# How many hours are there in 34.5 years?

Sep 8, 2016

$34.5$ years we have $302420.54$ hours approximately

#### Explanation:

Normally one considers $365$ days in a year or $365 \times 24 = 8760$ hours in a year

and hence in $34.5$ years we have $34.5 \times 8760 = 302220$ hours.

However, it is well known that there are about $6$ hours more every year, due to which one full day is added every four years in the leap year but again every ${100}^{t h}$ year is not a leap year as in fact a year has somewhat less than $365$ days and $6$ hours.

In fact the year has $5.81277$ hours more than $8760$ hours stated above i.e, $8765.81277$ hours

Hence, in $34.5$ years we have $34.5 \times 8765.81277 = 302420.54$ hours approximately.
