On a Wednesday evening in late February, Meny Stambler and Rikel Deutch talked to each other on the phone for the last time before their wedding.

Both are Jewish and belong to the Hasidic community, in which tradition dictates that a bride and groom do not speak to each other for a week before they marry. On that call, the 22-year-olds, who live in Brooklyn, discussed their plans to travel to Dnipro, Ukraine, where their wedding was set to take place on March 3.

Several hours after their conversation, Mr. Stambler’s phone started ringing. Russian troops had invaded Ukraine, bombing cities and airports.

His mother and father were in Kamianske, an industrial city in the country’s center, with two of his five siblings. A third was in Dnipro, while the others were in Israel and New York. Ms. Deutch’s parents were across the border in Russia, where they live in Samara, a city in the country’s southwest. Two of her 10 siblings were also in Russia, one was in Dnipro, and the rest were in Israel and the United States.

“Slowly I started to understand that the wedding won’t happen in Ukraine,” Mr. Stambler said in a video call with Ms. Deutch from the Brooklyn apartment they now share.

The two are members of Hasidism’s Chabad movement. According to Chabad custom, changing the date of a wedding should be reserved for only the most extreme situations. Despite the invasion, the couple and their families decided to proceed as planned with their wedding date — but restage the event across the world, in New York.

“The wedding is a momentous occasion,” said Dina Deutch, Ms. Deutch’s mother, in a phone call. “Another Jewish family is being formed. No one wants to delay such a sacred event.”

Ms. Deutch and Mr. Stambler both moved to the New York City area for schooling. She relocated about eight years ago to attend middle school in Morristown, N.J., and later went to Beth Rivkah high school in Brooklyn. Afterward, Ms. Deutch moved to Israel for two years to study Judaism and graphic design, then returned to New York to work as a freelance graphic designer.

Mr. Stambler, who arrived about three years ago, is studying at Educational Institute Ohalei Torah, a yeshiva in Brooklyn.

They met for the first time last November, after an acquaintance suggested that they might make a good match. “Our first date was five hours,” Mr. Stambler said. It started in the lobby of the New York Marriott at the Brooklyn Bridge in Downtown Brooklyn, where they talked for a while. Then they “crossed the whole of Brooklyn Bridge,” to Manhattan and back, Mr. Stambler added.

Over the next five weeks, they went on hourslong dates several times a week, to restaurants, to a bowling alley, to play pool. No matter the venue or activity, conversations during their courtship always turned to the practical aspects each sought in a marriage.

“We don’t date to have fun, we date to be married,” Ms. Deutch said. “It’s very intense, talking about what we want in our lives, how we want to raise our children and all of that.”

Mr. Stambler knew early on that Ms. Deutch was the one for him. After every date, he would check in with his mother, and their conversations helped him realize how much he liked Ms. Deutch, he said.

Ms. Deutch said that although she could see herself marrying Mr. Stambler within a week and a half of meeting him, she waited a bit longer to to tell him that. While considering a life with him, she thought about the advice that her father had given her: to find someone she could talk to for hours, but with whom she could also “sit together quietly.”

After discussing a potential engagement on one of their dates, Mr. Stambler made it official in mid-December, proposing over dinner at Noi Due Cafe, a restaurant on Manhattan’s Upper West Side. But there was no ring involved.

As Mr. Stambler put it, in their culture, “If you give a girl who’s not married a ring and she puts it on, you’re now married.” Still, “he was very nervous,” Ms. Deutch said. “He couldn’t get the words out. It was very cute.”

Couples who are part of Chabad typically have short engagements; Mr. Stambler and Ms. Deutch’s engagement was about two and a half months. As Ms. Deutch’s mother explained, “The bride and groom don’t have the right to have physical contact before they’re married so they don’t wait too long.”

They initially chose a Chabad center in Dnipro, Ukraine, as the location for their wedding because of the city’s spiritual meaning to the movement. Rabbi Menachem Mendel Schneerson, the revered Chabad leader, grew up in Dnipro before eventually moving to New York, where he died in 1994. After Mr. Stambler proposed, the couple wrote a letter asking Rabbi Schneerson to bless their engagement and left it on his grave in Brooklyn.

When the decision was made to relocate their nuptials, Mr. Stambler and Ms. Deutch, who by then had begun their seven days of not speaking, relied on their families and members of their Chabad community to help them plan an entirely new celebration.

“We found a hall, a photographer, music in three days,” said Mr. Stambler. During this time, he exchanged messages with his fiancée via her sister, Mushkie Deutch, 26, who lives in New York.

