Tony Blair has joined licensees and the organisers of the Queen's Golden Jubilee in urging people to take part in the celebrations.
There is anxiety that the event will be a flop but pubs and pub companies are already planning entertainment which could mean critics have been premature in writing off the festivities.
Suffolk-based brewer Greene King is planning to brew a commemorative ale for the occasion which will be available from April 25 until June 8 - an idea that came from its licensees and customers.
Greene King Pub Company, the brewer's managed estate, is also planning to mark the occasion.
Spokeswoman Frances Brace said: "We want our outlets to consider mailing customers to tell them what's going on and advertising party nights and so on. There's information about health and safety and licensing issues as well."
Many licensees have already started organising celebrations for the long Bank Holiday weekend.
Extended hours have been granted until 1am on Monday June 3 and there will be an extra Bank Holiday on June 4.
