, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a

Solar eclipses of 1801–1805

The partial solar eclipses on April 13, 1801 and October 7, 1801 occur in the previous lunar year eclipse set, and the solar eclipses on January 1, 1805 (partial); June 26, 1805 (partial); and December 21, 1805 (annular) occur in the next lunar year eclipse set.

Saros 112

This eclipse is a part of Saros series 112, repeating every 18 years, 11 days, and containing 72 events. The series started with a partial solar eclipse on July 31, 539 AD. It contains total eclipses from March 15, 918 AD through November 18, 1332; hybrid eclipses from November 30, 1350 through April 29, 1585; and annular eclipses from May 11, 1603 through June 23, 1675. The series ends at member 72 as a partial eclipse on September 19, 1819. Its eclipses are tabulated in three columns; every third eclipse in the same column is one
