From the world of phenomena to space-time knowledge
Calendarization of life
Conventionally I address today as 10th September 2025. I did relevant organized activities according to this relative periodisation that we normally call calendarization of the financial year.
I may call it “calendarization” of the “life itself” because despite all the maniac and scrupulous separations of all simple tasks and everything related to them to accelerate, improve and make more and more profit strategically which will never get anywhere but only to continuous processing - calendarization helps people to establish healthy relations and communicate what they wish without disturbing their individual and collective rhythm of life. This is life!?
Time is repeated motions of nature
Time is just the measure of repeated motions of the world of phenomena. Without this periodicity we cannot measure time. We have no other means to do this. So, our knowledge of time is all about the world of phenomena or natural world. No one can perceive, conceive or apprehend unquantified time. Thus, periodicity is the base of our knowledge of everything concerning time.
Experience of pulsation
Every living human being is experiencing necessarily the pulsations of the heart. It denotes the life and activities of an individual. Therefore, all our activities are connected with the pulsations of the heart. From birth to processes of growth, processes of decay and until death each human has to wiggle according to his/her rhythmical throbbing.
Seasons of the year
Beyond this rhythm of the heart, man also depends on the long period pulsations of nature: seasons – spring, summer, autumn and winter. All changes of plant life directly but involuntarily affect the knowledge of time. This is on the other hand enriched by the life and behaviour of animals, birds and all insects. Regarding so-called inanimate phenomena I have my own direct experience to share here. I visited my hometown after 20 years and I found, first, the landscape of the town had changed. The riverbank and the sea beach changed unrecognizably. In brief, after 20 years I found the geographical area had increased (due to the river and the Indian Ocean 's activities) and nature was more vigorous than before. This means that change, decay and transformation are always in action, even where human beings cannot notice immediately.
Organized time studies
We have then rudimentary astrology and more scientifically founded astronomy and rigorous astrophysics of 21st century to note the periodicity of the sky, its contents, their behaviour and their connection with us. From these we achieve very important and more effective periodic motion knowledge that helps our man-made world processes. This knowledge is therefore very important because it directly affects everything including human beings.
Rotation and revolution of the earth
Thus, the rotation and revolution of the Earth are the two most important periodic motions for human beings and the rest of existence. They can immediately observe and experience the relation with the life processes of individual and collective activities. What we habitually call “day and night” is the result of the rotation of the Earth. We know about the revolution of the Earth, but the effect of this annual revolution is more visible in the floral world. therefore, the rotation and revolution, both movements of the Earth, are affecting relatively everything this planet contains. Despite all what I have said due to my (or any human's) constraints and limits in general and the delay in understanding the complex and complicated micro processes (movement, change, decay, transformation) of total existence, I may think erroneously that "time" as an objective phenomenon.
Conclusion
Well, then our knowledge of time, necessarily depends on the periodicity of the world of phenomena and the rotation and revolution of the Earth. This factual knowledge corresponds to our reality.
