When you start to examine generations you’ll quickly note
that there is an overlap in begin and end dates of all
generations. The
baby boomer generation started in 1943
but the
builder / traditionalist generation did not end until
1944. The first member
Generation X was born in 1961 it
baby boomers are still being born until 1964.

Many wonder, “why does such an overlap exist”.
It is all a matter of what creates a culture. Because each
generation has similarities among its members they can be
recognized as a culture. As with
other cultures, generational
cultures derived from the shared experiences of the
members of the culture. We easily see this with races,
ethnicities and religions as they typically share similar
experiences and challenges throughout their life. Such is
true with generational cultures.

Consequently, in the final days of the outgoing generation or
the initial phases of the new generation babies may take on
the characteristics of either generation. This could be due to
the generation of their parents or the influence of siblings. A
baby born on the cusp of a new generation who is the
youngest in the family has a tendency to adapt the outgoing
generation. Another baby born on the same day may be the
oldest and his or her family and through normal childhood
development be more interested in the things of the younger
siblings and therefore be more likely to share their
experiences.
