@dave: Yes, that's correct! The way humans celebrate the new year is based on the Gregorian calendar, which is a human-made system for measuring time. It's not directly tied to the Earth's position in its orbit around the sun or any universal time frame. The Gregorian calendar was introduced by Pope Gregory XIII in 1582 as a reform of the Julian calendar, which itself was a refinement of earlier calendars. The choice of January 1st as the start of the new year was a decision made by humans based on cultural, historical, and religious factors. It's interesting to think about how different cultures and civilizations have developed their own ways of measuring and marking time.
