For events that happen on a reoccurring basis, the Repeat fields are chosen.

The repeats can be:

• Every day
• Every so many days
• Every number of weeks on what day
•     the until field is when to stop the repeats.
• On the number day of the month
• Monthly by data
• Yearly by date

If there are circumstances where one of the reoccurring events falls on a date when it cannot happen, create the Repeat field.  Then go to the date with an exception and choose to ignore the event of that date.
