The project management calendar templates can be designed in EdrawMax as the tool offers hundreds of free roadmap symbols and templates. These templates are 100% customizable and can later be shared in multiple formats as required. It should be noted here that the project management calendar defines the working and non-working days and times for tasks. This calendar usually represents the organization's traditional working hours. A project manager uses this project management calendar to understand the timeline for different projects, client calls, project team meetings, and other important conference calls. All the team members can access this monthly project calendar and understand how the company's days are divided in the entire month.
