There are only two days in the year
when nothing can be done.
One is called yesterday and the other is called tomorrow,
so today is the right day to love, believe,
do and mostly live.
There are 365 days in a normal year. 366 days are in a leap year which comes every four years. In 2010, there are 365 days while in 2012, there are 366 days in the year. Because it takes the earth 365 and 1/4 days to go completely around the sun.
A negative percentage means the Comparison Year was more mild than the Base Year. A positive percentage means the Comparison Year was more severe than the Base Year. When the monthly degree days in either the base year or the comparison year are less than 30, a percentage comparison is not calculated. However, the Annual Total comparison percentages include all heating and cooling degree days.
