After using myanimelist as a source for duration's I came to the conclusion that it would take you :
18084 minutes of non-stop watching which equals to
301.4 hours of non-stop watching which equals to
12.5 days of non-stop watching Naruto.
So you could finish watching all of Naruto in less then 2 weeks. Taking breaks and real life into consideration this would be quite a bit longer. A regular fan with a job etc etc will watch around 5-6 episodes per day, or roughly 2 hours a day. Making the time to completion roughly 150.7 days Meaning you could still finish the series well under half a year.
Actual series
Naruto 220 episodes, roughly 23 minute's a episode

Naruto Shippuuden currently at 453 episodes, roughly 23 minutes a episode
~10419 minutes or 173.7 hours or 7.2 days.

Small side note, I feel sad for the people that had to wait weekly from episode one. That's 702 weeks (not counting double releases and breaks) of waiting 6 days for the next episode (more than 13 years)
