ChronoLink allows setting up synchronization connections between different calendars, but also between and with other calendar-like systems.

Here are some examples of what it can do for you, automatically:

  • Block time on your work calendar for appointments in your private calendar, like picking up kids from school or seeing a doctor. Choose which event details to include.
  • Synchronize two work calendars to display your real availability on both sides.
  • Connect a time-tracking app or issue tracker to your calendar, so you can easily check whether you forgot to track something without leaving your calendar app.
  • Automatically block time for official/religious holidays in your work calendar.


  • Synchronize calendars within one system or connect different systems - see the list below.
  • Supports custom rules regarding which events to include and how to transform them. For details, check our Examples and the full Reference.
  • Can access not only your primary calendar, but also secondary calendars that you created, calendars shared with you or third-party calendars you subscribed to.
  • Synchronization connections can run periodically or be triggered manually.
