Note. In Circular Motion, the minuend is sometimes less than the subtrahend, as in Ex. 29, in which case it must be increased by 12 signs.

FIRST OPERATION.

y

mo.

da.

ART. 103. To find the time between two different dates.

Ex. 1. What is the difference of time between October 16th, 1842, and August 9th, 1844 ? Ans. ly. 9mo. 23da.

Commencing with January, the first

month in the year, and counting the Min. 1844 7 9 months and days in the later date up to Sub. 1842 9 16 August 9th, we find that 7mo. and 9da.

SECOND OPERATION.

have elapsed ; and counting the months Rem. 1 9 23 and days in the earlier date up to Octo

ber 16th, we find that 9mo. and 16da. Min. 1844

have elapsed. Then, setting down the 8 9

earlier date under the later, and placing Sub. 1842 10 16

the months and days at the right of the Rem. 1 9 23

year of each date respectively, as in the

example, we subtract the lower number from the upper, and the remainder is the time between the dates.

RULE. Set down the earlier date under the later, writing the year of each on the left, next after this the number of months that have elapsed since the beginning of the year, and on the right the day of the month. Then subtract as in the preceding rule.

Note. – 1. A month in legal transactions is reckoned from any day in one month to the same day of the following month ; but in computing interest for less time than a month, and in finding the difference between two dates, 30 days are considered a month, and 12 months a year.

Some prefer reckoning the number of the given month, instead of the number of months that have elapsed since the beginning of the year; the result is the same in both cases.

See ad operation.

Ans. 3y. Imo. 15da. 3. A note was given Nov. 15th, 1832, and paid April 25th, 1837; how long was it on interest ? Ans. 4y. 5mo. 10da.

4. John Quincy Adams was born at Braintree, Mass., July 11th, 1767, and died at Washington, D. C., Feb. 23, 1848; to what age did he live?

Ans. 80y. 7mo. 12da. 5. Andrew Jackson was born at Waxaw, S. C., March 15th, 1767, and died at Nashville, Tenn., June 8th, 1845 ; at what age did he die?

Ans. 78y. 2mo. 23da.

QUESTIONS. — Art. 103. From what period do you count the months and days in preparing dates for subtraction? How do you arrange the dates for subtraction ? How subtract? How many days are considered a month in business transactions ? What is the second method of preparing dates for subtraction ?
