17520 hoursIt depends on what years they are if it is no leap year 8,760 with a leap year 8,761
87648 hours, or 87672 depending on if there are 2 or 3 leap years during the period of time.
Assuming that none of the thirteen years is a leap year, there are 24 x 365 x 13 = 113880 hours in 13 years.
The exact number will depend on the number of leap years in the 14 years: 3 or 4. So the number of hours is 8,832 or 8,856. there are 8760 hours in year at 365 days x 24 hours per day That is 8760 x 14 = 122,640 hours in 14 years. But 3 or 4 years will be leap years, depending on what year you start with, so you need to add 72 or 96 hours
In any thirty year cycle, there can be either seven or eight leap years. For example, between 2012 and 2042, there are eight leap years, and between 2013 and 2043, there are seven leap years. In a thirty-year cycle in which there are 7 leap years, this is equal to (24 x 365 x 23) + (24 x 366 x 7) = 262968 hours. In a thirty-year cycle in which there are 8 leap years, this is equal to (24 x 365 x 22) + (24 x 366 x 8) = 262992 hours.
