Labor Day is a federal holiday in the United States celebrated
on the first Monday of September to honor and recognize the
American labor movement and the works and contributions of
laborers to the development and achievements in the United
States.

Beginning in the late 19th century, as the trade union and labor movements grew, trade unionists proposed that a day be set
aside to celebrate labor. "Labor Day" was promoted by the
Central Labor Union and the Knights of Labor, which organized
the first parade in New York City. In 1887, Oregon was the first
state of the United States to make it an official public holiday.

By the time it became an official federal holiday in 1894, thirty
states in the U.S. officially celebrated Labor Day.

During the 1890s, publications were inserted into Joseph
Pulitzer‘s New York World and William Randolph Hearst‘s
New York Journal.

In November 1896, Morrill Goddard, editor of the New
York Journal from 1896 to 1937, launched Hearst’s
Sunday magazine, later commenting, "Nothing is so
stale as yesterday’s newspaper, but The American
Weekly may be around the house for days or weeks
and lose none of its interest."

In Philadelphia, Pennsylvania on July 4, 1776, the Continental

proclaimed the independence of the United States of America
from Great Britain and its king.

In what is now known as Juneteenth, on June 19, 1865, Union
soldiers arrived in Galveston, Texas with news that the Civil
War is over and slavery in the United States is abolished.

A mix of June and 19th, Juneteenth has become a day to
commemorate the end of slavery in America.

Despite the fact that President Abraham Lincoln’s Emancipation Proclamation was issued more than two years earlier on January
1, 1863, a lack of Union troops in the rebel state of Texas made
the order difficult to enforce.

Some historians blame the lapse in time on poor communication
in that era, while others believe Texan slave-owners purposely
withheld the information.
