TeamCal Neo is the successor of the popular TeamCal Pro. It is a web-based calendar application written in PHP and MariaDB/MySQL. It’s purpose is the day-based absence management of project teams.

TeamCal Neo’s goal was to keep the successful concept of a day-based calendar while modernizing the code-base and improving the UX with a responsive design. You can view it on any mobile device due to its responsive web design, however, its best viewed on a desktop.

TeamCal Neo supports the customization of holiday types and absence types, thus, its purpose can be altered to any graphical representation of timeline based processes or activities, e.g. a simple project plan or an event management. I have seen many great ideas of how to use TeamCal Pro that can also be done in TeamCal Neo.

The application comes in two flavors:

1. TeamCal Neo Basic (free)
2. TeamCal Neo (subscription)
