GoodData supports the following date formats:
- ISO Date format: yyyy-mm-dd (2010-01-05)
- US Date format: mm/dd/yyyy (01/05/2010)
If a column of data that is being uploaded contains dates in one of these formats, the application will recognize it and prompt the user to map this column to the provided "Date" hierarchy. Mapping to this hierarchy allows the application to perform different aggregations based on year, month, quarter, etc.
