# Date controls

Date controls in your study are represented in different ways in the InForm Ad Hoc Reporting tree. Some dates are stored as numeric values, and others are string values. For example, for a start date for an adverse event, the date control could appear as Date ~ Start Date, Month Yr ~ Start Date, and so forth, depending on your study design. This format determines the data that appears in ad hoc reports.

In addition, the format for dates in the Reporting and Analysis module is determined by Cognos settings, and locale settings for your InForm study.
