1	Current Date and Time (UTC)		The dates below on the LEFT are even 45° divisions of the solar year using the modern system of ecliptic longitude. This is the system that was used by the now defunct archaeoastronomy.com website. The dates on the RIGHT are determined by more evenly dividing by time, although they do start with the scientifically determined moments of solstices. Scroll further to the right for an even more simplified system that simply fixes the day count intervals (in a way much more like a calendar system would be put together) so that the dates of approximate solstices and 45 or 46 day intervals remain constant. If you have a Google account you can click 'File' then 'Make a Copy' so that you can make edits to preference settings, UTC offset amounts, etc.												Mar 22	45	This is a fixed-date calendar based	Apr 13	16th Divisions
