Calendar
Why would one month be shorter than the other? Does the moon revolve slower around the earth in January, so it takes 31 days to complete an orbit instead of 28?
Neo, from the film The Matrix could have said about the Julian Calendar that it was just another system of control. The Julian Calendar cuts our link with our own natural rhythm. The only thing this calendar can do is to make Spring start when the calendar indicates March or April. Other than that the calendar doesn’t make any sense at all, when you look at how time cycles work.
I don’t mean to offer you a different kind of Calendar in this book, nor to explain why or how to use it. There are other books that do exactly that. But, realize that when you are on the path of colourcash, the calendar is one of these things you will come across.
