THE AMERICAN ALMANAC, FOR THE YEAR 1844, Being the latter part of the 68th, and the beginning of the 69th, year of the Independence of the United States of America; แ the 6557th year of the Julian Period; the latter part of the 5604th and the beginning of the 5605th, year since the creation of the world, according to the Jews; the 2597th year (according to Varro) since the foundation the 2591st year since the era of Nabonassar, which has been the latter part of the 1259th, and the beginning of the 1260th o Conjunction, or having the same Longitude or Right Ascension. Quadrature, or differing 90° in The sign is prefixed to the latitude, or declination, of the Sun, or when south; but the other heavenly body, when north, and the sign former prefixed to the hourly motion of the Moon in latitude, indicates that she is approaching, and the latter that she is receding from, the north pole of the ecliptic. The letters M. A., m. a., denote Morning and Afternoon. 46 แ Autumn d. h. m.

The Mahometan Era dates from the flight of Mahomet to Medina, July 16th, A. D. 662. The Mahometan year is purely lunar; it consists of 12 synodical periods of the Moon, or of 354 days, 19 times in a cycle of 30 years, and 11 times of 355 days. The average length of this year is therefore 354 days, which differs only thirty-three seconds from the truth; a degree of exactness that only could have been attained by a long series of observations. But as no allowance is made for the excess of 11 days in the length of a tropical year over the time of 12 revolutions of the Moon, it is obvious that in about 33 years, the above months will correspond to every season and every part of the Gregorian year. |
