NEW YORK » From fireworks soaring above the Washington Monument to hot dogs being downed in New York City’s famed frank-eating contest, Americans aren’t shy about celebrating their nation’s birthday. Many places are rolling out long-established Independence Day traditions today (even if some of those traditions aren’t as long-established as they sound). Some communities are trying new things to mark the holiday, even as others are paring back. Some Fourth of July highlights from around the country:

IN THE NATION’S BIRTHPLACE, A PARADE AND A PARKWAY PARTY

In Philadelphia — where the founding fathers approved the Declaration of Independence on July 4, 1776 — the national birthday party runs all day.

It kicks off at 10 a.m. with a reading of the document and an event honoring everyday heroes, with celebrity guest Leslie Odom Jr., a Philadelphia native who plays Aaron Burr in the Broadway musical “Hamilton.” Then comes the holiday parade, which includes Miss America 2016 Betty Cantrell.

Next up is a five-hour party with free entertainment on the Benjamin Franklin Parkway. The celebration continues with a five-hour concert with performers including Odom and singer-songwriter Leon Bridges. Fireworks close out the day.

A FINAL WHITE HOUSE FOURTH FOR THE PRESIDENT

It’s the last Fourth of July at the White House for President Barack Obama and his family, and they’re having some people over: military families and two of the president’s favorite performers, singer-songwriter Janelle Monae and rapper Kendrick Lamar.

The Democratic president and his wife, Michelle, invite military families each year for a barbecue, concert and view of the fireworks on the National Mall.

This year, they’ll also hear Lamar — Obama said his favorite song of 2015 was the rapper’s “How Much a Dollar Cost” — and Monae, who was a guest at a White House state dinner in May.

NEW YORK: FRANKS AND FIREWORKS

American as apple pie? Fuhgeddaboudit. The frankfurter rules the Fourth in New York City, where the annual Nathan’s Famous hot dog eating contest marks its centennial this year — well, not really. Nathan’s itself dates to 1916, but showmen behind the hot dog competition have acknowledged they made up a long-told story about the contest beginning that year, too. It actually started in the 1970s.

Joey “Jaws” Chestnut set the world record in 2013 when he polished off 69 dogs in 10 minutes. His run of eight straight victories ended last year when he lost the Mustard Yellow International Belt to Matt “The Megatoad” Stonie. They and others will face off on the Coney Island boardwalk, with the chowdown showdown televised on ESPN3.

Later today, Macy’s is promising its biggest Fourth of July fireworks display since the millennium show of 2000. The show over the East River features more than 56,000 pyrotechnic shells, 22 different hues and the New York debut of “pyro-writing” in the sky, all synchronized to patriotic tunes performed by the United States Air Force Band. The fireworks are televised on NBC, along with performances by country singer Kenny Chesney, pop band 5 Seconds of Summer, pop singer Meghan Trainor and others.

BOSTON’S BLOWOUT

Hundreds of thousands of people are expected to line the banks of Boston’s Charles River to watch the fireworks there, with millions more across the country watching live on CBS.

The celebration features pop stars Nick Jonas and Demi Lovato, country group Little Big Town and, as always, the Boston Pops Orchestra, which drives home the climactic fireworks finale to Tchaikovsky’s “1812 Overture.”

ONE CONNECTICUT CITY’S NEW CELEBRATION; ANOTHER CANCELS ITS OWN

New Haven’s newly renovated Q Bridge will be illuminated in red, white and blue at night, becoming Connecticut’s first bridge to feature commemorative lighting.

The lights are capable of projecting six miles in a clear night sky over what’s formally called the Pearl Harbor Memorial Bridge. It’s among the most heavily traveled segments of the northeast corridor between New York and Boston.

Meanwhile, the state capital of Hartford canceled its July Fourth festival and fireworks show, which is billed as Connecticut’s largest Independence Day celebration, though usually held a week after the holiday. The mayors of Hartford and neighboring East Hartford said they couldn’t justify the roughly $100,000 expense while facing painful spending cuts.

JULY FOURTH, CALIFORNIA-STYLE

There’s a something-for-everyone approach to fireworks in Los Angeles, where displays are planned at the Los Angeles Memorial Coliseum, the Hollywood Bowl, Grand Park near City Hall and the Rose Bowl in Pasadena, among other places around the massive metro area. San Francisco holds a large fireworks display over the San Francisco Bay.
