The Due When plugin simplifies task management in Obsidian by providing quick commands to assign due dates directly within your notes. It allows users to insert dates such as the end of the current week, next week, or the month, and even a humorous 'never' option for tasks far in the future. The plugin supports customizable tags for each due date option and includes settings to determine whether end-of-month dates fall on the last calendar day or last weekday. This tool streamlines organizing tasks and deadlines efficiently.
