NEW YORK — Tom Schrader, co-head of U.S. stock trading at Stifel Nicolaus & Co., plans to sleep in today. That’s not an option for all of his bond-market colleagues, said William Heinzerling, the firm’s head of fixed income.

The New York Stock Exchange observes the Christian holiday of Good Friday. The federal government doesn’t, sticking to its regular schedule of releasing economic reports with the potential to move markets.

This year, there’s an added wrinkle for at least the fourth time since 1996: Good Friday, whose timing depends on the cycles of the moon, coincides with the Labor Department’s employment report that’s sent out on the first Friday of every month. It’s the most influential planned event for the bond market, according to David Ader, head of government-bond strategy at CRT Capital Group in Stamford, Conn.

“I will get up and check the numbers, but I won’t worry about it for the rest of the day,” said Schrader, who works in Baltimore for St. Louis-based Stifel. “There’s nothing anybody in equities can do anyway.”

The Labor Department will publish the data at 8:30 a.m. today in Washington. Trading of futures linked to the Standard & Poor’s 500 Index and Dow Jones Industrial Average, the benchmark measures of U.S. stocks, will continue until 45 minutes later on the Chicago Mercantile Exchange.

Shares of individual companies won’t change hands on the NYSE and Nasdaq Stock Market. Exchanges from London and Sao Paulo to Paris, Frankfurt and Toronto will also be shut.

The jobs report may boost stock-trading volume on Monday, when traders and investors return to work, said David Bellantonio. He’s the head of U.S. trading in New York at Instinet, which says it handles about 4 percent of the nation’s equity transactions.

The last time monthly employment data, Good Friday and a closed stock market coincided was in 2007.

After the Labor Department said on April 6, 2007, that employers added 50,000 more jobs than economists projected, the 10-year Treasury yield jumped to an eight-week high of 4.75 percent from 4.68 percent. June futures on the S&P 500 climbed 0.4 percent. On Monday, April 9, the S&P 500 and Dow rose 0.1 percent to six-week highs.
