Army Birthday – June 14, 2024

Join the celebration of the U.S. Army Birthday on June 14 as we remember its creation in 1775. The army originally consisted of volunteer soldiers with roots to the Continental Army — and was formed to fight the Revolutionary War. Today, as the largest branch of the U.S. military, the proud men and women of the U.S. Army continue to provide peace and security for all of us.

When is Army Birthday 2024?

Happy birthday to the U.S. Army on June 14! What started off as mostly a volunteer service, has evolved into a force to be reckoned with.

History of Army Birthday

The U.S. Army is 245 years old, and counting. That’s a LOT of birthday candles! The annual celebration marks the date in history in 1775 when the Continental Army was formed by the Second Continental Congress and commanded under General George Washington to fight against Britain. 

Of course, the U.S. Army wasn’t always the strongest military in the world as it is today. The original ‘army’ was formed from volunteer soldiers, amateur troops, and minutemen, who just had the passion and dedication to defend their land against the British. Actually, military forces existed in the United States before the country even formally existed. Independent colonial armies commanded inexperienced militia. 

The Revolutionary War started in America on April 19, 1775, with exchanges of musketry between Massachusetts militiamen and British regulars at Lexington and Concord. As soldiers were alerted in Connecticut, Rhode Island, and New Hampshire, they responded to the alarm, and a state of war was in the air between the British government and the four colonies. Called the Army of Observation, a force of New Englanders surrounded Boston and had the British troops who occupied it under siege, but they needed help. Delegate representatives of all 13 colonies were approached and requested to join them in the battle for American liberty. 

When the Continental Army delegates assembled on May 10 in Philadelphia, they learned that British forts at Ticonderoga and Crown Point on Lake Champlain in New York were captured by armed men led by Benedict Arnold and Ethan Allen. The situation quickly turned into a crisis, as the delegates realized that the military coup would need to be addressed if the desired reconciliation was to happen. The next step was taken by the Congress, which eventually transformed the small rebellion into a full war for independence. The establishment of the Continental Army resulted in the U.S. Army that we know today. 

There was a time when there were never more than 48,000 Continental soldiers. Today, the United States Army boasts over one million soldiers on duty, with an additional 800,000 Reserve- and National Guard members. 

The resilience of the U.S. Army and its history is a testimony to how integral the military is in peacekeeping. Gratitude is expressed tremendously on the Army’s Birthday with events and ceremonies.

Traditions of the Day

There are many annual traditions and ceremonies that honor the past and salute the efforts of the U.S. Army. The sacrifices of soldiers who put their lives on the line to protect the country are recognized and re-enacted in schools, and some local theatres. 

Cake cutting ceremonies are hosted at both Capitol Hill and the Pentagon, a tradition that has been honored over time. An Army saber is used for cutting the cake by the highest and lowest ranking officials. This is to set in stone the teamwork and brotherhood of the Army. The cake cutting tradition is a fun one, with the cake cutters getting extra enthusiastic — broken tables and flying icing are not uncommon.

It is also tradition to show the world how solid the U.S. Army is. Formation runs take place around the world, with units carrying their colors on parade fields at dawn before beginning work for the day.
