Order no. 231.WZU

Cardboard construction set for a triple rotating calculating disc, with which the time difference between our time (CET) and the solar time (true local time) can be determined, which can be up to 50 minutes with us, in western Spain even 98 minutes. A practical help for everyone who wants to have the “natural time” determined by the sunset in his consciousness, in addition to the time determined by convention. Also suitable to align sundials.
