The couple, now both 27, dated until Mr. Crane had to return to school in Nashville. When he came home for Thanksgiving, she suggested that they hang out Friday evening. “I said, ‘I want a full day,’” said Mr. Crane, a managing director and the senior legal counsel at Dwight Capital, a real estate lender in New York. Both view that date as a turning point in their relationship.

After both graduated and he had returned to his parents’ house in Kings Point, N.Y., to spend the summer studying for the bar, they developed a regular date night. She’d take the train to Great Neck, and they’d go for sushi pizza, maybe a little wine, at a place his family has been patronizing for 30 years. “We always sat at the same table,” he said.

The couple had originally planned to marry on April 4 at Heritage Club at Bethpage in Farmingdale, N.Y., with 250 guests. They were reluctant to simply postpone to a later date. “The most important thing for us was getting married and we didn’t want to wait,” Mr. Crane said. “We always felt that ‘fiancé,’ ‘boyfriend-girlfriend,’ these titles weren’t strong enough to represent our commitment to each other, and how we feel about each other.”

So the couple, their parents, their siblings and the officiant, Rabbi Robert S. Widom, convened at Temple Emanuel of Great Neck on March 21, and with everyone maintaining suggested distances they were married. They streamed the ceremony live to about 100 friends and family. The bride wore a white dress, though not her wedding dress, and the groom wore a suit, not his wedding tuxedo. Afterward, the wedding party shared a glass of champagne in the synagogue’s parking lot. Again, at a careful distance.

And then the newlyweds headed to East Quogue, N.Y., not far from the place where they had met, to a house they had rented the day before their marriage. They plan an entire month of honeymooning in place.

They haven’t yet been able to reschedule the ceremony before friends and family, with so many other couples also working to do the same thing. “It’s really all up in the air,” Ms. Weiner said.
