According to the White House, the President doesn't work all that much. During the month of May, which included 21 working days, President Obama claims he worked about 92 hours (91.95 to be exact). That's according to the White House schedule, posted on the whitehouse.gov Website. That equates to an exhausting 4.4 hours per day. Excluding his grueling G8 summit travels during the week of May 23 (when he was forced to endure eight hour work days!), Mr. Obama worked an average of 3.25 hours per day when at the White House in May.
