GTD Tickler file – a proposal for text file format

Taskwarrior is also built upon the todo.txt format. [1]<p>Taskw supports various task dates – { due: scheduled: wait: until: recur: } [2]<p>Taskw supports various named dates like soq&#x2F;eocq, som&#x2F;eom (start&#x2F;end of [current] quarter, start&#x2F;end of month), tomorrow, later [3]<p>Taskw recurring tasks (recur:) use the duration syntax: weekly&#x2F;wk&#x2F;w, monthly&#x2F;mo, quarterly&#x2F;qtr, yearly&#x2F;yr, … [4]<p>Pandas has a &quot;date offset&quot; &quot;frequency string&quot; microsyntax that supports business days, quarters, and years; e.g. BQuarterEnd, BQuarterBegin [5]<p>IDK how usable by other tools these date string parsers are.<p>W&#x2F; just a text editor, having `todo.txt`, `daily.todo.txt`, and `weekly.todo.txt` (and `cleanhome.todo.txt` and `hygiene.todo.txt` with &quot;## heading&quot; tasks that get lost @where +sorting) works okay.<p>I have physical 43 folders, too: A 12 month and a 31 day expanding file.

Been a long term practitioner of GTD, I adopted todo.txt about 7-8 years ago and never looked for tools after that! I created something similar for the tickler file as well. Would love to get some feedback.
