His name comes from the Middle Persian term zurwān ("Time"), which derives from the Avestan zruvā ("Time").
Words carved in stone that include the letters zrw(n) and zraovo were discovered. These words make people think that in Sogdiana and Bactria, Zurvan was worshipped like a main god.
In the third century, his name was used by the Manichaeans, for the father of greatness
