# Extract date elements¶

This processor takes a column containing a date in standard ISO8601 format (ie, detected with meaning ‘Date’) and extracts various elements from this date to other columns

Each output column is optional. If you leave them empty, the corresponding information will not be extracted.

• Day of week: 1-7 (1= Monday, 7 = Sunday); a Formula with the expression x % 7 + 1 would encode Sunday as 1.
