Macy's is holding firm with its decision to open on Thanksgiving Day, and is expected to greet shoppers an hour earlier than it did in 2015.

BestBlackFriday.com, which tracks retailers' holiday deals and hours, received confirmation from five U.S. shopping centers that their Macy's locations would open at 5 p.m. Thursday. That compares with 6 p.m. in both 2014 and 2015.

A spokeswoman for Macy's did not immediately respond to CNBC's request for comment. She said last week that the company would not announce its Black Friday hours until later this month.

That includes the Mall of America, in Minnesota, and Tennessee-based CBL & Associates, which is shuttering 73of its properties until 6 a.m. Black Friday.

He added that Thanksgiving Day openings were not accretive to sales, and simply spread them out.

The following five shopping centers confirmed Macy's Thanksgiving hours to BestBlackFriday.com via phone and email. (Copies of the first two centers' emailed responses were shared with CNBC):
