The purpose of the calendar is to avoid overlapping activities in the same region. You can check this calendar to see when there are other activities, to make sure your activity does not suffer concurrency from other activities.
If you need to delete or edit your activity later, please contact email@example.com
This is a try-out version, we can change the user-settings when necessary.
