Remembrance Day (also known as Poppy Day owing to the tradition of wearing a remembrance poppy) is a memorial day observed in Commonwealth member states since the end of the First World War to honour armed forces members who have died in the line of duty.[1] The day is also marked by war remembrances in several other non-Commonwealth countries. In most countries, Remembrance Day is observed on 11 November to recall the end of First World War hostilities. Hostilities ended "at the 11th hour of the 11th day of the 11th month" of 1918, in accordance with the armistice signed by representatives of Germany and the Entente between 5:12 and 5:20 that morning. ("At the 11th hour" refers to the passing of the 11th hour, or 11:00 am.) The First World War formally ended with the signing of the Treaty of Versailles on 28 June 1919.

"Abide with Me" is a Christian hymn by Scottish Anglican cleric Henry Francis Lyte. A prayer for God to stay with the speaker throughout life and in death, it was written by Lyte in 1847 as he was dying from tuberculosis. It is most often sung to the tune "Eventide" by the English organist William Henry Monk.

The "Last Post" is either an A or a B♭ bugle call, primarily within British infantry and Australian infantry regiments, or a D or an E♭ cavalry trumpet call in British cavalry and Royal Regiment of Artillery (Royal Horse Artillery and Royal Artillery), and is used at Commonwealth military funerals, and ceremonies commemorating those who have died in war.

Its duration varies typically from a little over one minute to nearly three minutes. For ceremonial use, the "Last Post" is often followed by "The Rouse", or less frequently the longer "Reveille".

The two regimental traditions have separate music for the call. While the B♭ infantry bugle version is better known, the E♭ cavalry trumpet version is used by the state trumpeters of the Household Cavalry.

The "First Post" call signals the start of the duty officer's inspection of a British Army camp's sentry posts, sounding a call at each one. First published in the 1790s, the "Last Post" call originally signalled merely that the final sentry post had been inspected, and the camp was secure for the night. In addition to its normal garrison use, the "Last Post" call had another function at the close of a day of battle. It signalled to those who were still out and wounded or separated that the fighting was done, and to follow the sound of the call to find safety and rest.

Its use in Remembrance Day ceremonies in Commonwealth nations has two generally unexpressed purposes: the first is an implied summoning of the spirits of the Fallen to the cenotaph, the second is to symbolically end the day, so that the period of silence before the "Rouse" is blown becomes in effect a ritualised night vigil. The "Last Post" as sounded at the end of inspection typically lasted for about 45 seconds; when sounded ceremonially with notes held for longer, pauses extended, and the expression mournful, typical duration could be 75 seconds or more.

This custom dates from the 17th century or earlier. It originated with British troops stationed in the Netherlands, where it drew on an older Dutch custom, called taptoe, from which comes the term tattoo as in Military tattoo. The taptoe was also used to signal the end of the day, but originated from a signal that beer taps had to be shut, hence that the day had ended. It comes from the Dutch phrase Doe den tap toe, meaning "Close the tap". The Dutch bugle call Taptoesignaal, now used for remembrance events, is not the same tune as the "Last Post".

The "Last Post" was used by British forces throughout North America in colonial times. In the United States it was replaced by the different "Taps" by the United States Army, first used in 1862 and officially recognized in 1874.

During the 19th century, the "Last Post" was also carried to the various countries of the British Empire. In all these countries, it has been incorporated into military funerals, where it is sounded as a final farewell, symbolising the fact that the duty of the dead soldier is over and that they can rest in peace.

"Last Post" is used in public ceremonials commemorating the war dead, particularly on Remembrance Day in the Commonwealth of Nations. In Australia and New Zealand it is also sounded on Anzac Day, usually before the two-minute silence, which concludes with "The Rouse".

When the post is sounded during services such as Anzac Day, it is required of all current serving military members to salute for the duration of the call. During services organised by the Royal British Legion, it is expected that no salute is given during the "Last Post" and Silence, as all personnel will have removed head dress as in church service prayer, have heads bowed, weapons inverted, and flags and standards lowered.

In the Republic of Ireland, the "Last Post" as with the Commonwealth is sounded during memorial services, funerals and commemorations. The difference where the Irish are concerned is that the accompaniment of drums is incorporated into the performance.

In India, Last Post is played at the Amar Jawan Jyoti on Republic Day and Kargil Vijay Diwas (Kargil Victory Day).
