What is the collective term for "Daily", "Weekly", "Monthly" and "Yearly"?

I am developing a business application in which the user can select from one of these options, namely "Daily", "Weekly", "Monthly" or "Yearly", for scheduling appointments. I need to create a field in the database to hold this value, but am at a loss for what to name the field.

What would be the collective term? In Outlook, the combination of the option plus the option-specific sub-options is headed "Recurrence pattern", but that obviously applies to the complete selection. I am only interested in the collective term for "Daily", "Weekly", "Monthly" and "Yearly".

Perhaps just "recurrence"?

Solution 1:

Periodicity:

• The quality or state of being periodic; recurrence at regular intervals.

(AHD)

Solution 2:

You could always use headings like Time or Frequency in your application. I would say frequency sounds better than recurrence here.
