30 MEASURE OF TIME. 



RULE. I. When the dates are in the same year, subtract 

 the number of days of the earlier date from the number 

 of days of the later date ; the result will be the number 

 of days required. 



II. When the dates are in consecutive years, subtract the 

 number of days of the earlier date from 365, and add to 

 the remainder the number of days of the later date; the 

 result will be the number of days required. 



When the year is a leap year, add one day to the result.
