Question

I am doing some calculations to see how many hours of light does a specific location (identified by latitude and longitude) has in a specific day of the year. Contrary to my expectations I get a slight variance for different years. See the data calculated for this point in Svalbard (77.553604,23.670272) in the same day for different years. The values are calculated using the same formula and the same coordinates.

2005-02-22 5.84500
2006-02-22 5.76472
2007-02-22 5.68389
2008-02-22 5.60222
2009-02-22 5.85472
2010-02-22 5.77472
2011-02-22 5.69389
2012-02-22 5.61250

Is this normal and why so?

Explanation / Answer

Of course it's normal. Most of the variation in your table is controlled by the leap years. Note that in 75% of the years, the number of hours drops by ?0.08
