Towns and cities up and down the country will be celebrating the Queen's 90th birthday on June 11th-12th, while many local residents will be decking out banqueting furniture for street parties too.
Her actual birthday was in April, but each year the monarch has a second 'official' birthday in mid-June, which is another opportunity to mark the occasion, and typically delivers finer weather for outdoor parties.
At the beginning of the year, the government urged local communities to consider holding street parties for the April birthday - and this month's celebration is a good chance to do it all over again, for residents and businesses alike.
Communities secretary Greg Clark said: "There were almost 10,000 applications to councils to hold street parties for the Diamond Jubilee. I want to encourage all councils to once again get behind local people's plans to bring out the bunting."
In Leicester, for instance, the city's official 'garden party' takes place on Sunday June 12th, from 11am until 4pm in Jubilee Square.
Whether the city will set out banqueting furniture remains to be seen, but there will be food and drink available, and visitors are also invited to bring their own picnics along to enjoy as well.
"A full programme of family entertainment is on offer, as the city and county come together to mark the birthday of the year," Leicester City Council said.
"Jubilee Square will be the focus of the festivities, with a big screen in place to allow visitors to enjoy the scenes on the Mall in London. Here in Leicester, there will be live music, arts and crafts workshops and children's activities."
This is of course the latest in a sequence of major royal celebrations - with several big birthdays, anniversaries, weddings, Jubilees and births over the past few years.
Combined with the legacy of London 2012, and with another summer of sport now upon us, large-scale community festivities have found a resurgence in popularity.
For businesses and local communities alike, that makes it an even better time to invest in banqueting furniture, and make street parties, garden parties and other large celebrations a more regular occurrence in the future too.
