Theories are explanations for natural phenomena based on facts which produce correct predictions. So, you need a LOT of foundational evidence and correct, testable predictions.
Natural phenomena pay no attention to any particular calendar. Quite the reverse, calendars are based on certain natural phenomena.
The scientific definition of scientific inquiry is the ongoing process of discovery in science. It is the diverse way in which scientists study the natural world and its processes to come up with facts to back up their theories.

Lucretius advocated for a materialistic philosophy that emphasized the idea that all things are composed of physical matter. He believed that the universe operates solely based on natural laws and interactions between particles. Lucretius heavily opposed supernatural explanations for natural phenomena.

The National Science Education Standards defines scientific inquiry as "the diverse ways in which scientists study the natural world and propose explanations based on the evidence derived from their work. Scientific inquiry also refers to the activities through which students develop knowledge and understanding of scientific ideas, as well as an understanding of how scientists study the natural world."

This is referred to as a scientific theory. Scientific theories are explanations that are well-substantiated.
