As far as I know the date format in Excel does not support dates before 1900. Gretl does. If you are transferring time series data from Excel to gretl then the dates on the Excel file must be in Excel date format. Libre Office (or Open Office) Calc does support dates before 1900 and can read Excel data files.

Best regards

Hello

Please, I can go down as the year of the series from 1700 to 1580?
When I download the Excel data the system will not let me do it!

Thanks!
