A calander year contains either three or four seasons, depending on how the seasons are split up or reckoned. Whether it is reckoned as three or four seasons, a calander year still consist of twelve complete lunations or moon cycles. Sometimes (every 2 - 3 years), there is an additional moon cycle in a calander year, because the length of lunations varies depending on how close the moon is to the earth at any given time at which it cycles, as well as other reasons.
I know that advice is given in Tibetan Medicine for diet and lifestyle by season. The reason being that certain elements are dominant during certain seasons and this can disturb humours, effect digestion, etc.-- we accumulate certain things more at certain times. However, I also know that ancient people marked time by lunar phases. Specifically, the full moon (the end of a lunation) is the time where things come to completion. So, I was wondering if there is any extant advice for diet, behavior, cleanses etc., taught by lunations, that is to say for each of the individual 12 moon cycles in a calander year (whether over 3 or 4 seasons).
Thanks,
Kevin
