Relative Dates - Taskpaper to Omnifocus

Last update about 2 years ago


This action sends a Taskpaper-formatted tasklist to OmniFocus. It asks for a baseline date and parses the draft for date fields to insert a date relative to the base date.

Date field format

The format is:
For example <<+3>> means 3 days after the given base date. Negative numbers are possible, e.g. <<-5>>.

Use in taskpaper

The fileds can be used in the @defer() or @due() parameters of a task. An example:

Gardening Project
    - Sow flower seeds @defer(<<+0>>)
    - Water the flowers @defer(<<+2>>)
    - Pick the flowers @defer(<<+5>>)

This will set the defer dates for the first task to the base date, the second task two days and the third task 5 days after the base date. The project will be send to OmniFocus right into projects.
