You want to change the date format for a Birth Date field. For example, you may have a Profile Form that is showing the Birth Date format in dd/mm/yyyy, but you want it to display in mm/dd/yyyy.
The format of the date fields in NetCommunity are controlled by the culture settings on the Raiser's Edge and NetCommunity databases. If you notice the date format is showing incorrectly for a form, this may indicate the format has become stuck or corrupt. To resolve, create a new part, not a copy, of the same part type. This should allow the culture settings to be properly reflected.
