About National Letter Writing Day

National Letter Writing Day is an informal observance held on December 7.

Institutional sources from the University of Michigan and Smithsonian document the date while leaving the observance’s original creator unclear.

Why National Letter Writing Day matters

The day encourages handwritten correspondence and reflection on letter-writing traditions.

Its cultural use is well documented, but the reviewed evidence does not support converting a later popular attribution into a verified founding claim.

History of National Letter Writing Day

The University of Michigan’s Clements Library published a National Letter Writing Day feature on December 7, 2009 and explicitly said the origins of the observance were unclear.

The Smithsonian National Museum of American History published a feature in December 2013 identifying December 7 as National Letter Writing Day.

The 2009 institutional evidence means later claims that the observance was first created after 2009 cannot be accepted without resolving the chronology.

No reviewed government source establishes statutory public-holiday status.
