(CNSNews.com) - President Barack Obama, who is departing Friday for a vacation in Hawaii that will reportedly last until Jan. 5, took more annual vacation days on average in his first term than the average private-sector worker gets after 20 years on the job.

Obama took an average of 21.5 vacations days per year in his first four years as president. By comparison, private-industry workers in the United States who have at least 20 years on the job get an average of 19 days of paid vacation per year.

The Government Accountability Institute, headed by Peter Schweizer (who is also a research fellow at the Hoover Institution at Stanford University), published a study of President Obama’s calendar on April 28, 2013 that included an accounting of the vacation days the president took from his inauguration on January 20, 2009 through March 2013.

According to GAI’s accounting, Obama took 21 vacation days in 2009, 34 in 2010, 20 in 2011, 7 during his re-election-campaign year of 2012, and 4 in January 2013 before his second inauguration on Jan. 20, 2013 marked the end of his first four years in office.

The 86 cumulative vacation days that Obama took in his first four years in office worked out to an average of 21.5 days per year.

Even if you do not count the four days of vacation Obama took in early January 2013—before the end of his fourth year in office on January 20, 2013—the 82 days of cumulative vacation he took in his first four calendar years in office equals an average of 20.5 per year, which is still more than the 19 paid vacation days per year that the average private-industry worker gets after 20 years on the job.

According to the Bureau of Labor Statistics , workers in private industry get an average of 10 days of paid vacation after they have been at the job one year; they get an average of 14 days paid vacation after they have been at the job five years; 17 days after they have been at the job 10 years;and 19 days after they have been at the job 20 years.
