setLayout(new GridLayout(1,1));
setSize(322,223);
setResizable(false);
Days d= new Days();

add(d);
// try{

// }catch(Exception e){System.out.println("error "+e);}
}



public static void main(String aggsp[]){

Celendar c = new Celendar();
c.setVisible(true);
c.setDefaultCloseOperation(EXIT_ON_CLOSE);

}
