Calendar lets you imagine issueses in the Month, Week, and Day
Any user can create an unlimited number of calendars.
You can create calendars for different cases: planning a specific project or product, employee, group of employees or the special issue types (such as a vacation or a business trip, or marketing activities)
Also you can add to your calendar Quick Filters to highlight certain issueses or/and temporarily hiding them on the calendar
You can add a new or existing issue to calendar.
There is a polite license policy for HelpDesk needs.
Let's see the User's Guide to lean basic functions.
