What year would you graduate if you were born in 1956?

In the United States, if you were typical and started first grade when you were 6 years old (in 1995), and went through all 12 grades in a normal fashion, then you would have graduated from high school in 2007.

School districts generally have birthday cutoff dates which could affect that. If the district says you have to be 6 years old by October 1 to enter first grade, and your birthday was November 30, then you wouldn't have started school until 1996 and high school graduation would have been 2008.
