According to the 2003 Census report, the average commute time is 38 minutes each way for some parts of the country. That is 76 minutes each day, over 6 hours per week or 41 work days each year. If you live somewhere that has a long commute time, it is easy to see how much time is just spent driving back and forth.
If you were able to eliminate the commute even one day per week, you would save over 65 hours per year. That is over 8 work days of time or equivalent to an extra 1.5 weeks of vacation.
