To ascertain any day of the week, first look in the table of years for the year required, and under the months are figures which refer to the corresponding figures, 1804 1832 1860 1888 7 347 25 7 at the head of the columns of days below. Thus: to know what day of the week 1808 1836 1864 1892 5 1 2 July 4 fell in the year 1876, in the table of leap years, look for 1876, and in a paral- 1812 1840 1868 1896 367 351 lel line, under July, is figure 6, which di- that July 4 fell on Tuesday. To find on 1816 1844 1872 Tuesday after 1st Monday in November 1820 1848 1876 to which we are guided by the figure 5 in 1824 1852 1880 1 Monday Tuesday Wednesday 3 Thursday 4 Friday 14513 6 1 4 7 2 5 7 2 Wednesday 2 Thursday 3 Friday 1 Thursday 1 Friday 1 Saturday 1 Sunday 2 Sunday 2 Monday 3 Sunday 3 Monday 3 Tuesday 4 Saturday 5 Sunday 6 Monday 7 Tuesday 8 Wednesday 4 Sunday 4 Monday 4 Tuesday 4 Wednesday 11: Sunday 11 Monday 18 Sunday 19 Sunday 19 Monday 20 Monday 20 Tuesday 21 Wednesday 22 Wednesday 22 Thursday 23 Friday 18 Monday 24 Sunday 24 Monday 24 Tuesday 25 Sunday 25 Tuesday 25 Wednesday Thursday 23 Thursday 26 Monday 25 Monday 5 Wednesday 5 Thursday 7 Friday 9 Sunday 6 Friday 7 Saturday 8 Sunday 9 Monday 10 Tuesday 11 Wednesday. 12 Thursday 13 Friday 14 Saturday 15 Sunday 16 Monday 17 Tuesday 18 Wednesday 19 Wednesday 19 Thursday 20 Friday 21 Saturday 26 Wednesday 26 Thursday 27 Thursday 27 Friday 28 Friday 28 Saturday 29 Sunday 30 Monday 81 Tuesday THE TIME OF HIGH WATER at the places following may be found approximately for each day by adding to or subtracting from the time of high water at New York the hours and minutes annexed. [Corrected at the office of the United States Coast and Geodetical Survey.] EXAMPLE.-To ascertain at what hour it will be high tide at Baltimore on the 1st of August, find the time of high water at New York under August 1st, which is 4.24 A.M., then add 10 hours 52 minutes, as found in the table of Tide Constants under Baltimore, and we have 3.16 P.M. as the hour of high water at Baltimore August 1st, 1880. NOTE.-The hours of high water in the calendar pages are the morning hours from midnight to noon-throughout the year, as computed for the U. S. Coast Survey. To find the time of next high water, or the afternoon tide-from noon to midnight-add 12 h. 25 m. in each day. The result will be the proximate hour of evening tide. For low water, add 6 h. 12 m., approximately, to the time of high water. Explanation of the Calendar. THE two natural divisions of time are the day, of 24 hours, representing one revolution of the earth on its axis, and the year, 365 days, approximately representing one revolution of the earth around the sun. The month represents (nearly) the period of the moon's revolution round the earth (about 2911⁄2 days), while the week is approximately one-fourth of this. By the Julian Calendar, established by Julius Cæsar, 46 B.C., the months were reconstructed; the Roman year, which began March 1, and had but ten months, being changed to Jan. 1, and two months added. Thirty-one days were given to the 1st, 3d, 5th, 7th, 8th, 10th, and 12th months, and 30 days each to the rest, except February, which on every fourth year received an intercalary day, made by the sexto Calendas Martius, whence "leap year" came to be called Bissextile. As the Julian year had 3654 days, its length exceeded the true solar year by 11m.14 sec., so that the equinox in the course of centuries fell back several days. To correct this error, Pope Gregory XIII. in 1582 reformed the calendar by suppressing ten days, restoring the equinox to March 21. The Gregorian Calendar also made every year which is divisible by four without & remainder a leap year, except the centesimal years, which are only leap years when the first two figures are divisible by four: thus 1600 was a leap year, 1700, 1800, and 1900 common years, 2000 a leap year, etc. The length of the mean year is 365 d. 5h. 49m. 12sec., exceeding the true solar year nearly 26 sec., which error amounts only to 1 day in 3.325 years. The Gregorian Calendar was adopted by Germany in 1700, and by English law in 1752, when the Julian Calendar, or old style, gave place to the new style, by dropping eleven days from the month of September, 1752. The festival of Easter, commemorating the resurrection of Christ, used to be observed on the 14th day of the moon, i.e., near the full moon-the same as the Jewish Passover. But the Council of Nice, A.D. 325, ordered Easter to be celebrated on the Sunday next succeeding the ful' moon. that comes on or next after the vernal equinox-March 21st; thus making Easter and the related feast and fast days movable holidays.
