Dear Diary Day

Celebrated on 09/22/2026

Quick Fact

Dear Diary Day, observed annually on September 22, encourages people to reflect on their thoughts and experiences through journaling. The date was chosen to mark the birthday of Samuel Pepys, whose 17th-century diaries provide a vivid account of life in London, including the Great Fire of 1666.

Origins and Establishment of Dear Diary Day

Dear Diary Day was created in 2015 by John-Paul Flintoff, a British journalist and author, to promote the benefits of journaling. The date, September 22, was chosen to honor Samuel Pepys, the famous English diarist born on that day in 1633. Flintoff aimed to inspire people to record their daily lives, thoughts, and feelings, much like Pepys did with his detailed accounts of 17th-century London.

Evolution and Modern Commemoration

Since its inception, Dear Diary Day has grown through social media campaigns and community events. Schools and libraries often host writing workshops, while online platforms encourage participants to share excerpts (anonymously or publicly). The day now emphasizes digital journaling as well, with apps and blogs providing new mediums for self-expression. Many use it as a starting point to develop a lifelong journaling habit, reflecting the enduring appeal of personal reflection.
