect several accounts. Each connection has its own selected calendar, import window and “Disconnect” button.
Will my team see my personal calendar?
No. Imported events from Google Calendar are visible only to the user who connected the account.
What happens if I disconnect my account?
Events imported from this account will disappear from your Task Manager calendar. Nothing will change in Google Calendar, and your other connections will continue to work.
If I delete an event in Task Manager, is it also deleted in Google?
Yes. The confirmation window warns you that the event will disappear from both sides. “Undo” in the Calendar toolbar restores the event in Task Manager and creates it again in Google.
