As you all know, you can subscribe TickTick tasks into your Calendar application. To further narrow the boundary between calendar & TickTick, now, you can subscribe calendar events into TickTick web interface.
At this moment, this feature is exclusive to Pro users.
First, enable ‘Calendar Subscription’ in 'Labs’
Then, in 'list view’ section of the left panel, you will see the 'Calendar Subscription’ folder with a ’+’ icon
Click on the ’+’ icon and add the Calendar URL in the pop-up dialog window
In addition to the web interface, you can subscribe calendar into TickTick Android app as well.
