About National Family Health History Day
National Family Health History Day is a U.S. public-health observance held on Thanksgiving. It grew from the U.S. Surgeon General’s Family History Initiative launched in 2004 to encourage families to learn and record useful health history.
Federal sources used the shorter name “National Family History Day” in the original 2004 declaration and later used “National Family Health History Day.” This guide treats those names as the documented history of one Thanksgiving observance, not as separate holidays.
Why National Family Health History Day matters
Family health history can give healthcare professionals useful context about conditions that may occur more often in a family, but it does not predict with certainty whether an individual will develop a disease.
Health information is personal. A useful family conversation is voluntary and respectful: relatives may choose what they are comfortable sharing, and no one should be pressured to disclose diagnoses, genetic-test results or other private medical information.
History of National Family Health History Day
On November 8, 2004, HHS announced the Family History Initiative. The same federal release says U.S. Surgeon General Richard H. Carmona declared Thanksgiving Day to be the first annual National Family History Day.
A 2005 federal release called that Thanksgiving the second annual National Family History Day, confirming continuity from the 2004 launch.
Later NHGRI material uses the name National Family Health History Day and says the Surgeon General has recognized Thanksgiving that way every year since 2004. CDC and NHGRI continued family-health-history education around Thanksgiving and the My Family Health Portrait tool.
The reviewed sources therefore support a naming evolution from the original National Family History Day wording to the later National Family Health History Day wording without establishing a separate second observance.

How to Observe National Family Health History Day
If relatives are comfortable, ask broad questions about health conditions that occur in the family and write down only information people have agreed to share.
Use a trusted family-health-history tool or a simple private record to organize information, and keep sensitive health details secure rather than posting them publicly.
Share relevant family history with an appropriate healthcare professional when it could help inform screening or care decisions; do not use a family history by itself to diagnose yourself or another person.
Respect a relative who does not want to discuss a diagnosis, cause of death, genetic result or other private information. Participation is useful only when it is voluntary.
Update family health history over time as relatives choose to share new information, rather than treating a Thanksgiving conversation as a complete medical record.
