This was the Esperanto Association of Britain's site from 2005 to 2018. You will find its current site at esperanto.org.uk.
Like the Queen, Esperanto has two birthdays each year; "Esperanto Day" on 26th July celebrates the publication of the "Unua Libro" [the "first book", in/about Esperanto], and "Zamenhof Day" [also confusingly known as "Esperanto Day"] on 15th December celebrates Zamenhof's birthday.
Esperanto Day 2010 on 26th June 2010 celebrated the birth of Esperanto 123 years ago; several radio stations responded to a press release by Brian Barker and, thanks to coordination and marshalling by the EAB Office, mentioned Esperanto on that day.
