In Breaking Bad Mexico looks very rural and the US also look rural sometimes. So I am curious to know what time frame Breaking Bad is taking place at.
We can then assume 2009 is when Walter White turns 50 years old due to his birth year being listed as 1959
From this, the final episode Felina takes place in 2011, exactly on the day of Walter's 52nd birthday.
Actually it was set in 2002 and we can clearly see the the date as 2003-11-30 in the episode 3x03 from the case number.
