For those who like to plan their Black Friday shopping early, the first trickle of news is here: Maryland’s Arundel Mills will open for business at midnight Thanksgiving this year.

The mall opened at the same time last November, a year that many retailers started creeping into Thanksgiving dinner time by throwing their doors open as early as 8 p.m. Potomac Mills, its sister outlet, will also open at midnight.

Most retailers at Tysons Corner Center will also open at midnight Nov. 28, although some may open earlier, Bob Maurer, senior marketing manager for the mall, said in an e-mail.

Most other Washington area outlets haven’t announced their plans yet.

Retailers are making the most of a shorter holiday season, said Elizabeth Natwick, director of marketing and business development at Arundel Mills. There are four weeks between Thanksgiving and Christmas this year, compared with five weeks in 2012.

That has prompted the mall to offer extended hours during the holiday season, said Natwick. The extended hours will give retailers and customers about 40 extra hours, she said. “We’ve created our holiday schedule to open earlier and close later,” Natwick said.

Holiday sales are expected to increase nearly 4 percent to $602.1 billion, according to the National Retail Federation. Sales grew 3.5 percent last year.

The Commerce’s Department’s September retail sales report is due out Friday, but it may be canceled due to the government shutdown.
