Looks good! I will soon be able to schedule my car visits to the garage :)

A few remarks, though:
- For consistency, please use camelCase naming for Recurrence methods

- It would be nice to have some unit-tests for this feature

- The syntax to specify the weekday in case of weekly recursion could be
made a bit more forgiving: for example allowing full day name and
localized day name instead of only using the first two chars.
I also suggest lowercasing the whole line before parsing it, to ensure
we do not reject a day written with an upper-cased first letter.

- What do you mean with "recurrence table should fill up and a cleanup
process should be defined"?
