Dear gretl enthusiasts, I would like to inform you about my new package named "holidays" which may be of interest for some of you. This package returns time-series with with country- specific holidays in an easy manner. Currently the package comprises holidays for Germany only. However, some events -- such as Christmas days -- are also valid for many other countries. http://ricardo.ecn.wfu.edu/gretl/cgi-bin/current_fnfiles/holidays.gfn Have fun with it, Artur
