Database Design For Schedule Task

Hi there

I am trying to copy what is happing in "Schedule Task" on Windows and put into database design below. It's a denormalisation though.

What is the better way to handle this schenario such as DAILY, WEEKLY AND MONTHLY TASK? I did try put into normalisation by adding extra table called ScheduleDetail which holds DAYS and MONTHLY but it's more complicated.

Anyway .. I am waiting your comment or anything.
