Project Calendar in SARJ will give you a detailed view of each participants assigned tasks (rotations), working hours, shift breaks and vacations. The purpose of the calendar is to help you identify free or overloaded team members of the project, so that you can take the required steps to resolve the same.
SARJ Project Calendar calculates the time of user calendar based on Rotation type like based fixed Rotation or Round Robin Rotation.
If its Round Robin type of rotation from 11 AM to 8 PM with two participants, then calendar will assume both of the participants will be busy from 11 AM to 8 PM because tickets/task will distribute equally.
So, it assumes both of the participant will be busy during Rotation Start and End Time.
If its Fixed type of rotation from 11 AM to 8 PM with 2hr intervals and with two participants A & B, then calendar will assume that User A will be busy from 11 AM to 1 PM then User B will be busy from 1 PM to 3 PM. then for next 2 hours again user A then user B.
So, it assumes 2hr fixed assignment for each participant.
