The tzolkinex is an eclipse cycle equal to a period of two saros (13,170.636 days) minus one inex (10,571.946 days). As consecutive eclipses in an inex series belongs to the next consecutive saros series, each consecutive Tzolkinex belongs to the previous saros series.
The tzolkinex is equal to 2598.691 days (about 7 years, 1 month and 12 days). It is related to the tritos in that a period of one tritos plus one tzolkinex is exactly equal to one saros. It is also related to the inex in that a period of one inex plus one tzolkinex is exactly equal to two saros.
It corresponds to:
Because of the non-integer number of anomalistic month each eclipse varies in type, i.e. total vs. annular, and greatly varies in length. From remainder of 0.31081, being near 1⁄3, every third tzolkinex comes close to an even number of anomalistic months, but occurs during a different season, and in the opposite hemisphere, thus they may be of the same type (annular vs. total) but otherwise do not have a similar character.
It was first studied by George van den Bergh (1951). The name Tzolkinex was suggested by Felix Verbelen (2001) as its length is nearly 10 Tzolk'ins (260-day periods). [1]
It alternates hemispheres with each cycle, occurring at alternating nodes, each successive occurrence is one saros less than the last.

Eclipses may occur repeatedly, separated by certain intervals of time: these intervals are called eclipse cycles. The series of eclipses separated by a repeat of one of these intervals is called an eclipse series.
The tritos is an eclipse cycle of 3,986.628 days . It corresponds to:
A total lunar eclipse will take place on Tuesday, March 3, 2026.
A total lunar eclipse will take place on Tuesday, June 26, 2029. A dramatic total eclipse lasting 1 hour and 41 minutes 53 seconds will plunge the full Moon into deep darkness, as it passes right through the centre of the Earth's umbral shadow. While the visual effect of a total eclipse is variable, the Moon may be stained a deep orange or red color at maximum eclipse. This will be a great spectacle for everyone who sees it from most of the Americas and western Europe and Africa. The partial eclipse will last for 3 hours and 39 minutes 32 seconds in total.
A total lunar eclipse will take place on June 6, 2058. The moon will pass through the center of the Earth's shadow.
A total lunar eclipse will take place on May 6, 2069. The eclipse will be a dark one with the southern tip of the moon passing through the center of the Earth's shadow. This is the first central eclipse of Saros series 132.
A total solar eclipse will occur on Wednesday, May 11, 2078. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth.

The full phase could be seen in Greece, Turkey, USSR, China and the Japanese island of Hokkaido. The maximum eclipse was near Bratsk and lasted about 2.5 minutes. The sun was 57 degrees above horizon, gamma had a value of 0.539, and the eclipse was part of Solar Saros 126.

An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Annularity was visible from Australia, southeastern tip of Milne Bay Province in the Territory of Papua New Guinea, British Solomon Islands, Gilbert and Ellice Islands, Tokelau, and Swains Island in American Samoa.

The moon's apparent diameter was only 0.006% smaller than the Sun's, so this was an annular solar eclipse that occurred on May 9, 1948. Occurring 7.1 days after apogee and 6.6 days before perigee, the Moon's apparent diameter was near the average diameter.
