Historical dates
July 4 and August 2: two milestones in one declaration
Adopting a document and signing its engrossed copy are different events.
Read the milestone, not just the document title
The National Archives timeline distinguishes July 4, 1776, when the Declaration of Independence was adopted and printed, from August 2, when delegates began signing the engrossed parchment. Not every signature was added on the same day. Calling July 4 the date of every signature compresses a process into a familiar holiday and loses a distinction that the archival record makes clear.
Compare the anniversaries honestly
July 4 and August 2 are separated by 29 days. Four complete weeks account for 28 of them, leaving a one-day difference. Their recurring anniversaries therefore never fall on the same weekday within a given year. For example, in 2026 July 4 is Saturday and August 2 is Sunday. Both dates follow February, so a leap year shifts their weekdays together rather than removing that difference.
A useful historical question
This is a case where two events are deeply connected historically without sharing an Always date relationship. The calendar result cannot measure their importance or replace the underlying history. When building your own comparison, label adoption, signing, announcement and entry into force separately where relevant. A source can support several dates for different stages without contradicting itself. Choosing the correct stage makes the resulting calendar question clearer, whether the answer is Always, Sometimes or Never.
