if you had taken the current june calendar day wa VIII is the day 11th June 2006 you toss the coin right?
in that case another day t or c in western calendar of june will be on the 28th and 29th june respectively. hope this will help.
you can check on alex chiu calendar and see how the same pattern is repeated all over again. there is 12 element and in 10 numbers. you only have to know which element starts first and what follow after the other. and what numbers comes with the first element. its very simple. when u understand this. u can simply make one of your own chinese calendar in collaboration with the western one.
