It is believed that calendars and attempts to document time into the future began with the Egyptians – a form of writing and math was necessary.
Actually, attempts to identify seasonal changes can be traced as far back as Pagan monoliths.
As it turns out, most modern calendars to date are religious based, the Chinese calendar being the exception.
The error in all calendars has occurred because of the attempt to align seasonal changes (the earth’s orbit) to moon phases (the new moon) which can vary anywhere from 29 to 31 days.
Earlier Christian calendars shifted the New Year between March and January – finally settling on January 1.
In the typical way of religion, science and common sense has been eliminated in order to justify calendars the conforms to religious dogma.
Nature’s new year began on December 21st. However, for the sake of conformity I wish you all a Happy January first.
