Happy months calendar is a poetic Artwork that depicts not only the joy that a refreshed mind could bring in our lives but also details the facts concerning the origin of our civil calendar that is universally known with the exception of few countries that are still using a calendric form different from the Gregorian calendar. I, Jean Dufralessi, as the author of this interesting poetic adventure, never cease, while writing it, to enjoy it. Through the writing of this book, I was, in addition to many French philosophers and poets, influenced by the writings of King David and his son King Solomon.King David mightily psalmodies Jehovah the mightiest God of the Universe, through diverse psalms which lyrics depict not only the Glory of God but also the poetic characteristics of that great king whose lineage's progeny: Jesus-Christ is destined to reign for ever on his throne at Jerusalem. In addition to the Davidic inspiration, I was amazed by the wisdom of his son King Salomon who with a poetic touch, left us a treasure through some books of the Bible such as: Proverbs, Ecclesiastes and Song of Solomon. In those collections, King Solomon covered a variety of subjects ranging from real intimacy between one man and one woman, love, marriage, family, love for nature, and more.The scrutinizing of each month reveals the poetic value of the cultural resources that each of the twelve months archives in itself. As the counter of our day by day, month by month activities, calendar becomes an integral part of our style of living. Therefore, the importance to get pleasure from the fullness of its treasures throughout our earthly short period of time, is highly recommended. Indeed, life is short. Even when we cross the threshold of a century, we would soon realize that yesterday was our first birthday and today is the day of our departure to Eternity.
