[Remind-Fans] advanced warning of first wednesday of every month?

[Jason Lewis]

Hi Guys,

I'd like to remind myself of an event that occurs on the first Wednesday
of every month.

Specifically, I want a reminder 7 days before, 3 days before, 1 day
before and on the day.

How do I achieve this? I intend to call remind once per day from a cron
job so that remind can email me the reminder.

This is what I have tried, but I'm not sure its correct.

FSET _wfun(x) choose(x, 7, 3, 1 ,0)
REM Wed 1 WARN _wfun MSG %b is first Wednesday of month


Also, how does one go about testing the more complicated remind schedules?

Thanks,

Jason
