 The seven operas were not composed in " weekday order " but rather starting ( apart from Jahreslauf in 1977 , which became the first act of Dienstag ) with the " solo " operas and working toward the more complex ones : Donnerstag ( 1978 – 80 ) , Samstag ( 1981 – 83 ) , Montag ( 1984 – 88 ) , Dienstag ( 1977 / 1987 – 91 ) , Freitag ( 1991 – 94 ) , Mittwoch ( 1995 – 97 ) , and finally Sonntag ( 1998 – 2003 ) ( Stockhausen @-@ Verlag 2010 , 3 – 7 , 26 – 48 ) .
