For the time being, the Start date cannot be changed, as it represents a time stamp of the created task (logged activity).
We are aware this is not convenient for experiments that already happened or are still in progress, so we plan to change it in the near future. However, you can still set a due date to whichever date and mark the task as completed or leave it as it is - in progress.
What we can suggest at this point, is to do one or more of the following:
1. Add the start date next to task name (see the image below).
2. Write it in the Task Description box or Protocol Description box (see the image below).
When you click the Complete task button, the completion date of the selected task is time-stamped and this timestamp cannot be changed. You can, however, choose actions Uncomplete Task and Complete Task multiple times - these will be time-stamped as well.
