Happy St. George's Day to the English!

It's St. George's Day. I have no idea what this means, but apparently its really big in England.
I refer to Wikipedia:

St George's Day was a major feast and national holiday in England on a par with Christmas from the early 15th century.^[2] However, this tradition had waned by the end of the 18th century after the union of England and Scotland.^[3] In recent years the popularity of St George's Day appears to be increasing gradually. BBC Radio 3 had a full programme of St George's Day events in 2006, and Andrew Rosindell, Conservative MP for Romford, has been putting the argument forward in the House of Commons to make St George's Day a public holiday. Although Saint George is the Patron Saint of England, it is believed that St George was not English and it is not certain that he ever visited England, although legend has it that St George was born in Coventry at Caludon Castle in Wyken.^[4]

A traditional custom at this time was to wear a red rose in one's lapel, though with changes in fashion this is no longer common. Another custom is to fly or adorn the St George's Cross flag in some way: pubs in particular can be seen on April 23 festooned with garlands of St George's crosses. However, the modern association of the St George's Cross with sports such as football, cricket and rugby means that this tradition is rare outside this context. It is customary for the hymn "Jerusalem" to be sung in cathedrals, churches and chapels on St George's Day, or on the Sunday closest to it.

There is a growing reaction to the recent indifference to St George's Day. Organizations such as English Heritage, and the Royal Society of Saint George (a non-political English national society founded in 1894) have been joined by the more prominent St George's Day Events company (founded in 2002), with the specific aim of encouraging celebrations. They seem to be having some effect. On the other hand, there have also been calls to replace St George as patron saint of England, on the grounds that he was an obscure figure who had no direct connection with the country. However there is no obvious consensus as to whom to replace him with, though names suggested include St. Edmund, ^[5] St. Cuthbert, or St. Alban, with the latter having topped a BBC Radio 4 poll on the subject.^[6]

In early 2009 Mayor of London Boris Johnson spearheaded a campaign to encourage the celebration of St George's Day. St. George is also the patron saint of the Scouting movement. Many Scout troops in the United Kingdom take part in a St George's Day Parade on the nearest Sunday to April 23. A message from the Chief Scout is read out and the Scout Hymn is sung. A "renewal of promise" then takes place where the Scouts renew the Scout's Promise made at joining and at all Scout meetings.

St George's Day is traditionally the occasion when the Queen announces new appointments to the Order of the Garter.