They arranged for the ceremony to take place in the courtyard of the Chabad Lubavitch World Headquarters in the Crown Heights section of Brooklyn. A friend of the Stamblers who lives in New York helped them find a venue and a caterer for their reception. Ms. Deutch’s family secured the same photographer and band that they had worked with for the January wedding of her brother Yossel Deutch, 23.

On top of the logistical issues that came with replanning the event within a week, the couple also had to grapple with the emotional challenges presented by the cross-continental journeys their families had to take from warring nations to make it to their nuptials.

“One of the foundations of Judaism is that you have to trust in God, you have to trust that everything will be OK, even if you don’t see it,” Mr. Stambler said. “But I was conflicted. I’m a person, I’m suffering, I’m not an angel. I was very worried.”

In the days after Russia invaded Ukraine, Mr. Stambler’s father, Rabbi Levi Stambler of the Synagogue of Kamianske, said he was conflicted about leaving his community in the middle of a crisis. After consulting the head rabbi in the region, who told Rabbi Stambler that family has to come first, he and his wife, Dina Stambler, decided they would find a way to get to New York.

With Mr. Stambler’s sisters Rivkah Stambler, 8, and Mushi Stambler, 11, and Ms. Deutch’s brother, Shneur Deutch, 12, who was studying in Dnipro, they set out on a trip that would last more than 48 hours.

They drove toward the Ukrainian border with Moldova and were stopped at many checkpoints along the way. At one of them, Rabbi Stambler said that the military personnel told him to get out of the car and accused him of being a Russian saboteur before searching his phone and finding nothing of interest. At another, his family watched as someone was pulled out of a car and pushed to the ground to be searched.

In Moldova, they could not find any available flights. They drove on to Bucharest, Romania, where a local Jewish family took them in for the night. From Bucharest, they flew to New York.

“The whole time we were traveling, we were on the phone talking with a team at home dealing with this crisis at home,” Rabbi Stambler said. “People need insulin, blood pressure medication, and food. We need to find buses, drivers to evacuate people.”

Mr. Stambler’s brother Shmulik Stambler, 21, a counselor at a yeshiva in Dnipro, left Ukraine several days later with the rest of the school. He arrived in New York hours before the wedding.

Ms. Deutch’s father, Rabbi Shlomo Deutch of the Samara Synagogue, and mother had an equally difficult journey from Samara. It began on Feb. 27, when they, along with Ms. Deutch’s sister, Miriam Deutch, 10, took a two-hour flight to Moscow. There, the three boarded another flight, to New York.

“Halfway through, over the ocean, they announced that Canada had closed its airspace and wouldn’t allow us through,” Ms. Deutch’s mother said. The plane turned around.

“My first fear was, what if they don’t have enough fuel?” she said. “My small daughter, who’s 10, started crying. I said, ‘Everything will be OK.’ What else can I say? That I’m afraid?”

About 10 hours after it left Moscow, their flight landed back in the city, where Ms. Deutch’s brother, Asher Deutch, 15, a student in Moscow, met them at the airport. The four later boarded a flight from Moscow to Tashkent, Uzbekistan, then another to Istanbul, then another to John F. Kennedy International Airport, where they arrived on March 1 after 36 hours in transit.

With their families present, the couple wed two days later before Rabbi Chaim Shalom Deutch, the grandfather of the bride, who traveled from Jerusalem to officiate. Ahead of the ceremony, Mr. Stambler covered Ms. Deutch’s head with a veil, a tradition signifying that the groom is not just interested in the bride’s outward beauty, and that her physical appearance is to be appreciated only by him.

But first, they savored the ability to gaze at one another following their tumultuous seven days apart. “After not seeing each other for a week, after all the stress, and so many changes, this moment of seeing each other for the first time was very spiritual,” Ms. Deutch said.

It is a Chabad custom to invite strangers to a wedding, and dozens came after hearing about the long, painful journeys that both families undertook to get to New York. “It was a wedding for the whole community,” said Ms. Deutch, who has applied to legally take her husband’s surname. “Everyone was happy for us, and with us.”

After their ceremony in Brooklyn, a reception was held at Da Mikele Illagio, an event space in Queens, where more than 250 guests celebrated with the newlyweds.

All the stress in the run-up to the wedding heightened the celebratory feeling the day of, the groom said. “Even if you didn’t know the whole story, you could feel something special in the atmosphere,” he said. “We danced until the middle of the night. You could feel the joy.”

Moment of Privacy In their first truly private moment as a married couple, Mr. Stambler gave Ms. Deutch a yellow gold ring with a round diamond. After all the challenges they went through to make their wedding happen in time, he said, “it was a moment of letting go.”

Ring Around the Bride At one point during the reception, several women encircled Ms. Deutch and held a huge skirt around her as she danced in the center of it. Guests then took turns dancing with the bride as she popped balloons filled with confetti.
