In MeisterTask, you can set a specific due date and time for each task. The due date will be displayed in the task tile as well as the task dialog.
To alert you of deadlines, the date for due and overdue tasks automatically turns yellow. MeisterTask also sends you an email notification to alert you of upcoming due dates.
To set a due date for a task, simply open the task and click on Due Date on the right side of the task dialog. A calendar will appear, which allows you to set the due date. The due time will be automatically set to 12 PM unless you actively change it.
