Tritos


The tritos is an eclipse cycle of 3986.628 days.
It corresponds to:
The length of the tritos is equal to the length of the inex minus the length of the saros eclipse cycles. Therefore, eclipses that occur 1 tritos apart, belong to two different saros series with series numbers that differ by one.
The pre-Columbian Maya used a calculation in their own observations of eclipse cycles in which a period of three tritoses was approximated by 11960 days, based on 46 periods of their tzolk'in calendar. The number of anomalistic months in a tritos, having a fraction near, means every third eclipse is in nearly the same position in the elliptical orbit, so eclipses will have similar timing and total versus annular quality.
Solar and lunar eclipse event dates will repeat on this cycle for about 700 years.
