Here's why May the 4th is celebrated as Star Wars Day across the galaxy

It didn't begin a long time ago or in a galaxy far far away, but every May 4 it feels like images, memes and promotional deals involving “Star Wars” have an inescapable gravity.

May 4 — or May the 4th, as fans say — has evolved over the years into Star Wars Day, an informal holiday celebrating the space epic and its surrounding franchise.

Star Wars Day was created by fans as a sly nod to one of the films' most popular catchphrases, “May the force be with you.” Get it? Good, now May the 4th be with you too.

It's not an official holiday but has become so well-known that even former President Joe Biden marked it last year when “Star Wars” actor Mark Hamill dropped by the White House a day beforehand. This year, the Trump administration marked the occasion with a Star Wars-themed meme.

“I think it's a very clever way for fans to celebrate their passion and love for ‘Star Wars’ once a year,” said Steve Sansweet, founder and executive chairman of Rancho Obi-Wan, a nonprofit museum in California that has the world's largest collection of “Star Wars” memorabilia.

The phrase “May the 4th be with you” was used by fans in the years after the first film was released in 1977, and even appeared in a British political ad in 1979 celebrating Margaret Thatcher's victory as prime minister on May 4 that year.

For some fans, the official Star Wars Day comes on May 25, the date of the first film's release. The Los Angeles City Council even declared the date to be Star Wars Day in 2007, although the California Legislature voted in 2019 to designate May 4 as Star Wars Day.

May the 4th caught on informally among fans through inside jokes shared on social media and viewings of the films to mark the occasion. Businesses eventually joined in on the fun, with brands ranging from Nissan to Jameson Whiskey running ads or posting on social media about it.

Disney, which acquired Lucasfilm in 2012, embraced the day as a way to further promote the franchise with merchandise, special screenings and other events surrounding the brand.

Not all “Star Wars” fans are enthused about how ubiquitous the once-underground joke has become. Chris Taylor, a senior editor at Mashable and author of “How Star Wars Conquered the Universe,” labels himself a “May the 4th grinch" in part because of its commercialization.

“I love a good dad joke as much as anyone, but my God you can take it too far,” Taylor said.

In western Germany, a Protestant congregation held a Star Wars-themed service Sunday, German news agency dpa reported. Pastor Samuel Dörr and some of his congregants wore costumes and decorated their church in Bensberg.

The day is being celebrated on a large and small scale this year. Disney+ is launching the new series “Star Wars: Tales of the Underworld” on the date, and it comes as the second season gets underway for another franchise series, “Andor.”

It also follows the announcement that a new stand-alone “Star Wars” film installment starring Ryan Gosling will be released in 2027.

Disney marks the day with the launch of new “Star Wars” merchandise, ranging from lightsaber sets to jewelry.

Most Major League Baseball teams have marked the day in recent years with special events incorporating “Star Wars” characters. For example, the San Francisco Giants sold special tickets for Saturday's game that included a bobblehead portraying pitcher Logan Webb as “Obi-Webb Kenobi.”

It's hard to find a place where May the 4th celebrations aren't occurring, from bakeries serving cookies with a “Star Wars” theme to concerts featuring the memorable scores of the films.

It's a town-wide celebration in New Hope, Pennsylvania, which shares its name with the subtitle of the first “Star Wars” film. The town of about 2,600 people, located 30 miles (50 kilometers) northeast of Philadelphia, plans to have costumed characters throughout town with restaurants serving themed items like a “YodaRita.”

“I would always joke around and wish people ‘May the 4th’ — but taking it to this level, I've definitely upped my ‘Star Wars’ nerdiness,” said Michael Sklar, president of the Greater New Hope Chamber of Commerce.

The White House posted an AI-generated image of a muscular Donald Trump in a jedi robe and wielding a red lightsaber. The image on X was accompanied by a Star Wars-themed broadside.

“Happy May the 4th to all, including the Radical Left Lunatics who are fighting so hard to to bring Sith Lords, Murderers, Drug Lords, Dangerous Prisoners, & well known MS-13 Gang Members, back into our Galaxy. You’re not the Rebellion—you’re the Empire,” the White House posting said.

KYOTO, Japan--(BUSINESS WIRE)--Jun 15, 2026--

Murata Manufacturing Co., Ltd. (TOKYO: 6981) (ISIN: JP3914400001) announces a new collaboration with Synopsys, Inc., enabling users of Synopsys' simulation tools to navigate directly to Murata's website to access and download the latest high-performance simulation models from Murata. The collaboration covers Synopsys' 3D electromagnetic field analysis tool Ansys HFSS™ and thermal analysis tool Ansys Icepak®, and marks a significant step toward streamlining the simulation workflow for electronic circuit designers. Murata is also the first company to offer passive component simulation models via Ansys Icepak*.

This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20260615241645/en/

As demand for high-speed, high-capacity communications continues to grow, electronic circuit design has become increasingly complex. Engineers must now account for a range of physical phenomena, from electromagnetic interference (EMI) to component heat generation, within a single design. Addressing these challenges early in the design process is critical; overlooking them can trigger costly redesigns, extend development timelines, and drive up prototyping expenses. This has placed greater pressure on electronic component suppliers to provide ready-to-use, high-quality simulation models that are compatible with the tools engineers already rely on.

Developing accurate models for electromagnetic and thermal analysis is inherently challenging, as both electromagnetic behavior and temperature distribution shift considerably depending on design conditions. Murata's vertically integrated approach, spanning raw material development and manufacturing through to final product processing, enables the company to draw on an extensive proprietary dataset, resulting in simulation models that closely reflect real-world component performance.

The models are compatible with Ansys 2026 R1. Ansys HFSS supports electromagnetic field analysis and covers Murata's RF inductors and multilayer ceramic capacitors (MLCCs), while Ansys Icepak supports thermal analysis and covers Murata's power inductors.

Looking ahead, Murata will continue to deepen its collaboration with Synopsys, expanding its model lineup to support more advanced and efficient electronic design.

The following data is available for download from Murata's website:
Electromagnetic field analysis data for Ansys HFSS — RF inductors
Electromagnetic field analysis data for Ansys HFSS — MLCCs
Thermal analysis data for Ansys Icepak — Power inductors
