how many years from the year 1845 to 2015?

169 full years are IN BETWEEN 1845 and 2015.

From 1845 to 2015, INCLUSIVE, is 171 years.

But if you want the interval, i.e.:
From the beginning of 1845 to the beginning of 2015 is 170 years.
From the middle of 1845 to the middle of 2015 is 170 years.
From the end of 1845 to the end of 2015 is 170 years.

2015 - 1845 =170 years.

From january 1 , 1845 to December 31, 2015 . It is 171 years.

Substract 1845 from 2015 = 170

55 + 100 + 15 = 170

Y = ( 2015 - 2000 ) + ( 2000 - 1900 ) + ( 1900 - 1845 )

Y = ( 15 ) + ( 100 ) + ( 55 )

Y = 170 years <----------------------------------------

From 1 January 1845 to 31 December 2015 = 171 years
Usual calculation is to subtract the smaller number from the larger one 2015 - 1845 = 170

170

net years ( excluding year 1845 and year 2015 ) : 169 years ,
gross years ( inclusive year 1845 and year 2015) : 171 years

From 12am January 1st 1845 to 12am December 31st 2015 would be 171 years unless you take leap year into account u would have to subtract 42.75 days so that brings you back to 170 years 322.25 days

Subtract the little number from the big number.
2015-1845=170
or...
x+1845=2015
x=2015-1845
x=170

there are 170 years from the year 1845 to 2015

170 years.
