Days Until US Thanksgiving (reference)

About US Thanksgiving (reference)

US Thanksgiving is statutorily defined as the fourth Thursday in November, a date fixed into law in 1941 after decades of presidents individually proclaiming the holiday's date each year (Abraham Lincoln first nationalized the observance in 1863 during the Civil War).

Being pinned to a weekday rather than a specific numbered date, it can fall anywhere from November 22 to November 28 depending on the year — the calendar mechanics behind that range are the same ones covered on the Business Days Calculator and Add Business Days Calculator, just applied to a whole-month search instead of a short span.

Since Black Friday and Cyber Monday are both defined relative to Thanksgiving's own fourth-Thursday rule, all three holidays' dates move together as a connected block from year to year rather than independently.

Sarah Josepha Hale, a magazine editor and writer, campaigned for decades before persuading Lincoln to establish a national Thanksgiving date in 1863, a lobbying effort now considered one of the more successful single-issue advocacy campaigns in early American history.
