eli5. New Year and Earth revolution

420 views

Earth celebrates several new years— according to the communities and cultures. Chinese have their own new year, westerns have their own, and so have the south asian like Nepal. I’m from Nepal, and there January 1 is not the equivalent date when we celebrate our New Year. And, that might be the case for other places too(Not sure about that tho).

So, which new year is the exact day when the Earth completed one revolution around the Sun?

From the discontinued Julian calendar, that was eventually reformed into the modern Gregorian calendar, Janus (for which January is named after) is known as the god of gateways and beginnings.

The way we mark time is a human construct by our natrual observations. We mark the days by the earths rotation, the months or “moon’ths” by the full moons. But there is no observable marker that is dominant when the moon’ths repeat. Some cultures who didn’t have an established calendar may have marked the years by winters or summers. If there was dominant star or constellation to mark the year, then the different calendars may have used that arbitrary point to sync up the mark of the new year. Who knows, if the stars in Orion were noticeable brighter than most others, we could have called it Orions instead of years.
